what i thought indeed.. I tested it with gfxcardstatus and no intermittent shutdowns anymore on the integrated GPU. Thanks for the tip!

Have this 3787 in that i'm a bit out of ideas for. It is doing the random shutdowns, often times losing video (but backlight stays on) and staying on like that for a little while before shutting down. I have replaced all FDMF6808's with 6708N i ordered from digikey (so no sanded down ali-shite)...

Any of you guys know where to get the 60-pin LCD connector found in the newer 5k iMac? it?s the lower one in the attached photo.

Alright, thanks for the advice.. i guess i'm going to not waste time on this then!

Hi there, I don't get these boards a lot. I'm hoping this isn't a dead cpu, but just had to ask if there are any checks I can do before sending this back . So it's a 00045 board that has no liquid or drop damage but suddenly stopped working. When connected to 87W charger I get 20v in @ 0,4/0,5...

haha lol yeah.. I finally have it fixed though. Had to run this fucking jumper for the trackpad connector as well, Jesus.

ok, nevermind, found it: pad under C9719 exploded and shorted to a groundplane in the board. Now for a very fun coating and reconnecting job...

Just wanted to add that the short is there with no screen connected

Maybe I'm having an off day, but this board is pissing me off.. 820-3332 came in from another shop, had no backlight. Found an 8ohm short on PPVOUT_S0_LCDBKLT So, i start taking off all components related, started with caps C9715/16/17/18/19, then took off LVDS since short still there, C9000 as...

Had it run for a couple of hours after reassembly today, and it hasnt done the sudden loud fan-spin anymore.. Passes ASD (besides the one error), runs pretty hot according to HWMonitor, under stress the CPU and GPU go up to about 106C, jesus, but ok, I'm calling this a fix and moving on to the...

Alright thanks a lot both of you, will check tomorrow and report back here!

FFS.. makes sense. so basically the EFI ASD is trolling me by giving this false error..? I?ve never seen the error pop up in other machines though. going to try and see what?s causing this thing to have an occasional high fan spin then. Fck me, I?ve been going over this for so long thinking...

Been a while since i needed help, but here's one that's been bugging me for a couple of days. 820-3332 that had some damage due to probably a knockoff charger, had to replace R6920,R6905,D6905 and basically carpetreplaced a lot of things around U6990. Got it back to life, works perfectly, only...

No problem. I'd stock up on a couple, they're quick repairs and you can charge decent money for them. Haven't had much returns, other than a couple where someone managed to damage my jumperwires for the backlight.

Hi there, there is plenty of posts on here about them that tell you the same: they work perfectly fine to revive these old machines. I still install a couple of them on a weekly basis. You loose external video. Brightness control works with the newer versions of the Tiresias. The boards now have...

I have a Mac with the exact same sensor failures: TG0D, TG0P, TG1D, Th1H, Th2H ALL READ -124. Have checked for corrosion: nothing on the board: looks pristine have also checked the mentioned SMBUS traces but there is nothing wrong there. After disconnecting the iSight cable, the Mac passes...

Ah crap, i didn’t know that!! I thought all 27” cards were interchangeable between 2009-2011? Should I tell client A to install some fan control software, cause I think that he will want to keep it for rendering. I know about the leds, I’ve taken all of the tape off and on all machines only the...

OK, just to explain what happened: Customer+iMac 27mid2010 (A) wants a videocard upgrade (had a 2GB card laying around that i sold him for a lower price so i could keep the old (1GB) one. Job done. Customer +iMac 27late2009 (B) walks in and wants to buy the leftover 1GB card because her...

No sorry, i am going to take that advice to heart, I wasn’t clear about that. Was just asking to check if it might also be related to some other issue than the gpu...
