Did we kill our flat panel

my wife's 17- usb2 flat panel was having occasional crashes, so it occurred to me that it could use more ram. I didn't feel like opening the bottom, so I bought the computer to a repair shop that works on macs. he put a stick of kingston memory in the factory-installed slot bringing up to 1 gig. we brought the computer home and turned it on. It was fine for a half hour when it suddenly went dark (not asleep, dark). We restarted and got an "Open firmware" window and a graphic that looked like either scribble or a thousand computer chips. I restarted and heard a squeal (like a high D), then got the open firmware window. A few restarts later, we got the computer running, but there were odd lines through the screen.
at that point, I shut it down and opened it up and replaced the ram back to the original, carefully using my torx screw driver. I closed it up, turned on the machine and it worked fine — for twenty minutes when it went dark and this time refused to wake up.
I opened it again and rechecked to make sure the ram was slotted. it was. turned it on, got the chime and nothing, as if it won't access the ram or anything. I don't hear the disk drive turning, just the hum of the machine. I tried command option O-F (someone had success with that), but no luck.
anyone have any suggestions? Is this computer toast?
thanks for any advice,
jeff

Take it back and have that stick removed, the new RAM. Sometimes bad RAM or incompatible RAM will do that. Worth a shot.

Wireless connectivity with iMac G4 flat panel

Hey everybody,
We are thinking about buying an airport card for our imac G4 flat panel. We live in Ireland and are in the process of switching from a satellite dish-based Internet provider (connected via ethernet cable from the roof through the wall to the iMac) to our cable TV providers for a less expensive connection. The cable modem will be up in the TV room (the only cable CATV point that works), where we will attach a wireless router that will allow Internet access to the iMac downstairs and the iBook anywhere else in the house. Our cable providers offer 1, 2, 3 and 6 MB download speed packages. Here are the questions:
1) Is the "Apple Part No. M7600LL/E" available on macwireless.com the right one for our flat panel iMac G4 from 2003?
2) Is there any advantage to the airport card versus using a bridge? If so, which bridge is appropriate and easy to configure?
3) Which wireless router is recommendable to link with the cable modem upstairs?
4) Will the connection be strong enough between the router and the airport card or bridge to provide full speed and, possibly, VoIP (saving dough to one day be able to upgrade to a 20-inch iMac! LOL)? The distance is about 8 meters.
5) If we later upgrade to a new iMac and give our son the flat panel will everything still plug and play?
6) Which download speed package do we need to make everything run smoothly?
7) Is it really feasible for a "layperson" to install the card themselves?
Thanks again for your help!

Forgot to say in my other post. There's no need to buy at that price ($199) and pay for shipping - there are plenty of UK/IE options for buying.
There are also alternatives like Ethernet over Mains electricity (14 or 85Mbps) which may be a better option than original Airport.

Upgrading Imac g4 flat panel 800 mhz

I decided to post this information here because a lot of people are wondering how do i go about upgrading a macintosh imac g4 A.K.A Ilamp as it is known in the mac community.
Well this tutorial will walk you through a basic configuration that i recently did that seem's to work very well.
Item's you will need.
1. mac os x tiger 10.4
2. A external cd-rom/dvd-rom
3. a 7200 rpm 250 gig hard drive
4. 1 stick 512 meg's pc133 sdram
5. 1 stick 512 meg's pc133 so-dimm for laptop memory slot at base of imac
6. a new and faster dvd-drive (i used a light scribe)
So after installing all of the hardware in my imac.
I ran into a problem it has to do with the imac firmware update for mac os x tiger to be installed..
The built in dvd-drive wouldn't eject i thought it was a bad drive come to find out the drive won't eject without a os on the machine.
so i needed a external usb/firewire cd/dvd-drive to boot the tiger installation and install tiger well after installing tiger from the external cd/dvd-drive i noticed the drive ejected and worked fine but i knew that if i wanted to burn anything i would need to install a new drive.
so i purchased a new lightscribe drive.
installed it.
after that my system specs are
Imac g4 800 mhz
1 gig ram
250 gig hard drive
52x lightscribe DVD
running mac os x 10.4.11
it really just depends on how much you want to spend to upgrade i found that this configuration works great for media streaming.

what kind of HD did you get for it? I'm still waiting on buying the right one. version that can be installed in these older lamp macs of ours. I know it needs to be an IDE drive. Is that the same as an ATA drive? i know that the new systems now are SATA.i happened to call apple one day and they said that my G4 flat panel uses ATA-6 drives. i do a search for those drives on newegg.com and all that comes up are notebook drives. so what kind of HD do i get?

