LG 42PJ550, Power supply Board EAY60912401

[keithf2]

I have this Plasma TV, am getting the 5v, going to the main board and voltage coming back, but no other voltage. 1, does anyone have a circuit diagram for this board. 2, found Q802 shorted, anyone know what type of component this is, ie part number.

Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem

All I asked was if anyone had a circuit.

Generally there are no schematics for LG power boards published. If you need further help you WILL have to post a picture of the boards and parts of interest.

Have swapped the power board and now have the screen lit up but large BANDS running from top to bottom. Will post picture later.

Am trying to load some picture of what I am getting on the screen. This fault occurred when I tried to monitor the Va and VS monitor points which are close together which I ended up shorting. and this is the picture I now have.
