You need a new main board. You can order one on ebay but make sure its the correct model/serial TV number on the back label of your TV.

Your TV main board is damaged and you need a new one. You can order one on ebay and fix it yourself. Make sure you have the TV model/serial number on the back label of the TV to have the right part when ordering.

Your TV is in Protection Mode right now. A part inside the TV has failed and the TV will not turn ON to prevent other parts from being damaged. The red light blinking is an error code for diagnosing the problem part on the one of the power supply boards. The problem boards that need to be looked at is the Backlight Inverter Board or the Main Power Supply Board.
There is a slim chance you can leave the TV unplugged for an hour so the TV can discharge and reset itself. But other than that, I would use the warranty if possible. The TV repair shop maybe expensive, so get some price quotes to see if it worth the trouble.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

It sounds that there is some loose contacts to some connections to your Plasma display. Almost all plasma displays will have similar configurations to display circuits, will change only with the size of the screen. If you wish to get some details http://electronicshelponline.blogspot.com/ Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product by anyone else could result in serious injury or death. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact the nearest service centre.
