Problem w/ Mitsubishi WS-65869After losing power

Problem w/ Mitsubishi WS-65869: After losing power due to a momentary power glitch, the tv will not power back on. All I get is a flashing timer light. Tried unplugging then replugging. Tried pressing the reset button. Nothing works. Same thing happened several weeks ago and somehow I got the tv to power back on after about 1 week. Now I've had another power glitch. Not sure what to do with it.

I found this answer and I believe it fits your problem perfectly.
Your TV has two microprocessors that depend on each other for communication. The problem is that a power glitch gets them out of sync. Try this:
1. Press the power button and wait for the blinking light to stop.
.
2. Press all the front panel buttons one at a time, except for the reset, and power button.
This will send a command to one processor and sets an interrupt.

3. Hit the power button, and the TV should power up.

4. Set the TV to low energy mode(see TV manual to find out how to do this. Doing this step will help prevent the problem from coming back. These instructions were taken from a Mitsubishi service manual.

Yes, you need to replace the convergence output amplifier IC's. They can be ordered on line. After removing the back you must remove the circuit board which houses the amps. Then desolder them and install the replacemnts. If you are extremely lucky there won't be any re-alignment issues with the new amps. Then you should be good to go.
