    When turning on the TV the green light lights up as if the TV is coming on and then it clicks back off within a few seconds. This is with the remote as well as manual.

    WT-42313 turns on (green light on) with either remote or tv panel button THEN immediately shuts off a few seconds later. It won't stay on.



    Wondering since the previous two posts are within months of my problem occurring if we're not all experiencing a defective part or problem that's just being noticed now? ie: happens after 'x many hours of use?' And wouldn't you know it would happen just when the Olympics are having swimming finals tonight!

It could be coolant leaked from the CRTs, or a failed fuse due to the conv ICs shorting out or going open, depriving the turnon circuitry of its proper voltages.

These are the usuals. Since Mit has very elaborate protection circuits, it could be anything. More troubleshooting needs to happen before we'll know more.

I do a phone coaching service if you want to check that out.

I have a mitsubishi wt-42315. when i turn it on it shuts down right away. any thoughts?


Do the self check this model has.

When you turn it on and green power light goes out:

on front of set press and hold both the menu and input (or device) buttons at the same time for at least 5 seconds and release both buttons.

The 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 and I will tell you what problem is.

If this helped rate this solution as very helpful as I do this here for free.

After a few minutes the color goes to intense red and green


My tv didn't turn green, but the red separated significantly. It started off happening after a few minutes of being on (I suppose the defective part was "warming up"), then it got to where it was like that immediately upon turning the tv on. In my case, I had to pay a tv repair man $350 for a new part. There are 2 microcircuits that control the color alignment--one that controls the red only, and the other controlls the other 2 colors, blue and green I believe. Maybe your part is the blue/green controller, mine was red. The repair man said these parts fail so rarely they don't stock the part. The cost of repair may be different for a different part, but either way you have to choose if it's worth that cost to you. If you get rid of it, I'll buy your tv stand ;-), I bought mine from a friend and didn't get the stand in the deal.

If your TV is less than a year old, I would suggest to call the manufacturers and ask them for an authorized repair center near you to fix it under warranty.
