Hi, I just wanted to recap. I wanted to find the exact reason why I wasn’t getting all my signals for lvds. I’m not sure this is correct but on pin 458 of u1800 I have a dead 0.00v short I removed (R2465, R2460, C2465,C2466,C7781,u7800) on this line and on u7800 Pin 1 (PP1V05_S0_PCH_VCCADPLL)
I still have a dead short. I’m guessing it’s directly from PCH. So I’ll go ahead and replace thank you 2informatico and piernov
