This all problem may exist in your tv
1. High voltage problem/ deflection circuit problem.
2. Shorted picture tubes.
3. Problem in the vertical deflection circuit.
4. Problem in the audio ouput circuit.
5. Problem in the convergence circuit.
6. Problem in the power supply regulation.
7. Problem in the portect circuit.
8. The common high voltage arcing that Toshiba sets do at the picture tube.
so for getting pictures gently tap on the side of tv if it works then there may be some loose connection you can fix it by soldering

This could be several diffferent circuits on the tv that is already busted that could cause this so I'm suggesting you to beirng this to anear repair center and have it repair there for your safety also , But if you have any experience in electronics you can try opening the TV and check for some busted IC inside it.

Hope that helps.......

The red light indicates that there is a power problem - a fuse has possibly blown.

there are several fuses in this tv. but they do not look like normal fuses. also when they blow it is for a reason. the most common reason is the convergence circuit. when this circuit goes bad it blows one or two of these fuses. you will need to get service for this television.

Mitsubishi ws55813 picture turning off


The model indicated has a self check feature.

If turned on and green power light comes on and a few seconds later goes out:

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

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

Let me know what error code you find.

If you unplugged the set--you will have to plug it back and attempt to turn it on--unplugging set clears the error buffer.

Power surge from storm. Power light turns on for 2-3 seconds and goes off. Previously had a power supply replaced 3 yrs ago. tv is approx 12-15 yrs old.


MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR 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 protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE 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 twoblinks--this is the most common and easiest to fix.

before you rate this information or if you have questions let me know what you find.

Sounds like your lamp has failed. May not be physically blown but the 5 blink code indicates either the lamp or ballast has failed. Normally its the lamp. Good Luck!

Picture & sound go on & off every sec, red light blinks 5 times


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.

Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...
