iMac A1174 20" 2.0ghz 2gb memory Apple iMac “Core Duo” 2.0 20-Inch Specs Identifiers: Early 2006 - MA200LL - iMac4,1 - A1174 - 2105 I have done a search through the ifixit links and repair post and the help section but am still a little unsure if this is a dsplay problem or an inverter problem. The screen is a solid mass of stripes ranging from yellow to blue,(full spectrum) all about apixel wide. Previous queries have been about a band of stripes, this is the complete orchestra. What I need to know if it’s the disply or something else like the inverter, I don’t have a mini dvi hook up so can’t check the screen on another onitor and don’t have one anyway. Appreciate the help. Your site has kept my Powerbook alive for the past 14 yearrs or so. Keep up the great work.
Thanks I have a pic but can’t see where to upload it.
You can use a simple video converter, plug it into the small video slot on your imac or MacBook & connect to an external monitor( you may need to toggle on/off ?f3 f4…) however the outcome will probably be your video card, for such an expensive machine _ can’t they afford to use good quality solder ? You have to tear the whole thing apart & re-solder it all. with such small pins you pretty much need to either hold a high gun on the board back & forth for a few minutes (after removing any melt-able items from the area you want to “re-fuse” back together, sometimes hairline imperfections. Some say bake it in the oven for 6-8 minutes. Other than looking sleek & modern, I’d prefer the tower version, fix or replace video card - back in business.
The upload for images is a tab in the lower left hand corner of the screen. This sounds like an LCD issue to me rather than an inverter problem. Without tthat monitor test we can’t tell if it’s the GPU. Without being able to test it that’s not much you can do on your own. Here’s a couple of things to try, but they probably won’t help. Reseat your RAM one stick at a time. Reset the SMC and zap the PRAM. I’d take it in to the local repair place. Sorry.
The Mac in question is indeed not a G5 but the very first Intel iMac, check here. In my experience it’s screen and GPU failing TOGETHER! Even if you replace the screen (the G5 screens won’t work on this machine anyway) the problems will persist or kick in shortly after. As much as i like to fix things - i’d discard the machine or use it as a server.
Hi everybody, for anyone not getting a free repair, don’t throw away your imac yet! If you’re willing to give ubuntu (a linux distribution) a try you can still make use of your computer with a little trick here and here are some notes about installing ubuntu on an imac:
