Cheers, I will do that. Thanks for all your advice :)

It doesn't give problems during normal use other than a few graphical glitches that I managed to make happen by switching between internal and dedicated back and forth a few times. A few minor glitches appeared then on internal but went away on dedicated and I couldn't reproduce the effect...

It runs just fine in macos and doesn't seem to mind stress test of the GPU. I did the same test with the heaven benchmark running while I made the CPU run really hard so the temp went over 100deg and left it doing that for more than 5 mins with no issues. I ran the memory test with ASD EFI in...

Tested with a different display and there was no ghosting. I tried to boot into ASD OS twice and had kernel panic both times so I booted into a test macos HD and ran the heaven benchmark for a while till it got nice and hot. Rebooted and loaded ASD OS successfully, ran it on loop and at some...

Since there was no ghosting on the external display but the ghosting was on the internal display while the same tests were running. Does that indicate a fault with the CPU? I'm a little confused by how I was continually getting kernel panic when loading the ASD OS until I reset the SMC. After...

The ghosting is only on the internal display. I ran the graphics test on loop for the internal graphics and 2 errors were logged but no kernel panic. I did have to reset the smc first as I was getting kernel panic every time ASD OS was loading.

I just turned it off and booted it back up with a macos test hd and ran the heaven gpu benchmark for 20mins without a hitch. This time as I monitored the p-bus voltage I didn't see it move from 12.7V at all. When I quit the benchmark, I noticed a ghost of the istat menus drop down thing that I...

Replaced U8900 and still get the kernel panic. I had to run the ASD OS on loop though, it passes one pass. Seems to behave better for a little while after being worked on with hot air.

An image of the kernel panic and the ghosting. Hopefully, it's clear enough.

Hi, I have one here that would kernel panic when running ASD OS but not every time. ASD EFI passes with no errors. I removed the logic board and the only evidence of liquid I could find was a tiny spot of corrosion near the LCD backlight connector on a test point that was just surface corrosion...

Yeah it charges and recognises the battery just fine. All the ASD tests pass just fine now. Thanks again for your help. Can mark this one as solved.

Actually, when I booted into macos, istat menus reports the ppbus @ 12.56V but it was reading a little high before.

I had a look in the area near the SMC where I already ran a jumper wire and replaced a couple of resistors and found that the trace from pin 1 of Q5030 to R5033 was broken so I ran a jumper wire and now with the battery and charger connected I'm getting 12.3V on PPBUS_G3H. The fans are behaving...

It goes up to 12.56V with the battery disconnected though.

It's a hair under 12V according to the multimeter.

I put the board in a spare chassis I have but the right io board is dodgy so it's left unconnected. Also left the camera disconnected. Booted with a test macos and ran istat menus. It's hell slow and CPU is at 99%, temps are stable but the CPU die is not showing a temperature.

The macbook boots up and runs. ASD EFI passes but ASD OS has 2 thermal errors "unknown result code -- test failed" and the fans are constantly running full speed. This macbook had liquid damage, I replaced a couple of resistors near the SMC R5092 and R2502 and ran a jumper from pin2 of R5092 to...

Replaced U3200, powers on and boots macos :) Thanks very much for your help.

I'll replace U3200.

Here are the readings anyway. Good board (diode mode): PP1V8_UPC_XA_LDOD=0.483V PP3V3_UPC_XA_LDO=0.515V PP1V8_UPC_XA_LDOA=0.525V PP1V1_UPC_XA_LDO_BMC=0.520V PP1V8_UPC_XB_LDOD=0.484V PP3V3_UPC_XB_LDO=0.515V PP1V8_UPC_XB_LDOA=0.525V PP1V1_UPC_XB_LDO_BMC=0.520V Faulty board (diode mode)...
