You should start for the Vs & Va voltages itself. The details to these voltages will be marked on the panel label itself. These two voltages should be more specific than other voltages, especially to Plasma displays. More variations; say; + or - 1%, can effect the display drastically. To get more details about this, you have to download the repair manual to this set, and refer its schematic diagram.

SOURCE: p50hdtv10a y-sustain and pcb

I had this problem with a different brand plasma and it turned out to be cracked or missing solder on the power board lead to y sustain. I removed the power board, desoldered the connection, clean it up and then resoldered the connection. Everything works great now.

The fault lies in the energy sustain boards, also called sustain boards. X-sus and Y-sus/Z-sus are the to sustain boards. If your meter has capacitance measurement capability, test the caps to see if any of them are fried. Should read OL or infinite if its bad. Try it and let me know.

Zenith plasma tv wont stay on model:z50pj240


This could be caused by multiple things. The first problem that comes to mind is a bad power supply in my experience. The second problem that comes to mind is possibly a bad t-con or backlight inverter board. Could you tell me, when the TV powers back off can you see a picture in on the screen if you shine a flashlight up to the display?

Zenith Projection Tv Set Model number ZB4685T no Visual


Since this is a CRT based set, there could be a number of problems. What exactly do you mean when you say that the picture fades? Do you loose contrast and the picture gets lighter? or does the picture darken toward black?

Parts are still available, so this can be fixed. If youfeel you want to attempt this yourself, please supply additional info and we'll walk down the diagnosis path.

The power supply section is not working.
Common possibilities are:
- Convergences amps have failed overloading the supply
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.

In short, you need a experianced tech to troubleshoot this.

Plasma Screen not working only sound


It might be one of the power supplies. There are three in this model. One for the sound, one for the video, and one for the computer components. The video power supply is probably shot. They cost about $200 a peice from LG. If there was a "pop" sound when the video stoped, then it might be one of the circuit boards in the back. Yet again, they are three, each costing around $200 from LG.
