On J8500 pin 6 DP_INT_HPD diode value is 1.5 and i took another board which is 820-00239-a and it's 0.45 on the same pin same network and goes directly to cpu...

Yes red probe on ground as it should be for diode mode reading. I check all resistors also replaced R4830 cause on pin 1 which comes from pin 2 of q4830 it has 1.647 diode mode value and on pin 2 of R4830 it has 0.568. I also replaced q4830 but no change. All leads to a contact under the CPU which probably broke cause of overheating

The issue comes probably from under cpu or bad cpu. The client will use it on external for now. Thanks for the help
