Are those (on) voltages when the set has gone into dark mode?
Have you got a known source dvd playing or pc input?
When it is dark can you see a very dark image on screen - perhaps with a flashlight
on the screen at an angle.
We are going to need pictures please post one of the back of the set and one of each board - must be clear in focus. Use manage attachments jpg less than 3mb

when it says please wait how long is that displayed.
maybe it is searching for a source which is why I asked for one to be connected.
Did your friend say what might have happened - went off while on? didnt come on? Power surge? lightning?

It stays on for 2 seconds. I connected a DVD player and no change. He said turned it on, no picture but had sound.

Does it still have sound?

On the inverter board test the secondary windings on each of the small transformers

No power to boards meter on ohms 2000

no sound, OL on transformers.

I get no voltage at CN8802 (connector from power board) on the inverter board. What should it be?

Well that is jolly lucky for you - You see where is says DANGER high voltage
- It really means it.

You are either on the wrong pins on the small transformers or need a higher scale on the meter - is there a part number on the transformers
use it to look up the pinout.

part # 80GL32T-14-DN
DARFON 6518A 921115Z

I could not find any info on the transformers. I tried every pin combo only reading besides OL was 000.6 ohm on middle and 4 pin using a fluke 87.
