Problem with yours is it may be down to the voltage regulators

What is part number on U21

EDIT Found this:

So I reckon that means the 50117B-G should produce 1.8vdc

You mean the IC ? It's a AS15-F , here is the datasheet https://cdn.badcaps-static.com/pdfs/...7296e32c12.pdf
I'll try to found more Info of the Regulators meanwhile.

I cant see them either - perhaps the 902 IS a 1117 so 3.3 would be correct
903 is still a mystery.
VGMA - See top right of the tcon pictures there are 22 test points with
capacitors underneath som have the labels above otherlabels are to the left.
Just start at one end and list the voltage on each one

Also datasheet for 50117

I added an edit about one of the regulators.

AS15-F is known to be a problem chip - could you replace one if you had to or is it
going to be a new board?

Depends on the price, i can get a used t-con from China for 37usd (less then 25euro), i'll check the price of the As15, just for curiosity.

Ok i ordered 5x AS15-F from China for 5USD, i'll wait them to arrive and i'll let you know, thank you very much for the help !
P.S : I contact the local tv technician and confirmed me that the AS15-F is highly defective

Hello again mate selldoor and the rest that helped.

Thank you very very very much selldoor
