MItsubishi WT 46809- not staying on when turned on

My Mitsubishi WT 46809 is doing the same as described before. The TV clicks on, no image appears and the "timer" light turns green and it then shuts off in about 10 seconds.

    Is it possible to buy the appropriate fuse and replace it without a lot of technical knowledge?

  • sohonet Apr 03, 2008

    unplugged for about 3 weeks. Plugged in, worked fine for hour and shut itself off. turn on, stays on for 5 seconds and shuts itself off. Unplugged for 2-3 hrs, re-plugged in. stayed on for 15-20 seconds, raster came up, and shut itself off. turn on again, stays on for 5 seconds and shuts itself off. unplugged for 48 hrs, it stayed on for 30 minutes with no problem. I'm expecting a charging overload thing. Not likely a thermal, that I can see.

My Mitsubishi TV Model WT-46809 has the picture turn greenish pink after the TV has been on for a little while. What is the possible cause?


These sets did have one common issue where red, green, or blue would do what you are describing.

The set has 3 picture tubes and each has a small circuit board plugged to the bottom of it (bottom of the tubes faces down) and a ground would break loose or a part do the same.

I would examine the picture (see if you can take one and post it somewhere for me to see---picture will tell me a lot).

The ones with the ground broken usually show it more on the sides then in the middle of the screen.

Let me know all you can.

I am a top expert on this site.

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
