-no picture caused by the Y-Sus deflection circuit
-you will need 1ea. Y-Sus Main
-1ea. Y-Driver upper
-1ea. Y-Driver lower
It is best to change these as a set
Part numbers are dependant on the tvs Product Code which on the back of the unit.

I have a LG 42pc3d-ud i can get green (power light) but know picture on tv (like power is off and have humming sound comming from back


From your description it sounds like your TV it's actually on you just can't see a picture. That is usually caused by your Zustain boards. The zustain boards are located on the left and teh right side of the TV. You can check the fuses to see if one of them is blown or you can leave it on and see if one of them does not heat up. You would have to replace the board. You can find part at www.interliquidparts.com

The problem is the Y-Sus PCB; You'll have to take the cover off and see the model # on the board (this board is on your left side as u take the cover off)
