Question about Mitsubishi WT-42311 42" Rear Projection Television

1 Answer

Will not stay on

The TV all of a sudden one night just turned itself off .When you turn the power on it comes on for about 3 seconds then it turns itself off. We call Mitsubshi and told us to turn off for 20 min and turn on again but that didn't work. Did the bulb go out? Any suggestions?

    I was having the same issues and had a repair service come to my house. They had to replace the amps and things have worked since then.

Samsung TV model LN32A450C1DXZA, after turning the TV on it will turn itself off shortly after and then turn itself back on shortly thereafter. Then it repeats that several times before staying on.

Hi there,

If the tv is still under warranty, this can be repaired at no charge.

However, if not under warranty, you will need to have the CAPACITORS on the main power supply circuit board tested (or replaced).

The capacitors responsible for the power supply can sometimes fail - open the back panel. If the capacitors on the main power supply board look too fat, or signs of burning near the solder joints, then you've found the problem.

Hope this helps.

My tv, when plugged in just keeps turning itself on and off in intervals of about 3 seconds. It doesn't give time for anything to come up on the screen at all.

Problem is in standby power supply or microprocessor area---not the do it yourself repair and likely not economical to repair due to age and brand of set.

Last night the set just turned off by itself. When I try to power on, the power light comes on for a second and then it shuts itself off again.

I am having this exact problem. The TV turned off by itself and now when I try to turn it on, the power light stays on for a sec and goes of with a click sound.

Any TV experts who can HELP?

TV won't stay on

You will have to call an Authorized Panasonic Servicer. Any modules bought from them requires an authorization. Since your not a service center, it's going to be almost impossible for you to do anything. Play it safe and have it looked at.

TV turns on, then immediately off again

hi nel2874

so, you have a television that turns off immediately after you turn it on.
It sound like your power supply on the unit is out. Because I don't know the value of your unit I cannot comment on replacing the unit. But I would recommend that you use our website to find a Flat Panel TV Repairman near you. You may want to call to get an estimate on replacing the power supply before considering replacing the unit.

Turns off after a few seconds

The unit is going in to shutdown. There is a short in the unit. My guess would be the HOT and or Flyback are bad.
