Hi all can you help I have this set I bought it cheap as gets half a screen only
I replaced the top buffer board as It never heated the heat sinks at all on upper buffer
Bottom buffer heats up no problem
I've tested the y main all mosfets diodes check out
Could a test mode bring full screen on
I have checked the y board over and noticed 3 resistors that are located near where top buffer is someone has worked on them before as soldering is lumpy
Any ideas please
Y main part number EBR63450401
Upper buffer EBR71853501
Edit
Auto ex gen test mode works on lower screen only
