Turns on, sound, no picture then turns self off. blinking light on

Mitsubishi self check: MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

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

PRESS AND HOLD "device"(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--hope that you find 2 blinks, a pause and two blinks--this is the most common and easiest to fix.

The set MAY have the self check feature.

If the set is plugged in and you turn it on and a few seconds later the power light goes off:

On front of set press and hold both the menu and input (device on some) buttons at same time for at least 5 seconds and release both.

Power light should then blink a two digit error code like 2 blinks, 2 blinks a pause and repeat the error for a total of 5 times.

If you get an error code let me know what it is.

Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

DO THE SELF CHECK YOUR SET HAS:


When you turn it on and power light goes off in a few seconds;

On the front of the set push and hold both the Menu and Input (Device) buttons for at least 5 seconds and release both.

Power light will then blink a two digit code, most common is 2 blinks, a pause and 2 blinks--it will repeat the code at least 5 times.

Let me know what code you find and I will tell you what it means and maybe what is wrong with your tv.

I hope you find 2,2, as that is the most easy to fix.

If this helped you rate this solution as I do this here for free.

If power light does come on and a few seconds later it goes off---do the self check that the WS65909 MITSUBISHI should have:

On the front of the set press and hold both the MENU and INPUT(OR DEVICE) BOTH FOR 5 SECONDS AND THEN RELEASE BOTH BUTTONS.

Power light should blink a two digit code--error code---for example: 2 blinks, a pause and 2 blinks.

Let me know what code you get----it will repeat it several times---and I will tell you what it means.

helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

unplug tv overnight. if that doesnt work the powersupply is probably bad.

after holding down the menu and device the led will blink a two digit error code such as 3 blinks pause then 4 blinks then repeat that sequence a couple of times. Need that blink code to help let you know whats going on. The 34 code means lamp abnormality which translates to the power Pwb capacitors have most likely failed.

Does it blink a certain amount of blinks pause a second or just blink constantly with no pauses? Let me know it will blink a code if its going into protected shutdown. And it will blink constantly for another reason.

Hi, this is a very common failure, you need to replace 2 IC chips on your power supply board, marked on the top of the IC`s is this number: MCZ3001D you can purchase them here if you are very proficient at soldering & un-soldering, and the board has to come out of the tv to do this, you might want to call a tv man for this one, but it will fix your set, happy holidays, BMW Rider
