Does these heatsinks look suspect to you ?

[rob@mitrax.com.au]

Hi Guys,

I'v got a LG 50pz570 which powers on no sound no picture.

Looking at Y Sus the heatsinks appear to be badly discoloured . Is this normal or is it an indicator of issues ?

Title should read "Do these heatsinks look suspect to you ?"

it could be convection causing the heat to all go to that end.

What is the fault/symptom you are having with your TV for you to suspect the heat sinks on the Y-SUS Bd?

Please research on how to test Plasma Ysus boards, no point throwing a board in if you have not tested it. Give us the Vsc voltage and Vy which is generated on there. Also Lg generally have shit designed Pcbs so wouldn’t surprise me if alot of heat in that area has discoloured the heatsink.
