Capacitor issue

Hi everyone,
first af all let me apologize for my lack of technical skill, I'll hope to explain clearly my present problem.
I recently opened the case of my pc in order to install a new fan and remove a crap dvd writer. After that I noticed a weird flickering in my monitor.
Once I were sure it didn't depend on some driver or configuration issue, I re-opened the case and found ( ) a broken capacitator (or at least i suppose it's a capacitator: a very small and thin black and white ceramic cylinder with two metal leads at his black plastic base). Lookind deeper at the mobo I found that the original emplacement of the item was just close to the AGP slot, right beneath the graphic card. Moreover, the capacitator isn't really broken, but it just detached form the Mobo (or better, clumsy me detached it ).
So my questions are:
-is it possible that the flickering depends on the detsched capacitator (given its position it's the first thing I thought)?
-what the heck is the purpose of a capacitator (and you're allowed to laugh at me for this question)?
-how can i fix it?
Concerning the latter point: which is the right position (white means negative?)? And am i supposed to solder it or may an epoxy glue make the job as well?
Thanks for your patience!

thanks again for the moral support, raven.
and hail to thee, glenn, for thy english class.
concernimg this latter point:
1) it's pretty obviouv that english is not my mother tongue
2) as a matter of fact i'm italian
3) i performed a long web research before posting my issue, for the simple reason that i didn't have any clue idea about the nature of that little piece of my mobo i unfortunately set free
4) i found both capacitor and capacitator, but i didn't realize that the second was wrong
5) i don't even know how to call it in italian. mabbe (thanks once more raven) "condensatore elettrolitico" or perhaps "piccolo cilindro di ceramica mezzo nero e mezzo bianco, con alla base due linguette metalliche che ne permettono l'installazione su apposito supporto".
ciao guys

MSI R4830 OC : The exploding capacitor issue still continuing?

For reference, my system spec:
MSI 790FX-GD70 mainboard
AMD Phenom II X4 955 BE
4GB OCZ Platinum 1600MHz memory
MSI R4830 OC graphics
1TB WD & 500GB Seagate harddrives
OS: Windows 7 Ultimate
System isn't overclocked and has never been.
The story...
Today after doing a bit of gaming (WoW) all of a sudden my computer BSOD'ed and after the auto-reboot of W7, the bios gave me an error notification saying: "a hyper transport sync flood error occurred on last boot. Press F1 to continue". After just continuing Windows booted fine and I was able to run the regular programs without any issues. Wanting to continue gaming, I again started WoW, and even before I got into the login screen, windows BSOD'ed again, after which the bios again came back with the hyper transport sync error.
Doing some research on the error, I came to a conclusion, that there apperently are many reasons why it occurs, but no single sollution to solve it. So I just continued, let my computer be for a moment, and idle'ing it for a couple of hours. During that time no issues at all.
Until about an hour ago... I wanted to try to get WoW started again and amazingly it did, without crashing. Until I was in the game for about 5 minutes and then the computer did NOT BSOD this time, but immediately did a full powerdown. Trying to power it up again after that failed, after taking the PSU of the mains and plugging it in again, the system would "turn on" for less then a second and immediately powered down again.
Time for some hardware inspection then. Took of the harddrives & dvd (power & sata) to no avail. The system would still only "turn on" for less then a second. Next to be taken out was the graphics card (MSI R4830 OC), after removing it the system would turn on again and stay on this time. So there it was... some sort of failure in the graphics card. After powering down again and inserting the graphics card again and then again trying to turn on the system, back to the previous situation where it would only "turn on" for less then a second.
This made it obvious that there was only a single cause to the entire situation and that's the graphics card.
After inspecting the graphics card I noticed the following:
(Click to see a larger version of the photo)
Note the upper most capacitor, it was bloated and had been leaking. Off all the capacitors on the board (most of them are solid-state caps, only 5 classic caps) this the only one that burst.
Seeing this immediately makes me remember the situation we had about 8 years ago, with exploding capacitors all over the place (I have seen much of my hardware in those year fail due to exploding caps): http://en.wikipedia.org/wiki/Capacitor_plague
Considering the location of the capacitor near the power connector of the board, I suspect the capacitor to be related to handling the power supply from that connector. If that is the case, most likely the board might not receive (enough) power from the PSU to power the board, causing the PCI-E power usage to run to high, in turn causing the mainboard to turn of for safety.
How long this capacitor has been blown I don't know, but I wished I would have noted earlier. Until today everything worked fine, but it could very well be this cap was already blown for months.
As a final question, has anyone else recently had any exploding capacitors on MSI products (and I'm not talking about hardware from the problem era, but rather the more recent hardware, in which the capacitor issue should have been solved long time ago)?