Mixing RAM Speeds In iMac G4 1GHz 17" Flat-Panel?

I'm just checking here.
I have an iMac G4 1GHz 17" Flat-Panel, Model M8935LL/A (USB 1.1 version) that currently has the standard 256MB PC2100 (266 MHz) RAM module installed in the factory slot, and a 512MB PC2700 (333 MHz) RAM module installed in the bottom (user-accessible) slot. I bought the machine direct from Apple, so despite the "official" spec (which calls for PC2100 RAM in both slots), it's obvious that Apple knows PC2700 RAM will work in that machine. My understanding is that the faster PC2700 RAM simply downclocks to accommodate the lower 266 MHz bus speed of the M8935LL/A. As I understand the DDR SDRAM spec, any DDR SDRAM (PC1600 through PC3200) module will simply overclock or underclock to accommodate the host bus speed...but feel free to correct me if I'm mistaken on that point.
I'm fixing to upgrade the hard drive to a larger capacity model. I've done it before, so I know it's no picnic. Since I have to go past the factory RAM slot anyway to change the hard drive, I figure I might as well upgrade the internal RAM to the full 1GB limit. (Yes...I know Apple says you can't exceed 512MB in either slot, so please—no remonstrances about sticking to Apple's spec. The spec is wrong.)
Obviously, it's possible to mix the two RAM speeds between the two slots, since Apple shipped the computer that way. Here are my questions:
• Is there any downside to going the other way when I upgrade the RAM—that is, putting a 1GB PC2700 (184-pin) module in the factory slot, and a 1GB PC2100 (200-pin) module in the user slot? The reason I ask is because my preferred supplier (OWC) can't supply me with both modules in the same speed.
• Is there any performance advantage in both modules being the same speed—that is, both PC2100 or both PC2700? If not, I'll just buy the one of each speed that OWC has available.
Thanks!

So, you know have 2Gb available in your flat screen imac?
Yes indeed—2GB confirmed as available by Apple System Profiler. Both modules are PC2700. Everything is working fine.
I guess I can understand why Apple discourages users from replacing the 184-pin "factory slot" module. There's not a whole lot of slack in the motherboard connector cables, so it's best to disconnect them in order to get the bottom section to lie flat on the workbench. I suppose some folks might be hesitant about disconnecting things, but it's really quite simple, and involves only three connectors. After having changed the hard drive a few years ago, replacing the RAM was a piece of cake by comparison.
A word of caution to anyone who's going to attempt it, though. There are TWO heat sink interfaces between the bottom section (where the motherboard is mounted) and the top dome. Those heat sink surfaces are coated with thermal paste at the factory, but the compound dries out over time, becoming a rubbery membrane between the heat sink surfaces. Once you separate the top and bottom sections, the membrane rips apart, and the firm connection between the heat sink surfaces is permanently gone. It's a bad idea to simply put them back together after you change the RAM module; you won't get a good thermal connection.
The solution is to scrape all of the old rubbery compound off all four surfaces (two on the bottom and two on the top section). I did it with a piece of PVC, but you can use anything with a sharp edge that won't scratch the metal surface—even your fingernails will work, unless the old compound has dried out to the point where it's hard. After you scrape the old gunk off, apply new thermal paste to all four surfaces.
The other maintenance item you can perform while you're in there is cleaning out all the dust, which accumulates in vast quantities and interferes with cooling. I vacuumed it out with a plastic crevice tool, being careful NOT to touch any of the components with the tool. Vacuuming can build up a static charge on the tool, especially in dry environments, and high static voltages aren't friendly to microprocessors. I used a securely grounded anti-static wrist strap throughout the entire operation, and even wrapped it around the vacuum tool.
Good luck!

Mac Mini to G4 iMac Flat Panel display ???

