1.It sounds as though there is a problem in the power supply section and it is blowing a linking component to the board mention.
2. this is only isolated with a schematic and proper electronic detection such as a Scope and meter.
3. You also may have a circuit that gives voltage to the plate that gives light to the luminous plate that may need service.

The screen on my Hitachi 42EDT41 went blank. I still have sound, but no image. POssible problems/solutions? Thank you!


This is a common plasma tv problem. I changed the Y-sustain board and the Z-sustain board and that fixed my "sound, but no picture" problem. You can find both boards on ebay; the Y-sus board is around $100 and the Z-sus is around $50. Hope this helps.

Most likely your Y Sustain panel has gone bad. I would have a qualified service center evaluate it to be sure.

I have a 42" lg plamsa tv the screen went black and still had sound.. found a blown fuse on the board to the right of the power board, when i replaced the fuse,it will power up and then 5 seconds later i...


The fuse you have replaced would have been on the sustain board, now that it clicks indicates a problem either with the control board or the sustain board. You would need to disconnect the connector from the power board to the Y-sustain board (left of power board) to check if the Vs & Va voltages are present, if so then the power supply will be working ok & the problem will be with the previously mention boards. There is the possibility that the plasma display screen could also be faulty.

I have a Hitachi tv and tonight the screen went blank but the voice remained on. does anyone know how I can fix it????


Usually it is the Y-sus that has the problem. This is one of the boards that sustain the picture on the screen.

For this particular issue, there could also be issues with the y-drives and Z-sus. The way to find out for sure is to take the voltages (Va, Vs, Vcc, etc) on the boards and matching them up with the specified values on the panel.

Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:
