My friend, that's like cutting hair over the phone. First, you have to trouble shoot to see if the power supply is capable of running, and if it isn't, then you have to go into the main board and check for the 5 volts and the 3.4. If you have those then you must check to see if the power supply is getting the on command from the main board. If all that is operating then we go over to the Y sustain module and disconnect the VS and VA supplies from the power supply and see if your sound is restored. If it is, then there's a 90% probability that the Y sustain module is bad. That's about as close as we can get. I hope this helps. I suggest taking it in for a complete diagnostic check.

I don't know why they won't look at it. The boards in a Dell are mostly LG and Samsung. These are two of the easiest boards to obtain.

I just got a new power supply installed in my Fujitsu 50in. Plasma P50XHA4OUS and cannot get the sound to work, we've tried everything, please HELP!

Assuming the power supply is exact replacement and you did not have this before--check the speakers to make sure not turned off.

If using a cable or sat box make sure sound not way down or off both with the set and the box.

Last but not least if sound is there with a DVD---something somewhere is set to wrong position.

It sounds like you have failing capacitors in the power supply. It would be best to have a technician to look at it or locate a power supply for the TV and replace it.

Hi

Thanks for using FixYa. A plasma TV is a very hard working device. It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. X, Y sustain, buffer boards controls picture, fires the gas, and many others functions. When either of these boards goes bad common problems include negative image, no image, vertical or horizontal stripes on picture, turns on and than turns off, and many more. You’ll need to open the back off the TV and check for any swollen/bulged/leaky capacitors on these boards and replace whichever has gone bad. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off. Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
Rylee

sounds like it could be a cabling issue, try replacing the cabling (if you have another tv, you can borrow the cabling before purchasing new set of cabling)

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,
