Re: LG 50PA6500 no picture, random pixels.
One resistor is for VSCN and the other one is for -VY, the board shows which one is positive and negative by using + and - signs.
This DM does not look very advanced but is enough for this job.
Now you remove the buffers from the TV and just run Y-SUS on it's own, measure -VY and VSCAN, are they stable and matching the panel closely(+ - 5V)?
