PowerPC :: Imac G4 Flat Panel Was Unplugged - Now Won't Turn On?
Nov 30, 2008
I am dog/housesitting for my inlaws. Yesterday, before I left my house I shut down my iMac as always and for the heck of it, unplugged the computer, modem, and router stopped home today, and decided to hop on the computer real quick. plugged everything back in and the computer will NOT turn on. No noise, no lights, nothing. It was fine yesterday--I shut it down, unplugged it, and plugged it back in today---now it is completely dead! So I tried other plugs and no dice. Never had any power or shutdown/starup issue before. I called Mac---but outside of driving an hour to the Apple store--it wasn't much help. The guy did say it was most likely the cord. I would be wiling to try that--as it would be a cheap option, but it looks like I may have to drive to the Apple store anyway to get a cord that fits. I also tried resetting the PMU that Apples site recommends--and nothing. Any suggestion would be great. With the holidays the thought of dropping big $$$ on computer repairs is not appealing.

i've been searching for a way to use an iMac G4's LCD Monitor as an external monitor for any other computer. So far i haven't found a solution for it, so during my search i read that it is possible to remove the LCD display from the iMac G4's case and install another LCD display that you know for sure it will work on any other computer. So, my question is, is this possible? if so, what LCD monitor would fit in the case? i know that there's a problem when trying to pass the wires through the arm, but i think i can handle that since i already tried with some random cables, so if you know of an LCD that could fit in the case.

is this a cause for concern on my part? i'm replacing/upgrading the dvd rom and hard disk.. that's why i saw that wire.

I just bought a Dynex 26" flat panel tv and hooked it up to my mac g4 using VGA cord. I selected VGA as the input with the TV's remote, but after the initial Apple icon shows up when I start the Mac, the TV then displays the "No Signal" box. I do not have the TV hooked up to my digital cable box, as I have no connectors for that. I only want to use it for my Mac. Thanks for any help.

The displays on my flat panel iMac G4 (2003) suddenly have gone 'red': sometimes it will return to 'blue' and be ok. Is this a dying flat panel or can I fixit?

I know that's below the required speed but there's Leopard Assist. As can be seen on that page, it says "Uncertain" ONLY for my iMac.
Has anyone done it with this iMac? Does anyone know? I'm running Panther now and, these days, that's no place to be. I want to get Leopard on my Mac before I have to <shudder> switch back!

I have a 700 MHz iMac flat panel with 1 GB SDRAM and running OS 10.4.11. Almost every time I go to do something, I get the spinning ball and have to wait before it performs the action. I even get the ball briefly when I click OK on a dialogue box. I have run the disk utility to repair disk permissions several times, but that doesn't seem to help. What can I do to get the Mac to run faster as it used to do?

How do I connect a newer 2011 27" iMac to a flat panel via a Thunderbolt to HDMI cable? I've already tried this with two different brands of flat panels (RCA and Samsung) and both get no signal. The iMac does recognize the model of flat panel connected to it, the flat panels do not recognize the iMac, nothing but a blue or black screen. Already tried powering down and resetting both the iMac and flatpanels, resetting the memory on the iMac, trying all the HDMI ports on both flatpanels. Nothing works.
Info:
iMac, iOS 5.0.1

The Dell SP2309W 23" Flat Panel Widescreen Monitor with WebCam is only $300, seems to good to be true. Is it a good monitor, in the same league as the HP LP2475w or the Apple 24" LED display?
I can definitely live with the 23" and can't believe it's only $300.

My G5 iMac developed problems after upgrading latest updates to Tiger, iTunes, QuickTime, ect.
I am now unable to access apps like system preferences, iPhoto, Safari and others. Also it will sleep but unable to shut down. I'm hopeful a new install of my OS 10.4 disk will correct things but fearful my photos, music and FireFox bookmarks may be lost.
My beloved G5 has been flawless till now.

My Powerbook G4 only turns on if the battery charger is plugged in, and if I unplug it, the computer shuts off. On the menu bar, it says charging. I know the battery has to be full. This just started happening last night. Also, I just had the hard drive replaced and I've only had it back for a couple weeks.