Just scanned some pages back in this forum and couldn't see this as a topic-so I'll ask.
I was wondering, if I had a 17" Flat Panel imac (even the 800Ghz version, or the 1Ghz or the !.25Ghz - or event the 20" [yummmmy] ) could I drive the mac mini via the iMacG4's highly versatile flat panel display ???
[ideally I'd love to be able to re-engineer the Flat Panel's guts with smaller but faster CPU etc - and as machine innards get smaller maybe this will be possible - because the screen tilt and swivel is so versatile; eh!)]
gregg

Hmm - why did myinnermostthoughts sudenly become a hyperlink - or is it a hyperjump into the final frontier of cyber-computing???
Anyway, but I had hoped to just plug a keyboard into 2005 'Twiggy" , use a VGA adaptor/er between the two machines, and use the 1.42 Ghz speed of the 'Twiggy' to display stuff (CS2 etc) on the Flat Panel's display (oxymoronic word usage here - I suppose). The Flat Panels do have an vga port - so why cant the cable go from the mac mini to the VGA port of the iMac ??? Are you saying ti's almost impossible - or are you refering to re-engineering???

17" flat panel Mac can no longer get on my Airport Extreme network

My 17" G4 flat panel iMac can't get on my Airport Extreme network. It has been on the network for years. All of a sudden I can't get on my own network. The Airport extreme uses a WAP2 Security password. Everything else in my home is on this network ie. Blu-Ray players, Wii, Nintendo DS's, MacBook, Apple TV. The G4 doesn't even have WAP2 as an option! Where did the option go? I really don't wanna set up the network again with a WEP password(That's an option on the G4) and have to reset everything. What happened?

There were two 17" flat-panel G4 iMacs. The earlier of the two (Part# M8812LL/A) had an optional AirPort Card. This card only supports 802.11b and either the WEP or WPA security standards. It does not WPA2. This may be the reason the G4 is not able to connect to your wireless network if you have it configured for WPA2 Personal.
You will need to reconfigure the AirPort to use the "WPA/WPA2 Personal" option.

Mac will no longer turn on - iMac G4 (Flat Panel)

I have an iMac G4 (Flat Panel) that will not turn on. I've tried to obvious things such as changing the power lead/fuse etc., but this hasn't solved it. If you hold the power button in you can hear a faint 'ticking' sound coming from inside the Mac, but it doesn't power up. I'm guessing something more serious has 'blown' inside, but I have no idea whether it's a lost cause, or something that could be easily fixed. Any ideas?

Hello Matt,
I have the same problem you describe. You may want to try what I did to bring the iMac back on. I just leave it alone for a day, with the power cord disconnected. Then I try my luck by connecting the power cord back and start up again. Some patience is needed here as I am successful only after half a dozen of retries. I also hold the power button until I see the lights on the mouse comes on.
Once ON everything works fine..software restart is not an issue either..just dont shut down..then u may have to to wait another day to try again..I was lucky four times and did this in the past week. ..can be frustrating but lucky i still have the G5 to use.
I dont have the proper solution to the problem and still trying to figure out what is the cause..I have reset the PMU (see apple support website on resetting the PMU) but the problem still remains. Another forum participant suggested to change the internal battery (an inexpensive exercise) but Apple website advice us not to do it and let them do it..but I will likely try to do it myself later.
For the time being, hope you can start up the machine like i did.

G4 Flat Panel power problem

Hi
We recently had a power cut and since then I have been unable to start up our imac flat panel. We have tried the fuse, plugged it in somewhere else and checked all the leads etc, but hold the power button on and nothing. I changed the PRAM batery about 3-4 years ago and have not had this problem before this occasion. Does anyone know if there is an internal fuse or a reset button etc

