No Title The display port and cable was hit with liquid so that is my guess. I received it this way. The screen cable has a the end pin blown off. It also looks like it was butchered by someone. I will swap out the screen with another one I have but I will replace the other items first I would...

Back for more fun! I have a 15" retina pro with no backlight. I am attaching a photo of the area that suffered some liquid damage. The issue is obvious, so my questions are: 1) Louis do you have these lvds connectors for sale? Are the connectors the same from 2012 on? ​2) I will replace the...

Ok, here is an update so far: I have replaced the charger dc in circuit from the top right red box in my previous post. Trace from pin 2 of C7194 was bad (P5V1_SW) so i ran a jumper to pin 1 of L7195. Installed new D7105 and soldered pin 1 and 2 together. Here is my next challenge:Q7010 uses...

So I have a 15" retina, finally something worth fixing. However, has been eaten alive by coke I guess. Well, decimated the thunderbolt circuit and charger circuit. The Diode D7105 has only pin 3 pad left, but 1 and 2 are gone. I want to focus on these two first. I am trying to figure out the...

Ok, thanks again for your patience with us.

Sounds like a parts board to me. Just curious, would that be a similar repair to the smc? Can not seem to get a win on these.

If i am understanding correctly(no guarantees) I measure PP3V42_G3H at 3.2k ohms on pin 5 of U6901

PP3V42_G3H in diode mode with no adapter plugged in is .28v, new magsafe board and have green light. Checked a 2012 13" model 820-2936 it had .32v on PP3V42_G3H Not sure how close they have to be

ADAPTER_SENSE 16.5v F7040 12.57v but it appears to get voltage then drop, then get it again i check diode measurement for RTC_CLK32K_XTALIN it is .810, not sure if that is correct. I am not sure what point exactly was the "RTC Xtal" also not sure what point you mean by " 3V42 bus"

I do not have MCP_PS_PWRGD

Ok, I cleaned some minor corrosion on the KBD connector and I know have 3.4v on power pads, but still can not get green or orange light(brilliant by the way Duke) So, now how would I proceed? It was just a small amount of corrosion by the way.

Has substancial liquid damage. Have PP3V42_G3H, PPBUS_G3H,SMC_BC_ACOK(3.23v) When I check the power on pads i get 2.4v for SMC_ONOFF_L. Not sure what is pulling that low. I do not have an ultrasonic to clean the board. Any thoughts? I have checked the ISL6259 and have 4v on ac in, I have pin 14...

Crap its the 820-2879-B

OK, so i read something in one of the forums and it got me curious about the other logic board like this one had so i plugged in a charger and tested some points. Everything was as it was before, seems like it should work but did not. Then I felt the ISL6259 chip and it was very hot. So I put...

Makes sense, but other than trying to remove a bill connector from another board we are stuck right? I have seen on another thread where you use heavy flux and heat the back side, then I also saw where a guy sliced it off the old board. Any thoughts?

Checked all that, looks good. check resistors by the BIL they are good.

Ok, i have a fully working 2010 13" macbook pro. Had some minor water damage and we replaced keyboard backlight and battery. Now after several weeks of use there are random times when the computer lcd will sleep while the machine is in use. You can click any key and it will come back on. If I...

Unless duke has some thoughts I will probably just move on. I have another 13" 2010 MacBook Pro that is randomly sleeping while you use it. I will probably start a new topic on that one soon.

Of course, I seem to get the good ones! Why can't i get the ones with obvious liquid damage around the ISL chip, replace a couple of components and boom! Back in business. Oh, well.....

All The resistors are fine and chowing the 3.3v. I am not sure how to measure the 32Kz from U2800 There is no evidence of liquid damage on the board