**Intel Imac 24 in. 2.4GHZ Core 2 Duo (NOT G5...my bad)
I know the "Using imac as external monitor" topic has been adressed in previous posts and it apparently can't be done. But this is slightly different.
I have this Imac G5 24" that is currently out of order. (won't detect hard drives when powered on 90% of the time and when it does i am experiencing ridiculous lag and random shutdowns...not to mention crazy overheating)
I sent it to tech support and after changing the hard drive, power supply etc.. and still not seeing any improvement i just stopped sinking money in repairs and got a new imac.
So now i just have this useless imac laying around and i figured i might as well try and recycle it into a secondary monitor.. I don't mind hacking it open since i have nothing to lose. I was just wondering if it could be done and if so would it be very complicated? I would rather pay a few hundred dollars in wires and IT than buy a cheap external monitor since its already a decent quality monitor and it matches the new imac

All the iMac mounts I find have arms and such. What about a mount that mounts flat against the wall like flat tv's? I can't find any searching...

Is there a way to prevent the PB from going to sleep after the wall charger is unplugged when using the clamshell mode? I'm going to use my PB as a carputer and want it to run for awhile after I turn off the car..I know the PB will go to sleep when it loses power in clamshell mode..

After having inserted a dvd borrowed from the library which my Imac had a really tough time reading, I turned off my Imac as usual. Since then when I turn my mac on the fan starts roaring and i don't get beyond the first white screen with the sort of clocked wheel just going round and round. I don't have a clue to what to do.

I have an iMac i7 27" and I have a nice 32" flatscreen I'd love to use as a secondary monitor to watch videos while I'm doing other stuff on the imac screen.
What the best connector to achieve this with the highest resolution possible?

I discovered my iMac shut down and to start. I feared it had been fried in an electrical storm the day before, though the whole house is surge protected, and a printer on the same plug was unaffected. I tried unplugging briefly, still no luck. I tried hitting the start button ( on the iMac itself, not the keyboard) a few times over a couple of days with no luck, and unplugged it in prepartion to cart off to a repair shop, fearing the worst. A couple of days later, I plugged it in for one last try before taking it to the car and, bingo, it started! Everything was fine, everything in its place.
A couple of weeks later, I once again notice the computer is turned off and will not restart. I uplug and replug - no luck. I unplug, let it sit, and try it again about 24 hours later.
Info:
iMac, Mac OS X (10.6.8)

Had (used) iBook G4 several months now & thoroughly enjoy it, even tho' I live in the sticks where there's no hi-speed/wireless available; I connect to internet & power, which is fine.
This weekend I went to turn off my iBook & it wouldn't turn off. It's now permanently on, with opening info barely visible (like I need to click on F2 to brighten up, except nothing happens).
Currently using my "back up" computer, my iMac Grape, which is pretty much an antique by now.

Using SwitchResX, as suggested in the related H-IPS thread, i found my WHITE 24" C2D, purchased 27 Jun 2007 from an Apple Store, has the coveted LG Philips H-IPS panel rather than S-PVA seen in earlier editions!! Here is the SwitchResX data:

I took my iMac panel off to clean and when I put it back I noticed as you run your finger from the bottom of the panel left to right or right to left, the glass begins to get thicker and eventually overlap just barely the metal in the middle. I can't remember if it was like this or not before, so I am wondering is this bent? And if so what should I do?

After switching from David's Profile (which was meant for a MacBook anyways not an iMac) to Colour LCD on my 20" Aluminium, I could not believe how dark David's Profile is. I have seen some 20" Aluminium iMac colour profiles but like 95% of them are for 96CA panel not 96CB (which I have). Does anybody have good colour calibration profiles for the 9C6B panel?

I recently acquired a 15" TiBook from someone who no longer wanted it. He took good care of it and with the exception of a few slight surface scratches, it looks practically new.
That being said...it won't turn on!!
My question is -- does the battery need to be good for the unit to turn on, even if you've got it plugged into A/C power? The amber light on the plug comes on as if it's charging, and it never goes off. When I hit the little indicator button on the battery, nothing lights up. It would seem quite obviously that the battery is bad, but would that stop the unit from running off of wall power?
If it's just a bad battery I'll gladly buy a new one, just wanted to check before I waste my money!

I don't know what the deal is. I'm trying to install 2 sticks of 2GB into my 7,1 iMac, and the screw just won't turn. I'm using a standard Phillips head, and nothin' doin'. The screw is now starting to strip, so I guess I'm going to have to take this into the friggin' Apple Store just to have them open the thing.