The reset often tried after a power outage or other interrupt, requires one to follow instructions in the maintenance support article regarding a reset of the Power Management Unit (PMU) as follows.
•Resetting the iMac (flat panel G4) Power Management Unit (PMU)
http://support.apple.com/kb/HT1712
This article has a few helpful images of the computer and basic explanations on how to do the procedure.
Other more in-depth items may require more take-apart know-how and techniques which will be more tedious and would follow instructions such as those outlined in an official iMac G4 Apple repair manual in PDF. These may be hard to get. While I have three iMac G4 17" 1.25GHz desktop computers, none of them are up and running at this time; my original one has a power issue and I believe it may be a failed power supply. Of the other two, one was acquired as non-running parts computer, but it has a good power supply, optical drive, display, and a few other parts. The third iMac in my instance, needs a replacement optical drive; so while I have three of these, all of them would require disassembly to remedy their various issues.
When you take apart one of these, be sure to have some new Thermal Paste, a new/fresh clock Battery, a means of re-torquing the internal chassis to required specification, and remember to remove all the old thermal paste from the heat transfer conduits before re-assembly. If you can get the correct Service Manual for this iMac G4 (several in series) which was an official Apple document, in PDF, it would be of great help in troubleshooting the issues. Some of the suggested repair procedures require access to known-good parts; in part to swap out and help find out what is not wrong with it.
Online sources of information vary, as do their worthiness and value as problem solving tools, depending on depth of the troubles involved. Even a site with info such as this iFixit may offer tips for some situations: http://www.ifixit.com/Device/iMac_G4 -- And the xlr8yourmac article on how to Take-apart iMac G4 for Drive and Ram upgrades has a few others: http://www.xlr8yourmac.com/systems/imac_g4/imacg4_takeapart.html
There are test ports or holes under the first bottom plate cover on the iMac G4 where one could use a multimeter and small tipped probes to check for correct voltage outputs from the computer power supply. There is a chance one of the power supply transformer voltage outputs may have failed.
Sometimes, a power failure may coincide with other parts failures; in example, a hard disk drive on its last legs may be affected by a power surge or outage timed upset, and that contains startup disk OS files.
To find a qualified and trained technician who can and will help repair these older models, can be a problem in and of itself; several shops also sell new hardware and their answer for an old unique computer, is to get a new not-so unique model from them. With the correct Service Manuals, you could eventually repair one of these, if you can get good quality replacement parts at low cost and do the work yourself.
Hopefully this helps somewhat.
Good luck & happy computing!

G4 flat panel crashes constantly!

About two weeks ago my G4 flat panel started crashing intermittently. Half the time it just would not start up again until it had been left for a while. Thinking the hard drive was overloaded, I backed up all my files and did a clean install of Tiger. (It now has 27 Gigs available.) It was fine for a few days, then it crashed again yesterday! I reset PRAM and NVRAM. I switched off the sleep option, thinking it might be causing the crashes. Then, this morning it crashed again This time I was able to copy this information:

You may have to try removing the RAM upgrade, and while the computer
is still off, put it back together, put the power cord back in, and then try
and reset the PRAM on startup. That's the old four-finger salute where
the option, command, r, p keys are held down almost forever after press-
ing the power button with the four held down. The computer should make
a startup bong sound, then keep holding the keys down until it bongs thrice.
The RAM chip may be bad; but then too, could be an issue elsewhere in
the computer. There is a good troubleshooting topic on how to go about:
Resolving Kernel Panics:
http://www.thexlab.com/faqs/kernelpanics.html
Technical Note TN2063: Understanding and Debugging Kernel Panics
http://developer.apple.com/technotes/tn2002/tn2063.html
The issue can mean a hardware issue could be the cause; or it may
mean there could be a software cause behind the kernel panic. In a
few cases, there may be a combination of both; so troubleshooting
is a step by step process. Simple things, such as the RAM, first.
In some situations, the problem may be more or less involved; you
can hope for a less costly cure, but if it gets too odd, you may have
to pay a tech to troubleshoot. If you have skills in this matter, you
should be able figure out how involved this one really is...
Good luck & happy computing!

Installed airport card into my imac G4 flat panel and now it work

I purchased an airport card from Mac-pro as Apple does not sell them anymore. I installed it into my IMAC G4 flat panel as per the instructions. Now, when I turn on the computer the power light comes on, and the screen is black and it really isn't making any noise, as though it is not starting up. It was working just fine before I installed this card!!!! can anyone help??!?!?!?!?

The following Apple article provides the details of
installing an AirPort card in the Flat Panel iMac
G4s. You may want to double-check it to see if you
might have missed something in the the installation
process.
I installed the card properly, as per the instructions you forwarded to me. I did have some trouble getting the card to completly fit into place, one side seemed to go in easier than the other, but it did go in. Is there anyway to get this machine up and running again?

Urgent - iMac G4 Flat Panel - Is Adding Monitor or Flat Screen TV Possible?

