Odd discovery on my iMac 20" w/ iSight

I've taken apart my 20" g5 w/isight (initially to swap out a hardrive), I know, warranty is shot. I discovered that there is a power re-set button on the backside of the logic board. I suppose since mine has power issues (and is out of warranty), I could drill an access hole so I don't have to take it apart to do a hard reset?
Thanks.

Unfortunately, the iSight models are _*not user repairable*_. Except for RAM installation, you must take the computer to your local AASP for all repairs and/or installation of parts.
MGW may have some posted links for HD installation for the iSight models. Search these fora if she does not respond to your posting.

IMac G5 w/iSight With A Weird Circle

I'm having an odd problem with my 20" iMac. I bought a new HDD and I'm not able to get to the desktop so I can install it.
It seems I've tried everything but so far nothing works.
Here's the problem:
no matter what key I hold down, or whether I have the HDD installed internally or externally, it starts right up and goes to the apple and spinning gear.
I'm using the correct start up disk for the iMac BTW. Anyway just when I think, all right here we go, I see a circle with a line through it where the apple was and I'm stuck.
There gear keeps spinning but nothing else happens and I have to shut it down. I've tried resetting the pram and using the option key key, which clearly shows the install disk which I choose, but again after a few seconds I get the circle with the line through it.
Do any of you have any ideas? Thank you!

Let us know how things turn out, and also, please put your model iMac (e.g. iSight) in your specs that appear at the bottom of your post, it makes things easier and helps us to make model appropriate suggestions.

I have recently upgraded my iMac Intel G5 iSight to OS 10.6.8 and now the internal mic does not work with skype or facebook. I can here static when playing back clips. Do I need to update firmware or reload old sys parts

I have recently upgraded my iMac Intel G5 iSight (iMac5,1) to OS 10.6.8 and now the internal mic does not work with skype or facebook. I can here static when playing back clips. Do I need to update firmware or reload old system parts. I have zapped PRAM. The blue indicator in system audio panel will appear for a second as I slide the bar for internal mic but then it disappears. Is there a fix?

The sound seems very faint but can here static on playback.

IMac G5 (no isight) power supply keeps failing

I had some trouble with my iMac G5 (no iSight) about 5 months ago with the power supply. I replaced the power supply, worked great for 5 months and now it's doing the same thing (turning off suddenly, trouble rebooting). I've done all the resetting of PRAM, NVRAM and SMU. Wouldn't start at all (white light would just flash) until I reset the SMU again. Didn't see any leaking items inside the machine like I've read about. I'm curious if anyone knows if I'll have to keep replacing the power supply every 5 or 6 months?? Could there be something else wrong? Thanks a ton.
RG

Did you replace the power supply yourself, or did you do it under Apple's Repair extension programs? You may still be eligible for free repairs if your serial number is correct.
In addition to a power supply problem, you could have dried thermal paste or a bad connection which would cause the same symptoms.

Graphics problem on iMac G5 w/ iSight.