The card is produced early 2009, so technically from the period after the issues there were with the bad Taiwanese caps. Out of the 15 caps on the board in total, 10 are solid-states and only 5 are still the old electrolyte ones, of which one obviously blew.
And indeed I am aware of what they are used for and what issues they cause if they go bad. Have seen approx. 20-30 motherboards & another 10 graphics cards fail due to exploding caps during the time where the issue arose with the stolen electrolyte. (Luckily only a few mainboards were actually mine, but had many friends and family members with the issue).
This is the first time I've seen the issue come up since around 2008 when an old socket 7 board blew which was owned by a family member.
I do wonder though how the unstable graphics card is related to the "hyper transport sync flood error", if at least this blown cap is the one and only reason my system BSOD'ed.

EMac sharing iMac capacitor issue

Hi iMac G5 owners,
I just thought it may be of some interest that the bad capacitor problem that resulted in Apple starting a Repair Program for the iMac G5 is now also affecting the eMac G4 1.25Ghz machine, which ceased production on the same month as the iMac G5.
Is there anyone here who was affected by this problem? How did you find out about the problem (ie that it wasn't just you)? Had Apple already instigated the repair program by the time your machine was affected?
cheers
Travis

No offense taken, Eric, honest.
The reason I single out Mac first timers is because we are the underdog, and it would be fair to say they are taking a big leap from PC to Mac. The eMac was an ideal "first timers" computer - cheap, but still powerful, and pretty. There are a lot of people still looking for eMacs today, though from what I can gather they are education only, if available at all.
I don't know about US Consumer Law, but I am fairly sure that Australian Consumer Law states that a product should live through a reasonable life span. For example I had a car battery that died after 13 months. The companies warranty was 12 months. They were however obligated to replace it, as a car battery should last longer than 13 months. A computer I would think should last longer than 20 months.
I agree that time is needed for Apple to determine how many eMacs are affected, and if so, to ensure there are enough new logic boards available before going public with a repair program. It is just very disheartening reading the posts that just keep on coming in every day, and the only reply Apple has made to date was not words but actions - they deleted "our" attempt to make an official list of eMac serial numbers suffering this problem (the list simply was re-established on MacFixIt.com).

EMac capacitor issue with pics

G'day,
Sorry to be starting a new thread on this, but with over 130 posts on the other thread, it's a bit hard to follow.
I just opened up my eMac's RAM/Battery portal (underneath the eMac, need a normal screwdriver to access, doesn't void warranties etc, not that it matters for most of us as we don't have applecare anyway). This is what I found:

http://members.optusnet.com.au/thecosmichobo/caps.jpg
My fiance could even tell what was wrong without having any idea what she was looking at.
I suggest those experiencing these freezing problems have a look under that cover to see if those 2 capacitors are doing the same thing. From other pictures online, there are a fair few more capacitors in other places not so easily visible, but it's a starting point. If 1 is doing it, and they're all from the same batch, then it will only be a matter of time...
APPLE - Please listen!
Cheers

A few people at appletalk.com.au are suggesting to
try replace the capacitors... but I'm not going to
attempt it... too many variables... and still hoping
Apple will start a repair program.
That's my Plan B: if Apple doesn't repair my unit under a program I'm simply going to take my logic board to a PC electronics shop and have them cut off the bad caps and solder on new ones, or give these guys a call:
http://www.badcaps.net.
It could probably be done for less than $100-US—far cheaper than an Apple replacement logic board that's likely to still have bad caps on it!

Dying to understand what my issue is here!

I was given an iMac, and was told if I could fix it, I could have it. iMac/iSight G5 17" w/ 10.4.11. I was told the machine had a few bad capacitors. He said he was using the machine and it restarted, and never would load again.
When I got the machine, it would come up to the spinning gear, with an apple in background, but wouldn't load. After hundreds of tries, I tried to boot into safe mode. I found out there was a password on the account, so I gave up. When I turned the machine on the next day, it booted up to the Mac OS X login screen like nothing had ever happened. I'm able to use the Mac, however, Safari quits unexpectedly, loses bookmarks and history.
Permissions have slowly somehow been changed to where I can nearly do nothing. Any attempt to correct permissions freezes the computer.
The last time it froze, it started me up at the "Welcome to your new iMac" screen, and made me enter my information. All previous user information was deleted inadvertently.
In my training, which never covered Mac, this kind of problem was nearly always software. Does this sound like a capacitor issue? Any light that could be shone on this issue would be greatly appreciated.
I do not have the install disc that came with this computer, I was also wondering what the best solution is for that? Thanks in advance!