Hello,
As a present to my husband (mac guru) I would like to know if with his iMac Flat Panel G4, is it better to buy a 28 inch samsung computer monitor (flat panel) that he can also hook up his mac to or a kind of flat screen/panel LCD TV. The guys at futureshop and bestbuy seem to be "confused" when talking about macs and not pcs. With the computer monitor, there seems to be questions on if we'll be able to hook up our satellite tv... and with the tvs, there seems to be confusion on if we can hook up the computer. One of the reasons I want to hook the computer directly is my husband has had problems converting (burning to DVD) some videos with music background from iPhoto without doing a software update which requires us to change the timing with the audio and video in our already created slideshows. Please help quickly as some sales finish tomorrow. I need to know what to tell the store... i.e. what kind of jack or cables or capability I am looking for. Do I ask for USB port, coaxil input or what? Thanks in advance,
Karen

Yes you can connect a display or monitor but exactly which ones depends on which iMac G4 you have.
All iMac G4s have a Mini VGA port this will allow you to connect any standard PC Monitor (with a VGA connector) and mirror the iMac's internal display only. The later iMac G4's also allow the connection of S-Video and Composite Video devices (most TV's have this type of input) which allows you to mirror the display on to the TV.
The MiniVGA to VGA and Mini VGA to S-Video/Composite adaptors are for sale online in the Apple Store ($19US/£15) or here.
If you wanted to extend the screen size again it is possible on some iMacs but requires a firmware hack that will invalidate your warranty.
I can't understand how having an external display will solve the burning to DVD issues though.....
Post back with your Screen size and processor speed for exact info - or read this recent post

IMac G4 flat panel update

just got a 17" iMac flat panel, the moderne white one with the ball bottom.
It's running system 9 right now, it did not come with any disks.
what steps would I need to take to get it updated as far as it is possible to go?
how many systems disks would I have to go buy and go thru? I have a tiger update disk but that's about all I have.

IMac G4 Flat Panel 1Ghz - 1 beep when turning it on.

I have an iMac G4 Flat Panel 1Ghz that beeps once when you turn it on. After doing some research, I learned the 1 beep could be no RAM or RAM problem. I replaced both the internal RAM and the easily accessible RAM with RAM from a reputable dealer that markets this RAM just for iMac G4s. I still get one beep after startup. I tried taking one stick out and all variations of using the old and new RAM with no difference. I did more research that maybe it was the power supply. By the way, originally this iMac was shocked through its Ethernet port with lightning. I since bought a new motherboard, new RAM as stated, and now also the power supply. After putting it all together, I still get one beep at startup. I have reset the PMU also. Also added a new battery. Looking forward to your suggestions.

There may be some indication of the beep's cause after some thorough
testing of the computer with some utility software; perhaps even the basic
Apple Hardware Test which would have accompanied the computer when
new could be helpful to some degree, if the machine were run in that, in a
long continuous loop to see if at some point, it may generate some codes.
However, the startup sequence itself is where such a hopeful bit of information
would more likely be generated; and this is the kicker, in that some of the info
at start-up is too early in the beginning of the run-cycle to be recorded or read.
But, you may find evidence of the issue in the Console error message reports
in that utility; and there are a few different sub-titles of places in Console to look.
Also, you may be able to find some error or crash messages, or other runtime
messages and glitches, in the System Profiler> Software> progression path.
There may be another source of the single-beep on startup tone. Not sure of
any other, though; since the Power-on self-test is generally what checks out
those computers on start-up. And the 'single beep' suggests there is a RAM
issue, as this Beep would replace the normal startup chime.
So, that early in the startup, and without a booted system, the error logs or
crash and failure reports would not be generated to be read later.
Is the computer you have really a 20" LCD and does it truly have a 1GHz
CPU? Or, does it have a 1.25GHz PPC processor, as it should? Did the
company you obtained the replacement logic board from, have anything
to say about the kinds of issues you've noted the computer displaying?
There may have been a limited duration warranty on the rebuilt board.
There have been a few of the old iMac G4 17" & 20" 1.25GHz models
generating an odd, single 'buzz' sound after the normal startup tone.
Is your's making a 'single beep' or a 'buzz' sometime after booting?
Do you have any other RAM chips of correct supported version to
replace one or both RAM slots, of reliable quality product? How was
the OS installed into the computer, or have you been unable to do so?
Once in a great while, new correct RAM could be bad on arrival. Rare.
{This is a lot like chasing gremlins or setting a trapline for gnomes.}
Maybe someone, such as the contributor alias 'spudnutty' may know of