I just tried installing a 1GB RAM stick in a 17" iMac G5 (iSight). The machine has 512MB of RAM (the standard), and a 1.9Ghz processor. It is running Mac OS X 10.5.7.
My friend, who owns the iMac told me she'd been seeing some weird graphics artefacts and had been having several lock-ups on the computer which required a forced restart to fix. I didn't know what to make of this and said I'd check it out when I went to install the RAM for them.
The problem alarmed me - rather than a few stray black lines that I had been told about, I found all of the following issues.
1. Black / White or Transparent lines on windows and toolbars. These were particularly predominant on menus and other semi-transparent parts of the screen, but also occurred on solid windows - such as Safari.
2. Blank screen - the screen would just go blank after a few moments.
3. Screen freezes - everything on screen would stop other than the arrow. Sometimes this would stick as an arrow, or sometimes as a beachball.
4. A really strange phenomena when I opened a browser page and suddenly the left of the screen slowly faded to black, while the right went white. This went in increments as I watched with the image of the desktop distorted behind it, burning out.
To try to fix the problem I took the following steps:
1. Reinstalled Mac OS X 10.5.7 Combo Update. This had no effect.
2. Repaired permissions. (I didn't expect that to help anyway)
3. Tried booting into a second user account on the computer (again, all the same problems were there - even worse on the other account in fact.
4. Unplugged all peripherals (no effect)
5. Removed the 1GB memory stick I had just installed - this appeared to fix the issue and I thought that maybe this was causing it. However, after a few minutes of normal operations, the problems all came back.
Just to clarify - the problems apparently started a week or so ago (this might coincide with the owner installing Mac OS X 10.5.7, but I can't be sure), at this point the computer only had its built-in 512MB RAM. With the additional 1GB RAM that I installed, the problems seemed to be worse. I know there is nothing wrong with the RAM as I had been using it in my iMac G5 up until this point.
I initially suspected the problem was the graphics drivers - as the problem occurred after upgrading to OS X 10.5.7, though I wondered if the problem could be the GPU itself?
However, I am now wondering if it's a RAM issue as additional RAM makes the problem worse - would having more in the computer change the way that the internal RAM is being accessed and mean that the end addresses of the built-in RAM are being accessed more quickly when additional memory is installed?
I was unable to find out if the machine would work alright if booting from the Leopard or original install Tiger DVD - as I didn't have time to check these.
Please advise me what I can do to diagnose the problem further, or what the owner can do to fix the problem.

"I will have to dig out my copy of Leopard or the original installer for my iMac G5 (w/iSight) as the owner doesn't know where her copies have gone! Maybe trying these will help find a solution"

any ideas what do you think thanks for help.

If the seller proclaimed that he/she was selling a working computer, strongly suggest that you get your money back. You don't know what could be wrong nor the real condition of the computer.
Macs are not suppose to be sold w/o the system DVDs that originally came w/the computer. You will need to obtain them from the seller. System DVDs are machine specific and cannot be used from one computer to another. You also need them for troubleshooting as one of them comes w/the Hardware Test.

IMac 17" with isight RAM question

I want to expant RAM on my old iMac - iMac 17" with iSight, 1.9 GHz, introduced october 2005
Is this RAM module going to be compatible?
DDR2
*2 GB*
*533 MHz*
PC4300
1,8V
*240 pins*
*Cas Latency: 4*
My concern is if the certificate (PC4300) is going to be compatible. Apple website says that there should be certificate PC2 4200.
Thank you for your answer. Greeting from Czech Republic.

Welcome to Discussions - the specs for your memory are
iSight:
1. PC2-4200
2. unbuffered
3. nonparity
4. 240-pin
5. 533 MHz
but I think the 4300 would work, just make sure that you can return it if it doesn't and that you get a lifetime guarantee.

IMac G5 17" iSight display problem

Hi - I have an iMac G5 17" iSight. Specs are 1.5 Ghz G5, 2.5 GB RAM, 150 GB Hard Drive and SuperDrive. The Hard Drive is wiped clean, I boot it with an external FW drive running 10.5.7.
Here are the issues: As soon as the machine boots, the LCD shows 3 permanent vertical lines on the screen. This is as soon as it displays anything, from the initial Apple logo all the way until shutdown. While it is on and booted up to the desktop, it runs fine, except sometimes it will randomly refresh the screen or change resolutions. These are the only issues.
While I am quite sure it is one of three things (inverter, video cable or LCD), I still took the typical troubleshooting approach and tried any quick fixes I could. These included-
1. Boot off of known good OS
2. PRAM Reset
3. SMU Reset
4. Reseat RAM
All of these had no effect. From there I tried two more things-
1. External display via mini VGA
2. Ran Apple Hardware Test
3. Ran LCD tester
The external display worked perfectly, which tells me that it isn't the GPU/logic board. I ran AHT and the logic board passed both quick and extended tests. During the extended test I got an error for the ATA bus/drive, but I haven't looked up the error code yet. Everything passed in the quick test. I used the LCD tester, which puts solid colors on the screen (Red, Green, Blue, White, Black). The 3 lines run across the whole screen vertically, and cannot be seen on a solid white screen. On the solid black screen they show up yellow and purple.
Here is a screen shot showing the three vertical lines-
http://i3.photobucket.com/albums/y93/thisismymind/untitled.jpg
I was wondering if there is an easy way to diagnose this just by looking at it. I was figuring replacing the inverter and/or the video ribbon cable first before replacing the LCD... but if anyone here can diagnose it easily than that may save some time.
Thanks in advance!

