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.

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.
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!
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.
I have a toshiba 50hm67 tv and with mine the blue light would come on and I would hear sound first and then the picture would finally come on... this happend for about a month.... next the yellow and blue light would come on but the pic still wouldn't come on until it clicked off and on by itself for about 10 min this went on for about a week. All of a sudden last night the red lights by the power light started blinking. No tv now and when the tv shut off it said lamp not working.
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.
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.