Can not burn or read dvd/cd's on imac g4 flat panel

Hello
Just recently I am having a great deal of trouble burning dvd's or cd's. If I manage to get a dvd or cd to burn(which is very rare that I do manage to get them to burn) they will no longer mount on my computer after I have ejected them from the computer. I get the same result wether using toast or the Disk Utility. My local Apple reseller sugested the drive was ok but had a coruption in the software. So I did a full and complete wipe of the system and freshly re-installed teh whole system. I am still getting the same problem.
The error messages I'm getting are "medium error xxxxx" or can not calibrate lazer level.
I have cleaned the dvd drive and I have made sure all disks are clean before using.
So any help would be appreciated.

check out the screen I get when I hold command at startup, what does this mean? none of the keyboard buttons respond to this or the mouse, except the return key which brings me back to the grey screen hanging forever.

Supported flat panel displays for an ATI Rage 128 Pro/G4 500

I originally was using an Apple 21" CRT display with my G4/500 until the display's picture tube failed. I am now looking to purchase a flat panel w/DVI, using my G4's DVI video port and the Rage 128 Pro card. I have found conflicting information on resolutions supported by the ATI card. I am looking at a Dell UltraSharp 2005FPW 20.1-inch Wide Aspect Flat Panel LCD, and the requirements indicate that my system must be able to support WSXGA+ resolution (1680 x 1050). A 24" version of the Dell monitor requires the support of WUXGA resolution (1920x1200). WIll either of these flat panel monitors work with my G4? If not, what specs do I need to look at to determine compatibility? Thanks.
Apple G4 500 Mac OS X (10.3.1) ATI Rage 128 Pro Graphics Card

Hi JBernstein,
Karl,
I greatly appreciate your efforts to resolve my
question.
No worries, Mate!
To address a question you posed earlier, no, my G4
did not come with a ADC port. I have both VGA and
DVI-D ports on my G4/500 (Graphite) with the Rage 128
Pro ADP card, which is 16 mb and 2x.
From that, I would infer that you computer is not ADC enabled.
It was the Genius at
the Apple Store who mentioned the Radeon 9000 card as
a replacement. but he also suggested that the current
20" Apple display would work with my G4 ... we tried
that today, and the OS would not launch and power the
display. SO, we must replace the card, or live with
small displays.
Yes, the ATY 128 Pro generally does not have enough grunt to power the larger displays.
I did find a number of Radeon 9600 Pro Mac Edition
video cards on eBay, but most had a published spec of
4X, and the response to whether it was backwards
compatible with the 2x capability in my G4/500 is
that it will not work. Is that true?
All the information I have (via the ATI website) does not specifically state that the 9600 card will support AGP 2X. Other ATI cards that do support 2X have this specifically stated in the information. Therefore, there is no garauntee that the 9600 card will support 2X. Until I receive information that someone has used this card in an AGP 2X computer with success, I cannot advise trying to use it.
I have not
confirmed the Radeon 8500 as yet, but as you might
imagine, it is frustrating to get conflicting
responses.
The ATI Radeon 8500 will work in your computer (as, partially, will the 9000 - refer to my earlier posting).
Perhaps you might address a different question ... is
there any place within Apple that I can go, even with
paying a fee for services, that would definitively
provide an absolute solution to an upgrade type
question, complete with exact part number AND
guarantee that the information is quite accurate? Why
wouldn't Apple provide some type of infomration on
replacement/upgrade path for older products (geez ---
the G4/500 Graphite isn't even on the legacy products
list yet) so that the customer can invest and upgrade
without going through a challenging process to get
the right information? The information I've turned up
is vague and not geared towards solutions like this.
Apple, for all sorts of reasons (legal and commercial), is loath to provide "official" advice on the use of any third party upgrade hardware on their products. Moreover, discussions on the morality of this is probably against the terms and conditions of this discussion forum.
I'm all ears as to how to move forward with this G4
with a replacement card, if that is possible.
The way I see it, you need either an ATI 8500/9000 if your only desired upgrade is the capacity to run larger displays, or an ATI 9800 is you wish to do gaming, graphics and be able to make full use of all the new Tiger graphics facilities.
Cheers!
Karl
