Should I remove the LP8550 to check the FW trace?

SMC_LID is 3.45V

2.75V on BKL_ENL (measured on PIN 2 of R9715) Will check SMC_LID right now

Working on a 820-2936-B with no backlight. No known liquid damage. F9700 is good. Have 11.09V on and .597 diode mode measurement PPVOUT_SW_LCDBKLT Have 3.2V on P3V3_LCDVDD_SW_F Have 3.3V on PP3V3_S0_LCD_F Any idea why I don't have backlight? Thanks

I realize it's hard to explain air temp/speed settings but what is the trick here to getting these off without melting them? I've tried heating them from the bottom and they still melt.

The MacBook was liquid damaged. Everything except the trackpad works after cleaning in ultrasonic. Looks like the connector is missing a pin. What are my options? I see keyboard connectors available for purchase but no trackpad connectors. These melt if you try pulling one from a donor board...

I removed U7000 and the short on R5281 is still there. What should I do next? Is removing U9400 the next step?

I'm going to replace R5281 and let you know what happens. Thanks!

Here are the diode mode measurements you requested: pin 2 of R5280 is 0.338 pin 2 of R5281 is a short to ground (0.002) to be exact it's not missing "the screw" and I did try using a known good interposer board between the battery connector and the mlb.

This board was liquid damaged. Board was cleaned in the Crest ultrasonic. Everything on the board works, in fact the battery will charge, and it will run off the battery, but the battery is not being detected. I have tried a different top case with a known good battery and a different...

For the record I ran ASD before several times and it was passing before I heated the SMC. The only reason I heated the SMC is because I read a lot of posts here where that was recommended on this forum. Lesson learned. Next time I'll ask before going for it. Anything else I should try before...

I was having the same exact symptoms before and after. Should I still reball the SMC?

ASD passed.

I replaced that trackpad, Ts0P is now passing, but the fan still runs high.

It was failing Ts0P...I checked the trackpad connection and it was partially unplugged. I reseated the connection, ran the test again and it still failed. Going to replace the trackpad and see if that solves the issue.
