Most likely your problem is caused by a fault on the Vertical Stablization board on the Red CRT. Remove the speaker grill, then remove the screws that hold the mounting board that contain the speakers. Look inside the TV to the left. You should see the Red CRT. On the side of the yoke towards the bottom of the Red CRT, you should see a gray or dark plastic housing. You should see wires with a with white plug on the end, that plugs into a board on the side of the Red CRT. That's the Vertical Stablizer board. Take a piece of wood and lightly move the wires over to one side while turning the power button on. Your TV will most likely power up.

This is the #1 cause of most of the Flashing Green Light Of Death Problems you see with so many of the Mitsubishi Rear Projection TV's made since about 2000. The reason for it is because Mitsubishi runs the power feed into that board, then daisy chains it over to the Center CRT, which then feeds to the CRT on the right. It's causing the Red CRT's Vertical Stablization board to be overloaded on the power feed circuit, thereby causing the contact on the little PC board to burn. If you are good at soldering, you can mostly likely get behind the connector where the plug goes, and resolder the terminals, making sure you first unplug the tv, and let is sit for at least a half hour before working on it. Wouldn't want you to get electrocuted and have a bad case of the frizzies.

Good Luck and hose this helps.

Mitsubishi big screen HD 1080 series model WS-55809. it switched off one day. and when i turn it back on it switches right back off. red light in front. what part do i need to fix it/


That model does not have a red light---Green.

If set powers up for a few seconds (green power light) and goes out do the self check the model indicated has:

On front of set (not with remote) press and hold both the input and menu buttons for at least 5 seconds and release both.

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

Let me know what error code you find (if you have unplugged the set that will clear all errors and you have to plug it in and try to turn set on again---when it fails do the self check)

Turns off immediately after turned on


Do the self check it should have: when shuts down and green light goes out: On the front of the set press and hold both input and menu buttons at the same time for at least 5 seconds and then release both.

Power light on set should blink a two digit error code: like 2 blink,2 blink, pause and repeat it at least 5 times total.


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

Mitsubishi model WS-55313 worked before we moved to another house, now it turns on for 2 seconds and then shuts offwhat can I do?


DO self check this model has.

When power light goes off, on the front of the set push and hold BOTH the menu and input buttons for 5 seconds or longer and release both.

Power light will blink a error code--like 2 blinks, a pause and 2 blinks and will repeat it 5 times.

Let me know the error code and I will tell you what kind of trouble you have.

I have a mitsubishi big screen tv model 55809 , as soon as i click on the television 2 seconds later it clicks off.


The model you have selected should have a self check feature: when turns off and the green power light goes off:

ON THE FRONT OF THE SET PRESS AND HOLD BOTH MENU AND INPUT together for at least 5 seconds and then release both buttons.

The power light should blink a two digit error code: for example: 2 blinks, a pause and 2 blinks--it will repeat the code about 10 times.

error codes for this set:

1, then 2 no error detected
2, then 1 X-ray protection
2, then 2 short protection
2, then 3 deflection circuit problem
2, then 4 vertical deflection problem


2, then 2 is the most common and easiest to fix.

Let me know what you find and if 2,2 I have detailed instructions for repairing that kind of trouble.

I am here to help people.
