R6114 was missing. U1900 showed signs of someone else's work and looked untrustworthy so i replaced it along with y1905. I couldn't find the exact clock chip on any donors but plenty with the same prefix which I assumed to be acceptable substitute? termination traces beep. Looking through the...

Thanks for the insight guys

Hey guys, looking for a hint or two on how or whether or not to even proceed with this one. Thanks in advance! No LD visible upon receipt. D7012 was knocked off. replaced and restored pp3v42_g3h green/orange light. Began checking rails and of course everything is present up to PP5V_S4_RS3...

Sold a mid 2012 13" on eBay (yeah I know). The bottom cover was cosmetically pristine however it was not the original piece. The buyer ran the serial number on the cover which apparently returns as being 2011 and opened a return under "not as described" stating that it is not in fact a 2012...

Someone should correct me if I'm wrong but there were several years that had high failure rates to the point a class action lawsuit forced apples hand. For whatever reason those gpu's were all shit and since no one can buy direct from manufacturer the likelihood of a refurbished chip from those...

Gotcha. Thank you!

Swapped out ram and reset PRAM again - now i get image on external and nothing on int, not even bklt, I can't confirm this display as known working though. Would it ruin christmas if a mid 2011 13" air display were plugged in? Current status: I attempted to fire up asd but it hangs on "loading...

Greetings! Hoping you guys can help me get my head around this one... LD'd *restored to s0 state *chimes on *have backlight *screen is initially a warmer "greyish blue" that visibly begins transitioning brighter until finally white *responds to pram reset j9000 pins burned (replaced)...

1v14. I read a post where a member reflowed an smc, no change before he removed and reballed the same smc with success? Do you ever recommend this or waste of time? (Given ppbus_g3h isn't 12.2 indicating bad smc) I'll try reflow. Any other ideas?

Yes sir. Nothing on speaker. I'm looking over the audio circuit now to make sure it's capable of beeping. XW6701 was missing but looks like that's for mic. odds that the audio and usb circuit are trolling? garbage under smc?

No LD visible but dark red TP's all over... So something happened. Restored cpu vcore and ddr rails. All power rails present now Pm_pch_sys_pwrok is present. powers on, continuous fan spin, no usb mouse light. Dead cpu?

Sorry, i'm not sure if Im following you here or not. My balls did end up hershey kissing in areas which I tried to flow out but the most of the balls have a "cracked" texture. Are you saying use fux on it after they drop off the stencil?

I decided to try failing at some bga rework and managed to meet my goal many times since yesterday. sorry about the terrible photos. What do make of this and am I anywhere near a ballpark of any sort?

Ahhh. Got ya.

No intent to hijack here.. Just some curiosity: Changing lcd cable requires prying off the bezel or top glass piece correct? How are you doing this without scratching the display itself. I puled a good LCD out of its housing without damaging it in order to throw it into a display with...

You are correct sir! first smc reball... Fucks sake that was a learning curve. Anyway... Thanks for the reply.
