You think I Should try to dig in ?

I found the issue , but it looks like am screwed . R4953 was knocked off, now the pad was completely ripped off , I don't know if I will find something if I dig, I fear not to damage something else , there's no TP anywhere except under U3900. If I don't resolve this , the owner might ask for...

I didn't have the clients details, I used a test drive and I did not test the Touch ID , the machine is not liquid damage. I didn't think it would be a problem.

Good day guys, have got an 820-00923 with a faulty Touch Bar strip , so I replaced it with a new one , and it works great, but the client brought it back that the Touch ID stopped working. I try to reconnect the cable just to be sure . but no changes, the option is not even present in system...

since I have already tested a video cable and another screen , I will now check continuity on D8410 and j8500

Thanks for your response... I replaced a different Lcd assembly, the connector looks great, I also replaced the video cable , but no changes . ?Is there an intermediate short cable between MLB an LCD assembly?? I don?t understand what you mean by this , are you referring to the display flex...

Hello guys have got an 820-01041-07 2018 15 inch with 55V on backlight output but has no backlight . I have tried with a know good screen , and a different screen cable but no changes , please help

The 820-3115 are quite common with faulty RAM slot, I suppose you can start by troubleshooting which of the slot is faulty, usually its the bottom one. A little tap when the machine is on could reveal that as well, as that would make the machine to freeze when you do so. I suggest you start from...

what do you get on pin 4? be sure there are no broken traces too

Okay , let me do that

same in in all , compared to a working board

thank you for the explanation.I compared the diode mode readings to a working board and they match,

have got a quick question, is it possible to have a failure on a line that's already has it preset value ? for example , am comparing diode mode to ground on the power rails of the CD3215 even though these where present , so does that mean their presence does not suggest the lines being okay ...

BUF_SMC_RESET_L is present at 3.3V , and F7000 is about 0.02V am now checking on the diode measurements

hello guys , have got 820-00928 that's stuck on 5V. have got PP3V42 including PP3V3_UPC_XB_LDO, my SMC_RESET_L is high , all the i2c lines are high as well , I don't have a short to ground , the machine was not liquid damage . I have the PP1V8_UPC_XA_LDOD , I would like to know what else do I...

okay , doing that now

yes , C7601. and diode mode on L7630 is 0.375

I have tried a new bios but no changes, the board was a NO POWER C 76601 was a bit corroded, so I replaced it and the machines powers on

Have 820-00165 that would power up, and then go off in less than a minute , then comes back on again and stay on . Does not chime and does nor post. I vet cpu vcore. Please where do I go from here . Thanks in advance
