Most of these sets have a self check feature:
UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device”(device sometimes is called input) 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

Mitsubishi big screen HD 1080 series model WS-55809. it switched off one day. and when i turn it back on it switches right back off. red light in front. what part do i need to fix it/


That model does not have a red light---Green.

If set powers up for a few seconds (green power light) and goes out do the self check the model indicated has:

On front of set (not with remote) press and hold both the input and menu buttons for at least 5 seconds and release both.

Green 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 (if you have unplugged the set that will clear all errors and you have to plug it in and try to turn set on again---when it fails do the self check)

Have you acessed the power indicator error code by pressing in the menu and input buttons on the front of the set both in together and hold in for 5 seconds? The led will blink a series of blinks to indicate a 2 digit code which will repeat several times. Let me know what the blink seqience is.

I have a Mitsubishi HD 1080 55


Your unit has some sort of Thermal problem either with the PSU fault, or a thermal problem elsewhere that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. T

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

How do I reset big screen tv to 1080 on remote


You don't.
It should automatically switch to 1080 when and only when there is a HD signal present. Otherwise it will be in 480 and you will need to use the format button on the remote to change the picture size. If it does not switch to 1080 and you know for sure you have a true HD signal present, there is a problem with the unit.
Hope this helps,
