TCP42ST30 6 Blinks

[Plurxtc1]

I have a TCP42S30 that uses a TNPA5349 with 6 Blinks. I check the SC2 Connector with both probes and it displays 120K ohms. If the board was short then it would show .03 Ohms. I checked the Mosfets to see if they were short and they were not. Any tips where to start?

Found a short on Q441 DG302. I will give an update once it's been replaced.

Buy a screw update from Shopjimmy. They have lock washers to prevent another failure.
