Ok, Thanks!

Does Rossmann Group have access to just the LCD panel for this model? If not, any recommended supplier for just the LCD panel? Thanks!

Another note, the logic board I just received I noticed that C8350 and C8353 are missing?? Looks like they broke off next to J8300 video connector. I wonder if they ran this too long in the ultrasonic cleaner?? These capacitors are the LED1 and LED4 return to U7750. Will these missing caps...

Does anybody know if I can use a A1502 screen for testing purposes on a A1398 macbook pro? I have a 2015 and a 2014 A1502 screen I use for testing A1502 models. Just don't want to short out the board I just got for this 2013/2014 Macbook Pro 15". By the way, the HDMI works now with this...

Well neither one of those suggestions did anything, darn it. I would have to agree with you that the GPU is at fault here. I went ahead and purchased another board that they say works and I'll first install that when I get it Monday. To make sure the screen on this one works. I'm going to...

Thanks, as far as heating the GPU, what heat value degree and how many seconds would you recommend heating the GPU to test? Also would you use flux or just heat? Thanks

Ok, started back into the GPU power sequence on page 66. Did not get very far since the first in the sequence: EG_RAIL1_EN = 0V (3.3v spec) .640v diode and 17.6 K ohms to ground so no short. It looks like to me this 1st voltage comes out of the U9600? I checked all the voltage inputs to the...

Ok, I wanted to make sure my DVOM was accurate, so I borrowed a friends newer DVOM and went through all the rails again to verify. And there were some different readings. So the PPVCORE_GPU is still reading 0v however my diode test is .008v and ohms are 5 ohms instead of .5 ohms. Bad meter and...

Yes, I get a steady 12.6v

Thanks for the fast reply. I measure .5 ohms on that line. FYI I forgot to mention earlier that this is the board w/discreet graphics. I do not have a similar board lying around to compare to. So do you think that reading is bad enough to called it a shorted-bad GPU? Thanks

Hello all, I got this one in and it is very clean inside, no signs of liquid damage. I started testing voltages and I have 0v on the PPVCORE_GPU. Diode tested 0v. Short to ground. Is this normally a shorted bad GPU? Should I throw this in the parts bin? Thanks again.

Right on! Of course. Replaced U4700 and now have power in both directions. For those out there that might run into this, before I did what 2informaticos suggested, I wanted to eliminate any other capacitors causing the issue I was having. I check both E85_CC1 and E85_CC2 for either opens or...

Hello all, This unit came to me with no power showing on the USB-C voltage meter, not even the 5v you normally see on these units. So ended up finding a bad power board DC jack. Replaced it. Now it will start and charge just fine but will only charge with the charger cable in only one...
