A greenish tone to entire display denotes a faulty panel. If you wish to get more details to this, check the site linked here. It has screen-shots to faulty plasma display. You can see it and compare to that of your TVs' and can make sure. Pull up older posts. Good Luck.

turned tv off to put on bigger stand turned of with remote and have tried diffent outlets but will not power on

check the Antenna and antenna connection (wire ,jacks Etc.)if there is no signal for few minutes it used to go standby.

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!

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.

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

Not totally sure what your asking but I think your saying your LED lamps aren't working, if that's the case replace them

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.

These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs.

On the side of the TV there should be a button that says "MENU"

Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.

Check the signal cable, resolution of the source and input mode of the TV.