I'm afraid that Apple are totally justified in charging what is a nominal sum for discs that you should already possess. Blame the person who gave you the computer without the discs, which should always accompany any computer that is passed on to someone else. The fact that you were given the computer makes your complaint even less understandable.
I won't be blaming anyone due to the circumstances. The person who "gave" me the computer owes me alot of money. So I've paid for this computer, "gave" is not the right word. And I absolutely agree, keep and take care of your discs.
I just think it should be available online, even if it is at the same price. Persons with disabilities can truly struggle to take care of discs. I'm sure somewhere somebody shares this frustration. I was not trying to make a complaint. I was suggesting a second option that I figured might be available.
I bought the disc without saying a word, and treated the person on the phone with respect.
Is popping open the computer and examining the caps the only good way to tell if my issues are cap related?
Thnx MGW

What kind of problems can leaking capacitors cause?

I inherited a faulty iMac G5 from a family member. It would not boot up and the service center that dealt with it said the hard drive was bad. It was still functional enough to extract valuable data from it, though. I surmised that it wasn't really "bad"... just suffering from some damaged system files or directory structure.
With all valuable data copied off of the drive, I figured it would be best to completely wipe it and install fresh. However, during the process the system would crash before installation completed. In a few cases that I tried this, I could boot off of the 2nd DVD and actually interface with the system. But, any running of the Disk Utility on the internal HDD volume would trigger a crash. Running "fsck -fy" in single user mode would reveal errors, but the system couldn't fix them all. And then at some points, I couldn't even get single user mode to work without crashing.
Long story short, I tested out the install with just one memory DIMM installed in slot 0, and found that it worked a little better with one of the DIMMs. I was able to run another erase/install again. FINALLY, the computer is working OK without crashes.
However, in doing this whole troubleshooting adventure, I noticed that a number of capacitors (maybe 5 or 6) are leaking slightly from the top. You can see a tiny dollup of beige powder in the middle of the vent lines on top . I read up on faulty capacitors and they can cause voltage fluctuations seemingly at random. And this can wreak havoc on hardware.
So... I need to isolate this down a bit. I ran the disk utility and the HDD checks out fine now. If it was wearing out, wouldn't it continue to show up as faulty? I'm starting to wonder if a coincidence of capacitor issues caused bad data to get written to the hard drive and screw it up. Also, I'm wondering if any of the faulty capacitors could be in the circuitry path of the memory, that might cause it to experience subtle flaws and introduce errors... or even become damaged.
Lastly, any leaking capacitors means that they should be replaced and that it may be a gamble as to how long they'll continue to work before more serious problems arise. Is there any rule of thumb about this where the G5 is concerned? If the leaking is minor and no bulging of the capacitors is evident, might the computer work fine for a while, at least a few months until I'm able to embark on a capacitor refresh project?
Thanks for any relevant advice.

It's not worthwhile investing too much time or money in one of these. I had 3 logic boards replaced by Apple, all of which failed because they used refurbished boards, either with the same bad caps or boards that had been lying around for ages where the replaced caps slowly went bad over time from not having been formed. In fact, replacing the caps with known good ones would have been preferable to getting a replacement board from Apple.
The last board was the coup de grace, with the video chip failing -- another common issue with these turkeys.
My guess is the memory slot might be bad or that module. I've never heard of the caps fouling that part of the computer. But that's just my guess. I'd just keep using it until it dies, but I would be sure to have a backup (a bootable clone would be my preference) on an external drive so you don't lose all your data if and when it suddenly goes out.
But caps are relatively cheap and if you have the time, the expertise and the confidence....
See Spudnuty's posts on caps. He hasn't been around in a while, but he was the resident guru on fixing these things with bad caps. He did that all the time, but the video chip failure is probably insurmountable.

