In that case you have a faulty part in it. The tv must be opened and tested. Since you still have sound you should start by testing the Y-sus board - the voltages on exit and the return( Va, Vs and Z-bias). If you have never done this before then call a repairman, you can do a lot of damage if you touch the wrong stuff by accident.

Open the back cover and check the fuse on YSUS Board. If the fuse was gone, replace the YSUS board or ZSUS board.

SOURCE: 50 inch Sanyo Vizon Plasma TV. Has sound but no

This set has LG insides, it will have failed on either the Y-Sustain PCB or the Z-Sustain PCB.

Quite common.

Repair estimates should be $250 - £350 depending on which has failed.

Stick it on eBay, it will fetch good money faulty.

Is there a hope for a Toshiba 50" plasma TV which


Hi, it sounds like the lamp is on its way out. Depending on the size of the television, it may not be cost-effective to try to have it repaired. If it's under warranty, then contact either the manufacturer or the place where you purchased the TV, and find out what your recourse is. If it's out of warranty, however, there is a good chance that fixing it will cost 60% or what it would cost to purchase a new one.

Toshiba 50in plasma


Hello brattbabie1,

Ok you have sound and no picture. This denotes that since this is a plasma TV the circuitry that controls the activation of the screen may have become defective. You will need the schematic to show the voltage levels that need to be present on the cable that connects between the screen and the control circuit and a voltmeter to measure those voltages. I would suggest that you get a qualified TV technician to work on this problem, due to the technical nature of this issue.

I hope this helps,

Thank you,