Imac G5 (pre isight). Mass Storage Error

I have an imac G5 (pre-isight). Using Tiger. Recently it has been playing up. Two main problems: starting up and waking after sleep mode.
*Starting up issues*
There doesnt seem to be a consistent problem here. Sometimes it hangs on the grey apple screen, sometimes grey probitory sign screen. Sometimes it hangs on a black screen with white writing. On about the 10th to 20th time of rebooting, it seems to startup and work fine.
*Sleep issues*
If I leave the computer to go into sleep mode, it tends to freeze in whatever application is open. Especially Safari.
I have tried numerous fixes. I've reset PRAM, done the SMU thing. Repaired and verified disk many times. Repaired and verified permissions. I've archived and installed and archived and erased. There's barely any software on here apart from the operating software and MS Office (legal). I'm using an apple keyboard (wired) and a wired mouse. There's no important info on here so am happy to wipe everything.
Finally i did a hardware test and received a "mass storage error" (only appeared for the extended test)...
2STF/8/3: S-ATA Bus 0 –Master
Having looked up several forums i replaced the hard drive. (Made sure it was compatible, similar size and same specs as original). Reinstalled software and got all the latest updates. Seemed to be working quite well for a day or so, although there was a few 'permissions' error which seemed easily fixed.
Today i awoke the imac and it had frozen. Back to it's old tricks. Tried restarting and got grey screens, black screens etc. Repaired permissions. Ran another hardware test and getting the same error message about mass storage!
So if it's not the hard drive, what's wrong for my imac? Is it time to just dispose it?
Thanks in advance for any ideas you may have.

The recall ended many moons ago, and it's a capacitor problem, they all need replacing, those in the power supply as well, probably.
If you are handy with a soldering gun, have steady hands and are good at repairing electronics, you can do it yourself. Look at [welovemacs.com] or [synaptech.com] for parts and advice.

IMac G5 17" iSight No keyboard/mouse

I have a 17" iMac G5 w/ iSight (1.9Ghz). It boots up but loses the ability to power the keyboard and mouse at log in. Actually, I can get the mouse to light up if I plug it directly into the computer, but no control of the cursor.
Any suggestions or advice? Thanks in advance.
Sean

Two things, first, reset the SMU and then, if you can connect to the keyboard, reset the PRAM.
If that doesn't work try using Target Disk Mode to run Disk Utility and repair the drive. Try to borrow another keyboard and mouse and see if they work, also, try logging in on another account and see if you can work that way.
Please let us know how things work out,

Final Cut Express + iMac G5 w/ iSight

Hey everyone.
Would Final Cut Express v.2 work on an iMac G5 with iSight. I know that certain versions of Final Cut Pro won't because of the video card incompatibility, but is it the same with Express?
Please get back with any responses you feel helpful.

Hi Jason.
Your Mac has a PCI card instead of an AGP one which FCE is designed to use.
There is a workaround for G5 Macs with PCI cards and also Intel-Macs that some people have been able to use.
There is no danger to your computer because you are not altering anything other than 3 letters in part of the FCE code. There is also no risk to FCE because even if the worst should happen, the most you would have to do would be to re-install it:-
1. Right click on the FCE icon and select "Show Package Contents".
2. Open the "Contents" folder and double click the "info .plist". It should open automatically in TextEdit - if it doesn't, choose TextEdit manually.
3. Around 15 or so lines down you will see AGP. Delete it and put in PCI.
4. Close the window and when asked if you want to save the changes, say yes.
You should then be able to open FCE and use it normally. (On Intel-Macs it may well work slowly).
Ian.

