TV Doesn't stay on...

I see this quite a bit in this forum. I have the same problem with my Mitsubishi projection TV.
I press the power button and the power light comes on for about 3 seconds without sound or picture, then shuts itself off. I tried pressing the menu and input buttons simultaneously but to no avail. Please advise...

65" mitsubishi rear projection tv won't turn


IF model number posted is correct and green power light comes on for a few seconds and then goes off:
On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.

Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code is found and I will tell you what it means.

Problem w/ Mitsubishi WS-65869After losing power


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.

Flashing green light


This is a very serious problem. The green blinking LED means the TV is reading its software but it can't complete the task. The cause is the premature failure of dozens of capacitors on several circuit boards in the TV. To properly fix this, the chassis needs to sent to Mitsubishi for rebuilding. You'll need to contact a Mitsubishi authorized service center to do this. This is expensive and takes quite a bit of time.

Green blinking light on Mitsubishi WS-55813 HDTV


generally this means a bad digital module.. as a techinican the first thing that we would check are what is know as standby voltages. if they were there we would replace digital module.! question. Does it blink for more than 70 seconds. This unit comes with a lockout feature. to unlock press and hold menu down for 10 seconds on front panel.
