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...
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...
I have a 2011 13 inch MacBook Pro here.
The MacBook runs super slow and fan runs on high. No knowledge of previous liquid damage, no sign of corrosion anywhere on the board.

Ran ASD EFI and am getting ERROR - SMC IO failed.

This MacBook was originally water damaged. I cleaned it and replaced the left I/O board. With the bad left I/O board, the backlight would flash at startup and then turn off and stay off. Replacing the left I/O board solved the backlight issue.

I have a board that suffered a liquid spill 9 months ago. Board did not have any heavy corrosion, was surprisingly clean.
When I connect a MagSafe, it lights up green but the board does not power on.
It powered on one time after the cleaning...and stayed on. Booted to a folder with the ...
This MacBook was liquid damaged. After cleaning, no components were replaced as everything other than a few keys on the keyboard was working good.
I ordered a replacement topcase, and after installation, the power button doesn't work and the fan is running at full speed.
I've tested the board...
I have two 820-3115 boards that have RAM slot issues. The bottom slots are bad so the MacBook works with one stick of RAM in the upper slot. When RAM is in the lower slot, it beeps and does not post.
What are my options? I'm not sure if this is repairable or if it's just a waste of time...
So let's all agree that the fume extractor prices are outrages. $600 bucks for a box with fans and filters plus another $120 for some hakko color coordinated hose?
I'm convinced we can build better fume extractor for a fraction of the cost.

I wasn't getting voltage at the fuse, replaced U9701 and got voltage. Now it appears the circuit is not being boosted to drive the backlight.
I also replaced 0910
I'm getting 14.3V on PPVOUT_SW_LCDBKLT on the LVDS connector but no backlight.
I'm guessing there...
Having a no backlight issue on a 820-3476 board after liquid spill. No corrosion was present on the board as it was a really recent liquid spill. Cleaned the liquid spill residue, have chime and video signal but no backlight.
The fuse is good.

When I test...
I got a few syringes of the amtech nc-599-v2 flux from Louis and it works great!
What the best way to dispense it? I've seen syringes that come with needles on Amazon but my question is whats the best thing to get to dispense the amtech flux..
820-2936 was originally liquid damaged. There was corrosion around the LVDS connector. I cleaned the board and swapped the LVDS connector. Backlight works but it seems that not all the LEDs are working. I'm getting a spotty LED backlight pattern (see photos). It's not the display because I tried...
