Question about Mitsubishi WT-46809 46" Rear Projection Television

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

I own a Mitsubishi Model WT-46809, Serial 11382, 2001 September build, television which was working fine.  Now, however, when I power it on it:  makes it's click sound and the power light comes on, power light stays lit for a few seconds, then the click sound again and turns off.  I am unsure what this could be related to, as it made no indication of it's bulb burning out or anything.  I tried to unplug it from the power strip and into a direct socket to see, but to no avail.  Any ideas?

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

Mitsubishi WT-36809 turns on for 2 seconds and then turns off. The error code is 22. Any ideas?


Verify the model number. Some of these Mits. family have bad picture tubes, and oil spills out onto the signal board. Look inside front panel, RHS tube, look below it onto signal board. If you see an oil puddle, then tv is toast!

Mitsubishi wt-42311 green light flashes and turns


Mits are bad about power supply capacitors failing. It can be fixed fairly cheaply, but requires some skill at disassembly of the tv and unsoldering/soldering.

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
