Without having the unit in my shop I would have to say it is one of two things. The power supply or the inverter. You will have to find replacement parts online which will be about 50 to 75 bucks.

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional

2. Open your TV and find PSB. Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

I have a tip/tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shuts off on its own problem.

Hope this helps and Good luck.

The red flashing light is the service code. My guess is the power supply is bad now, but it could be something else. If the TV is under warranty, take it in and get if fixed. If it is not, then you may try to check the power supply first. Count the flashes of the red light and check online for the issues when this model flashes, 4 times or 6 times... or 9 times, etc.

Good luck!

that bar is a menace to clear. somtimes manufactures put problems in so when you tell them the problem they know what to do this is how they make money

You either have a bad Main board or simply a bad touch control button in other word one of your side buttons is defective and it is blocking any other signal to the main board, but usually its a bad main board. In some cases ther is a FIRMWARE update from Panasonic, you may want to call Panasonic or check there website for any type of FIRMWArE UPDATE.
