Mitsubishi VS-50800 50 in. rear projection TV won't stay off. Power button on TV and remote will turn it off but it comes back on after a few seconds, to a setup screen. Pressing "Menu" on the remote will walk back to main menu screeen but one more time turns it off, then it comes on again by itself. "Home" button creates same result. None of the other remote buttons nor the ones on the TV except for the Power button have any effect. While on the setup screen I can use the arrow keys and center button to change options. Any ideas?

Hello, try holding the power button for 5 seconds and see if it will come on, otherwise try a universal remote programmed to a mitsubishi tv. If it still won't come on it might have a problem in the power supply....tks

just re-read the trouble-shooting section of your owners manual and check the setup on your remote

did you try new batteries in the remote? if the tv has buttons on the side and one of them being power di you try to push that? did you push tv power or cable power holding the buttons longer? those things might work.

This is called the blinking green light of death-----only one of two things can cause this problem.

First: remove front speaker grill (IT PULLS OFF) AND remove inspection plate behind it; look for the two bundles of wires coming down and to the right from the front keyboard of the set.

Unplug both plugs you find (different and marked so you cannot mix them up-----the idea is to take the front keyboard out of circuit-----set will still function with remote as receiver is behind front screen)

Try (after 70 seconds) to turn on with remote

If it comes on---defective reset button on front keyboard----use set only with remote or remove and remove actual reset switch---it is located behind and part of frame for screen----entire front screen would have to be removed to get at it.

Second: if disconnection of the front keyboard does not help, the DM unit is bad.

As you look from back of set it is large metal box at extreme left side.

The blinking light is the unit trying to "Boot" up-----these have a problem where caps and a few other parts in that unit fail-----kits on the net are available----Mitsubishi no longer sells or services these units but PTS Electronics does repair them.


Let me know if you have questions and try disconnection of the front keyboard FIRST.


REGARDS, SD TECH

When it shuts off and the green power light goes off, press both the menu and input buttons on the front of the set (not the remote) and hold both for about five seconds and release.

Power light will blink a two digit error code like 2 blinks and then 3 blinks and repeat it several times.

What is the error code?

IF model number posted is correct and green power light comes on for a few seconds and then goes off:
On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.

Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code is found and I will tell you what it means.

Mitsubishi VS-50111 Tv does not stay on.Turn Tv on and shuts off after a few seconds.

Could be h.v. splitter.pull the lead coming from the flyback that enters into the h.v.splittter. Put lead in a quart jar and turn the set on and see if you hear a hissing sound, if you don't see a blue arch also. If set stays on then h.v.splitter is bad.

What a great tv this is Mitsubishi did a fine job making this one, but......only an authorized mitsubishi servicer should repair it. This set records diagnostic led codes that the technician receives to help determine where the problem might be, not the problem, but in which circuit it might be. The one thing to try is, unplug the tv , let it set for a minute, plug it back in , turn it on and hope it reset the micro. Next , call for mits. service.

try removing batteries from all remotes, a faulty remote may be turning your TV on/off. If it still does this, there is a power problem and you likely need a tech to look at it.