FYI Bulging cap issue surfaces again

My iMac G5 (20" Rev B 2.0 Ghz) bit the dust. The machine boots but there is no display. I thought perhaps the video card had died, as it has been acting a bit weird (black backgrounds where there should be white, some weird artifacting in Photoshop). So I open the back and guess what--one of the capacitors is blown. My iMac was NOT in the group of serial numbers, as this was only to have affected Rev A iMacs. Guess not!
I sold it for parts. But I feel disgusted because I upgraded the machine quite a bit last year, hoping to get another year out of it. This iMac has been the most troublesome Mac I've ever owned--it was a lemon from the start. The power supply died suddenly (common issue with these). The extreme heat of the G5 processor killed the hard drive (it used to reach temperatures of 190 degrees!). And now this.
So I just wanted to pass on that the bad capacitor issue is also on the Rev B iMacs. They also should have been given a recall, but were not (mine was one of the earliest of those models and I am sure there will still some of those crappy capacitors around.)
Here is hoping my new 24" iMac will be better!

I am curious-are you sure that they were the same capacitors? The only reason I am asking is that even good capacitors will go bad from time to time. Unless you had this thing on a quality UPS (and even then for that matter) you don't know that a power surge didn't wipe them out.

EMac issue Big One!!

Hello,
I am an A+ certified PC Repair Tech. I run an eMac at home for graphic design and games. I was raised on mac but around here everyone is PC driven. My emac recently started locking up and then soon after started locking up with jitters on the screen. First thing I did was reseat my ram, then replaced the ram.. I opened the case and looked at the bottom of the "logic board" it has two capacitors that are kinda raised up. I am also in college for my second degree in graphic design and this computer is a major key in my education. My old iMac flower power cannot run Macromedia Suite 8 at all. MY S/N is not on the list, but it seems to be affected by the capacitor issue. Is apple accepting other machines other than the ones on the list? Also is there anything I can do to get the computer to function correctly. I tried the shift thing but then I cannot connect to the internet as I am one of the few dinosaurs out there on 56K.
Thanks
Robby

I have an iMac flower power, and the main reason for getting the emac was the iMac was becomming too slow to function on anything new. I run Macromedia Suite 8. I might borrow a old G4 tower from college and use that. Until I can get my eMac fixed. Does anyone know if Suite 8 will function on a 500Mhz G3 with 768MB ram? I am glad that my machine does fit in the repair options. Since I know I might call up the Apple Store and get my father to help me get it down there. I am pretty swift with Apple software I would not delete any extensions. I have used Mac since I was 4 y/o. and I deleted some extensions on OS 9 once and it was not pretty.. I've never had an OS X reason to before.. Thanks for your help..

MSI won't warranty MB with faulty capacitors

Has anyone else experienced this dealing with MSI ?
We sent back 3 P4 socket 478 MBs (well under 2 years old) to MSI as all 3 had bulging / leaking capacitors and the systems were rebooting by themselves or locking up all the time doing a simple thing like opening up Notepad. All 3 boards were in systems in different places, healthcare facility, nursing home and call center and all in good, clean environments.
The problem of bad capacitors on MBs is well documented and very well known now.
However, we got all 3 MBs returned to us without repair. When queried about this, MSI's responses were (summarised) :-
a) "The faulty is considered to be CID (customer induced deficit)." (word for word, grammar mistakes included)
and
b) "Warranty is only limited to those capacities without physical/appearance damage. "
MSI will not warranty those MBs.
Now, how is this (a very well known issue with these capacitors) :-
a) the fault of the customer
and
b) how can you limit the warranty to capacitors that don't show signs of physical damage ?????
We have dealt with Intel, Gigabyte and Asus and all have replaced MBs still within warranty periods that have the same blown capacitor issue. This is the first time we have come across a manufacturer that refuses to warranty their boards on this very well known and common problem. On top of that, to give us the responses above !!!

Hi NovJoe,
Up until a month ago, I could still purchase MSI socket 478 boards from Ingram.
The way I look at it, EOL or not, the boards are still under warranty and I would have thought that Ingram or MSI would be obligated under the law to honour that warranty. They cannot hide behind excuses like :-
a) "The faulty is considered to be CID (customer induced deficit)."
and
b) "Warranty is only limited to those capacities without physical/appearance damage. "

IMac G5 20" power supply problem

The power supply on my 20" G5 recently fried. Somehow I had the activity monitor showing that the "FaxJobMgr" was using about 70% of my cpu. I had had that problem before and the computer was very warm. I quit that process but shortly after that there was an acrid smell that I ultimately found was coming from the power supply. When I re-started everything came up to the desktop but then it shut down just as if the plug were pulled. I see that there were many issues with the power supply on this first generation G5. I took it to the Apple Store and they say it is the power supply AND there appears to also be damage to the logic board. $734. I'm wondering if maybe its only the power supply and they are just being cautious that there might be damage to the logic board so just replace it or buy a new computer. I thought I might try to replace the power supply only, but then that seems to be about a $120 that might be gone. Any thoughts would be greatly appreciated. Thanks

