Looks OK. But what about the manual? I assume you tried everything from the outside of the TV before opening it up and I'm sure you're seeing what you're seeing on the waveforms, but the manual shows:
"External equipment has been incorrectly connected.
Incorrect input selection."
"Correct all connections.
Press correct RGB1, RGB 2, VIDEO 1 or VIDEO 2 button."
Also,
"The monitor turns off in 5 seconds after powering on and then the STANDBY/POWER indicator blinks in one second intervals. It indicates that the power
supply circuit or, one or more fans have been damaged."
So before we tell you what to do next, tell us what you did first. If there's VCC, obviously there must be some sort of life in the PSU, is there any of this power light blinking?
