Question about LG 42PC3DC 42 in. Plasma HDTV
Lg 42pc3d plasmano pic sound but no pic i took it apart and there is a blowin fuse i was told it is the hv board were is th hv board located and if so were can i buy a new one.....thanks
My experience is that the Z-sus board has blown! . this because a little power supply on the Y-sus board is defective. This power supply feeds the drivers for the Z-susboard. replacing the Z-susboard will result in a working tv but it will allso blow sooner or later if the little powersupply on ths Y-sus board isn't repaired first! this little pwer supply, supplies the +15 volts for the gate drivers of the Z-susboard and if you measure on those gate-drivers you'll see that the supply voltage has dropped considerably due to bad elco's on the little power supply on the Y-sus board.
Replace those bad elco's first before installing a new z-susboard!

I think you probably mean the Y-Sustain board which does have fuse which can blow. This board is on the left hand side (as you look from the rear of the TV). Occassionally other factors can be responsible for this fuse to blow such as the buffer PCB which works in conjunction with the Sustain board. An established repair service centre or a supplier on-line will porvide a replacement for you.
