Hi everyone. I've been given a dead Pana 55DX600u that I hope to save from landfill. I suspect the tcon board or UC1 on that board.
Set will flash green led and attempt to start, backlight gives a brief flash then set shuts down and red led flashes slowly. Voltages out of PSU look ok. TCon board gets 12v at fuse when attempting to start and 3.3v on L1 but main IC gets warm very quickly (heatsink/cover removed, felt with back of hand) during the second or two the 12v is applied before PSU shuts down. TVS diodes on lvds input lines are not shorted, no caps appear to be shorted.
If I attempt to start TV with TCON lvds disconnected the led will stay green.
Is UC1 on TCON board likely dead? Any further assistance would be hugely appreciated.
