At f7700- 8.6v r1300-3- 3.42 so weird and feel like it's just at the tip of my fingers.

Dead at L7520, u1950 has voltage at pin 8, looks like u7501 enable pin is not being "enabled". U1900 has voltage and looks fine around it. The burnt probe point is 1123 on the lcdbklt_en_div_l net. Think that would have a weird tie to it some how?

3v3_s5 is present. At L7560. Resistors around SPI are Ok. Only thing that was visibly corroded after replacing the lcdbklt area, was one probe point opposite the lcdbklt_en area. It's completely burnt and gone. Could this be the cause? Also, scope is effed up.

hey everyone, have an 820-00164 that gave a brief display, and fan, then no fan and a sim green/orange light. Isl6259 was messed up, so I changed it out, seems to have fixed the dim mag safe light. Also changed burned components around lcdbklt_en. Have pp5v_s5 but no pp5v_ s4rs3 or S0. Any ideas?

I suppose that suggests vcore, but there is voltage and everything looks fine around the buck converter.

No, a wired mouse does not light up... damn and I remember larossmann doing a video on this. Can't remember what a non working/USB suggests.

dukefawks, U8300 change again, intermittent display/backlights. It seems like after a while u8300 is getting blown, but presently, I get a flicker on the LCD, but the weird part is I'm getting display and bcklt voltage even though it is showing nothing (no glow and no display). When I turn it...

@dukefawks: solved, I had a different q7155 in it, changed it out, problem solved. Thanks!

Also no chime

@dukefawks Smc_lid measures 3.3v out of the computer. R5071 measures 98ohms

@larossmann U9000 p1=0 Ppvcore_S0_cpu=.87 R7402=Looks fine and measures 91k ohms

820-3208 with corrosion only at u5010, r5000 and c5025. Changed them out, cleaned the area, turned on and display worked. Ran ASD with no issue. Suddenly the display stopped working. No more corrosion around the board, no BKLT voltage, no display... ideas?

Fixed a botched screen repair for a local shop. He didn't disconnect the iPhone 6s battery and smoked the backlight filter. Changed it out, back light works, but have bars for display now. Known good screen. Sorry for bad pic. Any idea? My schematic simply says "42" for that BKLT filter... I...

Problem is, board works 100% fine, runs on MagSafe or battery just fine, but it's not recognizing charging. I plug it in, boot it up, it shows a charging lightning bolt but when I click on the battery it says "battery not charging". Probed around isl6259, all resistors seem to be within spec...

Yep! Always!

dukefawks, I tried a different battery, seems to not be overloading mag safe anymore. Problem is, board works 100% fine, runs on MagSafe or battery just fine, but it's not recognizing charging. I plug it in, boot it up, it shows a charging lightning bolt but when I click on the battery it says...

Have a coffee damaged 2936. Got green light, fan spin after replacing components. Still boots, then pauses and shuts down. Components near the edge, r4510, u5410, c5411 and the ISNS_HS_OTHER_N circuit, seemed to have most of the corrosion. Further, the resistors smc_kbc_mde, smc_tdo, smc_tck and...

@glenn Sure as shit. Had to take out ram from my wife's computer to test. Apparently all my spare RAM is bad. I did not think this to be possible. Thanks!

No but when I mess with them (change position, take one out etc.) it changes how fast it boots and resets. Will try.

3115, no liquid damage, boots just over half way, then resets about 3 times in a row, then tries resetting again. Any clue? SMC?
