    We have had are tv for 13 months and it worked fine until now. When you go to turn on the tv with the cable remote to turn everything on, the tv will not turn on now and if thats not enough the volume wont work either by remote control. Please help. We have tried new batteries, a new remote, the original remote to the tv and nothing has helped so far. Please Help.

    I have the same problem here. The 50" plasma Toshiba just keep trying to turn on it self (for like every 3 to 5 second, it turns on and for every 3 - 5 it turns off, and I did not touch anything). I hope there is a solution before I ship the thing to service.

    MY 50' TOSHIBE WONT TURN ON. POWER LIGHT JUST KEEPS FLASHIN RED

    it wont turn on

    I have the same problem on my Toshiba 42PH95. It is 3 years old. I bought the schematics, which are very weak, since they leave out the Power Supply. It appears to the center of the issue, made by Senseng (spelling?) part no PSC10131F. Discount-Merchant.com had this part but 0 stock now. I am an electronic technician, but not on TVs so I followed the power on circuit. 5volts is present at the power switch and switches when the button is depressed. It goes via a few connecters to a logic board and switches there into a chip (gate array) many ins and many outs. But no outs respond.
    My actual problem is a little different in that I grt no flashing Red Led on the front, just some relay clicks when power is plugged in and no response when the power on/off switch is depressed or same with the remote on/off, nothing.
    AC fuse is good, power gets to the power board. 5 volts and 3.3 volts are present. I disconnected the Sein board per a few posts, but no help.
    I hope this might help someone, and I will let you all know if I get a resolution.

No picture, sound works. Screen flickering

It sounds like the video output isn't
working its most likely a component
failure 1 thing you could try is connecting
a rca cables from video/audio out on the set to
another set vid/audio inputs to see if it the video gets
through.This is a problem that requires technical
knowledge and test equipment to trace the video

Hello
Your TV is in warranty period I thinks. If so, company is liable and will repair it free fo charge. There is "repair,replace, refund gurantees. Your gurantee card and broshure will tell you that. Look at it.

Have a toshiba 50" Plasma TV purchased 11/06.

I do not think there is an issue with the TV. I do not think that the station themselves broadcast the Closed Captioning.

Power turns off right away

Its correct, Sony is no more selling plasma and I think many companies has already shut plasma production and CRT TV as well.
All TV manufacturers are busy in LCD TVs.
