Re: toshiba 50in plasma
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.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Generally if the power lamp is on but the set is dead its the power board, you could remove the back if your comfortable doing so and check the voltages going from the power board and see if any are missing or incorrect...good luck!
it must be your tv was heated on long usage.
sir, try to go to your nearest expert technician. they have tools to use on fixing your tv's hardware. or see if your tv has a warranty to send it back to the place what youve bought it. hope that helps!
I'm no TV expert, but I can share what little knowledge I have, specially what I went through with my plasma TV. It happen in mine, and I got the Y Board fix. When mine was blinking, there was no power, but it wasn't the power board, so searching for an answer in the internet, I found out that it could be one of the boards (Y board or Z board) In my case was the Y board, so I took it to a professional and he fix it for me. IF possible search for: How to troubleshoot TV Y Board.
This tv have a Tuner signal board it is also dead too,this problems happen sometimes,the power supply board dies,but sometimes the Tuner signal board take power surges from the power supply board itself than kiill the tv Tuner signal board too.Try website like Ebay.com to buy a refurbish tv Tuner signal board for the replacement.Fixed this problems,many times before.Blinking power LED light.First replaced the power supply board,than didn't solved the problems,than the tv Tuner signal board it is also dies too.
A common problem with modern power supplies is dryed out capacitors in the power supply, This pulls down the voltage and shuts down the tv. The can usually be spotted if you know what to look for (they swell up and deform a little). It is not a job for the novice. But capacitors are cheap. Try a local tv shop for estimate pete
Turn off set, unplug power. Remove back cover. On brown circuit board left of center, unplug connector PJ63A. Plug in power, but don't electrocute yourself! If you no longer get the continuously blinking red light, hit the power button. If it comes on, the SEINE module is bad and must be replaced.
Had the same problem myself. Took some doing but I managed to find a service bulletin that I downloaded. The problem is with the siene module and all you need to do is unplug connector JP63A from the main board and your TV will work again.
Take the back off the TV (there are a lot of screws) and look on the left hand side of the main circuit board that is mounted in the center of the TV. You will see a small white connector that is labelled JP63A, simply unplug it. Plug the TV back in and let it reboot. That's it, should be able to watch immediately.
This is an indication that there may be a problem in the power supply, possibly bad capacitors, and or defective active components. I would suggest first checking to see if there are any blown fuses, and or loose connections. Past this point I would advise that you either take the TV to a TV repair shop or have a TV technician troubleshoot the TV in home to determine the problem it is having.
