Tv randomly shuts off


next time it shuts down and power light goes out--do the self check.

On front of set press and hold BOTH MENU AND INPUT BUTTONS FOR AT LEAST FIVE SECONDS AND RELEASE BOTH BUTTONS.

Power light (if an error is detected) will blink a two digit code.

Most common is 2 blinks, pause and 2 blinks---set if there is a error code will repeat it at least 5 times.

If you detect a error code, let me know and I will tell you what it means.

I push power button and my 1080 series 42 in. mitsubishi big screen shuts right back off.


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

Let me know what you find and I will tell you what it means.

TV gets vertical colored lines, then shut off, green blinks conti


Bad Capacitors in the Power Supply could cause this. This Chassis has be famous for bad capacitors through out many boards. If you are not comfortable with working on the unit, and most are not, I would call a professional. The Chassis may need to be sent to Mitsubishi to be refurbished. This is a expensive repair and it would be advisable to call a Mitsubishi Professional to confirm diagnoses. Mitsubishi's Customer Service Number is 1800-332-2119. They also may be willing to help with the cost of repairs.
I hope this helps,

TV turns off and power light blinks unpluged andd still does it.


Likely to be the STK convergence chips causing a protection circuit to switch the TV off. Have you got any onscreen convergence problems (i.e, colour fringes)?

Continuosly blinking green light and tv won't turn on.


Either bad capacitors -vented - on power supply board or bad E2P eprom board on DM board.Probably the capacitors-4-1000Ufd and 2-3300ufd.You should get expert help from reputable tv shop.Not really do it yourself fix either way.

TV auto shut off-power indicator light blinking-won't turn back on


You could have gotten an electrical surge that put your set into a shutdown condition and unplugging the set and letting the Microprocessor reset will fix this problem if it dosent blow out the main power regulator as you still or might I say have a regulator IC problem. IF THIS PROBLEM HAPPENS AGAIN MORE THEN A FEW TIMES WITHIN A SMALL TIME FRAME I WOULD HAVE THE SET LOOKED AT BEFORE THE REGULAOR BLOWS SOMETHING OUT!!!!
