Mine too. I pushed and held the power button in at which point the red light turned off. I then pushed the power button and the tv came on and is working fine. I hope this helps you. Good luck.

There are videos on YouTube on how to fix the black line problem on plasma TVs. There is specifically a nine year old boy named Nico that shows how the repair is done. It is a simple problem but time consuming because you have to take the back of the TV off and maybe two other large parts. The problem is caused by solder that separates or breaks and you just take a small tipped solder iron and reflow the solder. It might take someone that doesn't know much about TVs, a couple hours but it is fixable. There is an AV forum online that shows pictures and instructions on exactly how it done:

While the posts on this forum are old-most of the plasma TVs are basically the same as far as how to fix the problem. We're getting ready to takes ours apart because it has a black vertical line on the far left of the screen. Our problem started about a year-and-a-half ago but we've just been too busy to fix it but I'm tired of it so we'll try it.

If you have a box or something, try going into the menu for that instead of the TV's menu.

Mother board replacement to Plasma Displays is a very skilled work. After replacement, there are so many adjustments should be done. A software update might be necessary. Are you equipped with all the testing equipment and have skill to do this work. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center. If you wish to get more details about this repair work, check this link.

that set should blink a error code with the red light. Let me know how many times the red light blinks and I will assist with the issue.

In that case the problem of your television is the power supply.The power supply have low voltage output so that the board of your TV cannot drive,so that the TV wont turn on.The power supply have leak capacitor that may cause of abnormal voltage.The output voltage of the power supply is +5V, +12V, and +24V.So the power supply is the problem its need to repair.Thanks

It's called Cyan and it's sound like you are having a problem on your D-board. Look for capacitors bulging out and replace first if not then order D-board

Check the fuse at the main power regulator board. If found open, replace the main power board as card basis. Normally there is no repair to these boards. Card must be replaced. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.
