Tv automatically powers off by itself within seconds.


This model has a self check: with the set plugged in turn it on--green power light comes on and a few seconds later goes off.

On front of set press and hold BOTH the menu and input buttons at the same time for at least 5 seconds and release both buttons.

Power light will blink a 2 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 it means.

I do not use this TV that often, I only turned on once a month or so. Yesterday, I tried to turn it on, by pressing the power on button, nothing shows and within 3 sec it turned off by itself, regardless...


when set comes on and then goes off: on the front of the set press and hold both the menu and input buttons at the same time for longer than 5 seconds.

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

This is the self check feature this set has.

Tv powers down every time we try to start it. We turn it on and it immediately turns itself off.


Please do the self check it has: when it shuts off and power light goes off, on the front of the set press and hold both MENU AND INPUT for at least 5 seconds and release both buttons.

Power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat the error code four more times.

If this information helped you rate this solution as very helpful and I will if you post a comment here tell you what it means.

I do this here for free.

Turns on for a couple seconds and immediately turns itself off.

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

Tv shuts off immediately


check first for the contact point of your control panel button maybe the tact switch is shoted specially when your always using remote control for function operation.second check power supply for leak capacitor or change in value,check also the photo coupler for leak test or change in actual.

TV turns on but turns itself off after short amounts of time


This set is equipped with LED diagnostics. Once it shuts down on the front of the set hold down the MENU and INPUT, (sometimes labeled DEVICE) buttons until the LED starts blinking a 2 blink sequence. For example one blink pause two blinks long pause and then repeats is the code for no problem. All of the fault codes begin with two blinks and then one through 4 blinks. I suspect that yours will be a 2 - 4 code because of loss of vertical sweep. Which is bad solder connections on the deflection yokes. A common problem with these units.

Mitsubishi WS 65513 turns itself off


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

PT-47WX49E Doesn't work


This is for sure a safety shutdown circuit that is shutting down this TV set. It is a hard call to pinpoint a problem such as this without first doing some troubleshooting on the TV set. You could have a short in the sweep power supply, the horizontal output transistor could be bad, therefore then the flyback is probably bad, or the vertical IC could be bad, there could be a regulator problem in the main power supply that could be bad, and also the convergence IC's can cause this problem. Almost any circuit inside this TV set can be detected and staop the set from starting up. Good Luck
