So I came across this LG 42PX5D.
When I got it, it went into protect mode and I found the Y SUS board was bad, so I replaced that.
Unit no longer goes into protect, front LED goes green and stays there, everything looks great... but no picture, nothing. All voltages from PSU check out, I can hear both Z and Y boards buzz, all fuses good, no change if Y or Z is disconnected... So I replace the control board. Still nothing. All LED's on control board light but the 1st one (D15?) All the red LED's on the digital board on the left light, with the exception of LED204 - which comes on initially but after it cycles, stays off. All LED's on the right signal board lit.
Still no sound or display. Display has no activity at all.
What could I be missing?