Generally speaking, the defects which affect a logic board and power supply in that family of products are similar, but there typically exists no causal link between them. It is possible to have a logic board affected by the defective electrolytic capacitor issue, a defective power supply, or both.
You can readily determine if the logic board is defective by examining the clusters of capacitors on the logic board for bloating, distended tops or leakage. If they exhibit such symptoms, your logic board can be repaired for $ 189.00 by contacting this company.
You may also need to replace the power supply, thought that determination is best made once the logic board as been verified as good or bad, and replaced, if you elect to do so. Power supplies for this product family generally cost roughly $ 139.00, and are user replaceable. Replacing the supply in a unit which exhibits the defective capacitor issue will not correct the logic board related problem, and may—under relatively rare circumstances—cause the eventual failure of the replacement supply.

Freezing iMac G5 with random red and black pixels, HELP!

Hello all, and thanks in advance for helping. Here's my dilemma: I have a 20" iMac G5 that I have been using for 2-3 years or so. I recently started doing less work on it, as I replaced it with a new 24" iMac, so now it is used for one or two programs as well as occasional internet use. The system began to become slower, then finally started freezing between minimal tasks, even something as simple as pressing TAB in Safari, to trying to make a new folder in iPhoto. We restarted a bunch of times, and even tried clearing the PRAM. Now, it freezes during the start-up and there's little red and black boxes (small, maybe 4x4 or 6x6 worth of pixels) appearing randomly on the screen. When we are able to get the system to start, after one or two small tasks (opening the Address Book, or starting Safari) the program freezes, the pinwheel starts spinning, and I lose any chance to do anything more on the computer without powering down. Any advice or suggestions is appreciated! Thanks and I look forward to hearing from you.

Hi PPRI and Miriam,
Same deal going on here. It's been a while since I last posted - meaning no problems (which is goooood). So here is the issue:
Would stop at blue screen before loading to main screen. Minor repair on HD volume, and now freezes on main screen very quickly, after booting past blue screen. A few wierd pixels are seen, which lets me know that it has frozen.
Here's what I did:
Hardware check with utility - no problems found, including logic board. From the manual, it seems like it is a software issue.
As before, I repaired a few permissions and minor repair on HD volume. Still not working.
Also opened up my vents and carefully vacuumed the dust - fans were spinning hard. Still, not working.
My next step is to do an archive & install. I'm not sure how to backup my files, so this will have to suffice. This leads me to my questions:
Q1 - How do you burn a backup, without an external HD and without being able to get past my main screen?
Q2 - I noticed a post before this one, concerning the same issue, with Miriam posting on it. Is it overkill to post the same problem/question in another thread in order to maximize the chances for a good response? Any suggestions Miriam?
Thank you for being so helpful. Apple community rocks!
(PS - will let you know how the archive/install goes. If it doesn't work, I may pay to back my files on disc, and then I'll try reformatting HD altogether. Again, will let you know how it goes).
(PS2 - Not sure if this matters, but my imac was one the ones that needed the free extended warranty for the capacitor issues - identified by the serial numbers. Doubt that's the problem since it was working fine after repairs).

Imac G5 needs new logic board

Hi,
My imac G5 was revving up quite a bit and acted like I was downloading something all the time. I thought it might just need the fans to be cleaned but I took it into the genius bar and was told that they guy "thinks" that I need a new logic board but isn't positive and would I like to look at the new imacs. ( I love looking at the new imacs but it's not in my budget). He said it would cost close to $800.00 to repair my imac. I edit video on it and it's also become the family computer. Any suggestions? Do I put the money into replacing the logic board? Do I put money into expanding the memory on my macbook pro that only has 2 gb of memory?

