Hitachi 42EDT41 42 in. HDTV-Ready Plasma


The Tech you had come out could be dead-on from what you've described... It could also be a bad connector. I've attached a couple of photos here to my explanation. One is a picture of what I am guessing you see on your screen when you power it up. If correct, you could possibly take a look at a line connector between the joint and formatter power board yourself and see if any of this is damaged. To answer question more pointedly, (1) There are more than three boards inside, actually nine major board modules to be exact. (2) The Y SUS board, Hitachi p/n#TS05679, without going into great detail, determines the image position on the screen. (3) Cost - - Tritronics has this board at a list price of $436.22 and they are not as easy as they might appear to a layman to change...

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.

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.

Missing voltage?


alot of voltage adjustments at that high voltage are likely from another source that develops it like the the swith-mode power supply upstream on power supply board that feeds it ..look for burnt resistors in this case.. I bet your in the wrong circuit but u can test all wires and pins coming in for 200 volts. get a schamatic of it and find a good tech if u dont know what i am saying. ty crazylarry
