Lg 60pc1d-aa

[wozzie]

Hope some one can lead me in the right direction .
I was given an Lg 60PC1D-AA Plasma tv i was told it had sound put no picture .
Problem is the Y Sus board , have found Q24 sum45n25 shorted and two resistors that are open R250 and R251 i think they are 1R5 not sure if some one could help me with the resistor numbers it would be great . Have tested all the fuses which are every where and testing all the low ohm resistors . If i have missed any thing it would be much appreciated if you could suggest any thing else that might need to be replaced . Can those resistors be replace with normal resistors ?
Thankyou
Regards John

Hello John,
Any photo's of the back of the set showing the boards. Nice sharp pictures are always helpful.

These have ipm's that routinely short or even fail open. I would be surprised if that wasn't the case here as well.

These are pictures of Ysus board . Hope this helps ,ill try and take a picture of the back of the set with out the board .

The IPM module's are under heatsinks and may have legends alongside. Can you measure the resistance from any of the supply pins given on them ( maybe 5v, 15V, Vs) to ground to see if you have a short circuit.
You could also check the Mosfets and see if there is a short between any of the 3 pins.

Wozzie's Y-SUS Doesnt Have IPM's....
--Its the slightly later, discrete type...