Has it been shutting down unexpectedly?
There was a repair extension program for some of these iMacs which suffered from defective capacitors on the Logic Board and the Power Supply. It's been closed since Dec. 08, but I've heard of people appealing to Apple Customer Service anyway and getting the repairs covered. First you should open the computer and determine if the capacitors on the Logic Board are swelling or leaking at all. If so, you might be able to convince Apple to do the repairs. 1-800-275-2273. If at first you get turned down, ask to speak to a higher level rep.
Tell them how unfair you think it is that those who had the problem before the program closed were covered, and it was just your bad luck that your computer lasted a bit longer. You can also say that had you opened it up earlier, you probably would have seen the bad capacitor issue developing before the program closed. They are numerous little cylinders about 3/4 inch tall. The tops should be perfectly flat. No brownish gunk. Inspect it very carefully.You won't be able to look inside the Power Supply easily, though. If your iMac is not an iSight, it's very easy to open up. Just three screws at the bottom. Have a look here for illustrated instructions for your model. If it is an iSight, probably best not to try; a bit too complicated. Or you might just call the repair service and ask exactly why they thought it needed a new Logic Board. Did they see bad capacitors?

[info only] 2.6.33.3-2 nvidia-96xx freezes - errors

I started noticing some strange freezes in Stumpwm today. At first I suspected stump since I just started using it recently but then kde did the same thing upon reboot. The system would start freezing for a while, lockup (no keyboard input), graphics display would appear corrupted, etc. Investigating the logs I found:

After considering things I decided to simply switch back to Nouveau from nvidia-96xx. I've yet to see the problem reoccur yet since doing so. I will update if it does. I only started getting these errors in the logs after having these problems. Investigating past logs show that they have never appeared before as far as I can see.
Some hardware and config info:
01:00.0 VGA compatible controller: nVidia Corporation NV18 [GeForce4 MX 4000] (rev c1)
Linux arch-desktop 2.6.33-ARCH #1 SMP PREEMPT Sun May 2 08:21:02 UTC 2010 i686 Intel(R) Pentium(R) 4 CPU 3.00GHz GenuineIntel GNU/Linux
Recently upgraded the kernel but I rebooted a few days ago and did not notice this before:
[2010-05-09 20:25] upgraded kernel26-firmware (2.6.33.3-1 -> 2.6.33.3-2)
This isn't a big deal to me as I prefer using nouveau anyway but I wanted to share this because I would not be surprised if others see it. Just a little info for anyone who runs into this and does a search on these errors....

Thought I had better follow up on this in case someone relied on this information. The problem reoccurred this morning with the Nouveau driver. Upon investigating I found two blown (gapping holes, leaking) capacitors on the Nvidia card. This might also be related to previous system instability which I have been experiencing the last few months (I was unable to find evidence of capacitor issues on the motherboard itself). I'm using a backup video card at this time.

Strange lines and parts of characters missing in the text and freezing iss

Recently our emac has been displaying squiggles or dashes randomly on the pages and sometimes parts of the letters are missing. We have also been recently having issues with the emac freezing while using Safari and itunes. I have checked on the Repair List and our mac has a serial # that falls into the effected models. Could these problems be related to that? I have been having a hard time finding my receipt and warranty info. I know we bought the extended warranty but I can't remember for how long. We purchased it in late 2005, early 2006. I don't really want to haul it into the retailer if these problems are related. Any help would be appreciated....Thanks

Yes, it does sound as though your eMac has been affected by the infamous "bad capacitor" issues. A way to check if it is without going to the Apple Store is to power the eMac off, and open up the RAM access slot. If you see the capacitors bulging, then you can go get your logic board replaced for free, and that will fix the issues.

And here's what that did:

There have been some reports of people putting in new capacitors by themselves, but taking it to the Apple Store is probably a better idea. First of all, it doesn't void the warranty. Second of all, it's free. And a lot easier.

Suddenly, TC won't unmount

Time Machine has been working flawlessly since I got my TC, but now all of a sudden, the drive will not unmount after finishing a backup like it always has. Any reason why?

As they age they become less reliable..
What kind of modem and broadband are you using??
If it is gen 3 I suspect your TC is suffering from onset of board capacitor issues..
Please give me the A1xxx model number from the rubber mat on the bottom.
Do the setup that you know is correct.
Leave the TC off overnight to completely cool down.. start it up again the next day.. see if it will work.
If you get it working but it fails after a few minutes.. you are suffering A1355 early board failure.
If it doesnt work at all, try to use just wireless.
Set the wan ethernet speed down to 10mbit.
You will not be able to do that using the v6 airport toyland utility.. you need to use 5.6 which can be tricked into working on Mountain Lion.
Simply download the utility.. and unpkg..

Run unpkg.. click the dmg airport utility and drag the pkg file over unpkg.. it will load it to a new directory on the desktop.. drill down to applications, utilities.. drag it to your utilites directory.. or just run it. Do not run both utilities.. stick to the tool and leave the toys behind.