IMac G5 (w/iSight) running slow and hot on web browsers

Hello-
I've had my iMac for 4+ years and haven't any problems I couldn't fix on my own until now....
Machine is an iMac G5 w/ iSight with all original hardware except an extra 2GB of memory (for a total of 2.5). Over the last couple of months, my web browsers have begun to run slower and slower (mainly Safari, but I also use Firefox). Also the processor fan (I believe) comes on more quickly and frequently. It is now to the point that anytime there are any imbedded graphics, whether it's a youtube video, or a weather radar loop, or my kids are on webkinz, the fan kicks in and the top left corner gets extremely hot to the touch. As soon as I leave the page or close out the browser, the fan dies down. I cannot run any of these sites optimally. I am also getting quite a lot of page loading errors in Safari such as "Safari can't find the server." However, when I hit refresh the page comes right up. There does not seem to be a pattern to these messages. This only seems (so far) to be an issue with the browers. Today I simultaneously played a DVD, played songs on iTunes, and work in MS Word. No fan...
Here's what I've done so far:
Repaired disk permissions
Ran the extended hardware test (passed, no errors)
Ran diagnostics on my network connection (passed)
Reset Safari and Firefox incl. clearing the cache and deleting all cookies
Ran cleaning and maintenance w/ OnyX
Any thoughts or help would be much appreciated!
Thanks...
JD

Which Camino? Do you have the latest, which I think is 2.0.3? It's difficult to pinpoint why all your browsers might be slow to load.
You could try the Servers from OpenDNS which may be faster (and safer, since they are patched for DNS poisoning/redirects) than those of your ISP. Put these numbers in Network> DNS for the interface your are using, eg. Ethernet, Airport:
208.67.222.222
208.67.220.220
Then check to see if it's working by going to
http://www.opendns.com/welcome/
You can also test your speeds here
http://www.speedtest.net/
Here's something to read on slow browsers (in this case, Safari, but applicable to any browser.)
http://reviews.cnet.com/8301-13727_7-10354948-263.html
If the refresh option works quickly, that might indicate that your Internet speed is slow. Once you've been to a page, it's stored in the browser cache, so it doesn't need to reload everything from scratch. I don't notice any difference in speed from refresh loading, so I suppose my Internet speed, though only around 1MBPS, is fast enough not to have to depend on the cache.
I don't know for certain if that indicates a problem, but the CPU spiking temporarily to 100% on loading a page doesn't sound like a big problem. Your processor is by now relatively slow compared to newer machines and web pages are getting more complicated with more elements to load all the time.
Finally, those G5s do run kind of hot; it will only delay the arrival of the hottest temps, but putting a fan at the back does help a little. I use one even on this new iMac.

IMac G5 w/iSight freezes up with distorted screen

I have a 20in iMac G5 with iSight and it isn't even six months old yet. At least once a night the screen turns goofy, not really pixilated but kind of crosshatched. (usually from the bottom - up) The mouse still moves but nothing is clickable and I can't get to my dock. Force quit doesn't work and I am forced to restart. I thought I had it narrowed down to two applications that caused it, but last night it froze up while re installing software and listening to iTunes.
As you can tell from my name I am a convert from a pc. I work on both a mac and pc for work and I haven’t had a problem with the Powerbook at all. I love it. I wish I could say the same about my own machine. Currently, I find the new commercials ridiculous with the pc constantly freezing up and the mac is fine. My pc didn't freeze up half this much. I am frustrated because I just lost my recent work for my final project for Grad school and I could have thrown this thing out the window last night. Can someone please help with my frustrations.
The Convert

