    I have a Toshiba TP50H15. The problem started with the convergence changing, then it would pop back. It progressed to a flashing power light, but I could reset by unplugging and replugging. This worked fine until we went to Arizona for 3 months. Upon returning, it wouldn't power up, but would flash the power light. I did get the menu to come up a few times before the light flashed, so I know that function is there. I suspected a voltage problem due to dust etc, so I brushed and vacuumed everything, then replugged connectors. Now, the channel will appear, but the background screen is red, so I may cave contributed to the probnlem. A service manual would sure be a help. I have seen comments that this is probably a convergence IC. Also saw a link for replacements for about 9 bucks. Do you concur that this may be the problem? If so, which one is for the red? Thanks. I like this set and the Home Theater sound and sure would hate to junk it if repairable.

    "Found replacements att Electronics Parts Center oonly $8.94 each."

    BTW, I found a Sony Service Bulletin that listed STK392-110 (old number) and STK392-150 as the new number. Does this apply to the Toshiba replacement as well? Both appear to be available, but the new number is a bit cheaper. Are they interchangable? Did they just increase the voltage rating?

No picture and the power light blinks

A red blinking light could mean that the lamp timer is at it's limit and it is time to change the lamp. You will also have to reset the lamp timer by pushing and holding down 2-3 buttons on the tv or remote. Refer to your user guide for the proper way to reset and or change your lamp.

Power problems problem on

I would try a power drain:  Unplug the TV's power cable so the TV is not grounded to the house.  Then press and hold in the TV's own power button for one minute to drain the capacitors. Plug the TV back in and see what happens.  If the TV will still not turn on, I would say you have a problem with the TV's mainboard as a dead power supply will not light any LED's for you.

it could have over heated you can try to reset it first unplug it for about five minutes and try to turn it on if that dont work the remote might have a set button try holding that down until the red light flashes twice, then turn it on if not then hold the power button down on the set for a good five seconds to see if that resets it. if none of that works you will have to go to panasonic .com for the reset instructions.with the red light blinking the power supply is most likely good you just need to reset i.
