SOURCE: TV wont stay on

shutting down can be due to a blown fuse usually in the convergence section. the fuses are soldered in, with a voltmeter you can measure the fuses. if one is open then probably your convergence ICs are bad. about $250-$400 to have a field tech come to you and replace them. The other possiblity is a CRT (picture tube) fluid leak. this is more costly to fix, to check for a fluid leak pull the front lower panel and check for fluid on the chassis with a flashlight. I have sucessfully cleaning fluid from the chassis with electrical cleaner spray. after covering the chassis with a piece of plastic the set worked fine. A slow drip leak won't hurt the plastic, big leaks are another story.
hope this helps

I am going to post some photos here for you. If you went into the customer menu and tried to adjust convergence and red and blue would move but green is skewed--you have a convergence problem.

Look at the photos and tell me if any look ANYTHING like your trouble. If you have a convergence problem with this model I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS I CAN GIVE YOU.

Timer light comes on and off tv won't come on

it could be that you hav to reset the lamp timer on your tv, when you change the lamp on your tv you should also reste teh timer other wise the tv will think that you are still with your old lamp, and will turn the tv off when it has reached the designated time limit.

When I turn on my tv it will shut off

Model number is WT-46809?


If set comes on for a moment and then goes off(green power light)

ON THE FRONT OF THE SET PRESS BOTH menu AND input at the same time and hold both buttons in for at least 5 seconds---then release both buttons.

Watch the power light---it should blink a two digit code---ERROR CODE---
The most common is 2 blinks, a pause and 2 blinks-----set will repeat the error code about 10 times.


If you find this error code let me know the blinks and I will tell you what it means and may be able to tell you what is needed to correct it.

This is a very common failure on Projection sets. Its called a convergence problem.

You may have one or more of the following symptoms.
  • Screen looks 3D
    Colors don't line up
    One or more colors can't be adjusted when using the convergence menu.
    Screen is bowed or warped.
    No Audio / No Video

Mitsubishi wt-46809 46in wont power on

You need to adjust the votages going to the crt's. As the flyback transformer starts to go out the voltages to the crts can go up and down causing the tv to shut off. It also causes red, green, or blue arced lines to show up on the screen. It can also cause some color fading in and out or flickering. Adjusting the voltages can fix the problem temporarily but in the long run it's a good idea to replace the flyback. Make sure you read up on how to do this safely.

Mitsubishi wt-46809 not turning on

Your convergence amp ICs have most likely failed and that will shut the TV down. You need to replace both convergence ICs they are both STK392-570 you can get replacement ICs with free instalation instructions at the following link.

Mitsubishi WT-46809 Turns on with Power light then turns off

there are 2 fuses -24v and 24 v normally would go out because
covergence ics failled . That would be a shutting down problem cased by missing those voltages.so you would need to replace those 5A (small green fuses) , you would need some kind of soldering and unsolderin skill) and the ics are stk392 570.two also. open the set from the fron ,taking speaker grill off and then the wood board behing (4-6 screws) you the the board in the center big metal heatsink. you would need to work from the back to repace those puppies.hdtvman