No it was an "Recognized by Apple Computer, Inc. as an Apple authorized reseller with demonstrated expertise in providing consultation and service for Apple computers." That quote was taken right from their site.
I thought the same thing as you. There was no way it was a font but I am relatively new to troubleshooting on a Mac so I didn't argue.
This is the place where I brought it and I don't ever recommend anyone else go there - http://www.macpros.biz/
Have any other ideas? I am stumped. I don't really want to take it back there when
1. I know just as much as they do.
2. They charged me $63 to tell me they couldnt find a problem. How much are they gonna charge me to keep looking?

Is iMac G5 (no iSight) harddrive interchangable with Intel iMac (white)?

I have a new (used) Intel iMac, and I'd like to put the harddrive from an iMac G5 (no iSight) into it. Do both these computers use the same type of harddrive? Can I just swap them? Thanks.

I have recently done the same thing with no problems. They are both SATA drives, so there would be no problem with the system recognising them, my only concern because of the "close to the edge" limitations regarding iMac power supplies was whether the larger drive would draw too much current and exceed the safe limit for the system. I checked with the manufacturer's web site and they both drew the same power so there was no problem. I went from a 250GB to a 400GB drive.

Screen Problems with iMac G5 20" (iSight)

Hello!
I had the same problem with my iMac G5 20" (iSight) as described by Bob North Apr. 18, 2006 at http://www.macintouch.com/readerreports/imacg5/topic2276.html#apr25:
"""" I repair Apple products, and recently I've seen strange and erratic display problems with the G5 flat-panel (iSight) 17" and 20"...and I am very curious about the origin. The picture will display what I will call "plaid pixles". Upon boot, the dispaly appears normal, but within 5-10 minutes, either at desktop or in ASD, the normal display will "crash" to the "plaid" display. The desktop, or whatever, can still be distinguished in the background, but it is overwashed by the plaid patterns -- which do change slightly, and also cover the full space of the screen. I've seen different scenarios, 3 in 2 weeks, where the symptom is exhibited with no particular failure pattern -- both before and after repair. I've replaced the main logic on one occasion, with no fix...but the 2nd try replaced both display panel and inverter. The display issue was fixed, but the system exhibited lockups only when it reached the destop. Another repair the same issue was seen after replacing the 20" main logic, where the symptom was not present previous. Personal opinion of the late 2005 IMAC flat-panels, in the hardware sense, is the likelihood of component manufacture issues, possibly the main logic boards or the panel displays themselves. Repair of this model, as opposed to the earlier, non-iSight flat-panel 17 and 20" models are extremely difficult -- access to main componenets is blocked by the display panel, which must be removed for each troubleshooting attempt. The internal hardware design is not oriented for repair ease...they are by far the most difficult to work on.
Any input regarding the display issues? Thanks.""""
I can't use the mouse or anything else, and after a while the fans start to go on max. This is the second time I encounter this problem within 30 days. What I have noticed is that the day before, the brightness of the screen started to "blink" slightly -- like if the screen tried to adjust itself.
But I haven't experienced what Bob North describes as the: "Upon boot, the dispaly appears normal, but within 5-10 minutes, either at desktop or in ASD, the normal display will "crash" to the "plaid" display".
I just restart with the power button and everything is working OK. I made an Extended Hardware test without any problems detected.

Does it look anything like this?
http://downwardspiral.net/gallery/pbg4-display
My nearly 3 year old Titanium PowerBook G4 just did this one day, out of the blue. The problem went away after a few minutes, but I had already taken photos. Thanks to those photos, Apple gave the powerbook a new logic board.
(This PowerBook has had its logic board replaced twice, a new optical drive, and a cracked case edge replaced. AppleCare has more than paid for itself. Despite the occasional problems, I remain very happy with this machine. I'm sure I'd be much less happy if I had not bought AppleCare!)
