WS-55809?.

Usually this means in this set one of the two pico fuses that protect the convergence circuit is blown.

This model uses two of the STK-392-570 CONVERGENCE IC'S.

What you need to do first if you are able is remove the back cover and locate the fuses---I can tell you where they are on the board. Check both of them just like you would check any fuse. If either or both are blown----you have found your problem. The set will detect if either or both are bad that no voltage is reaching the Convergence circuit and it will shut off.


I can tell you the least expensive place to get the parts and I have step by step start to finish instructions for this repair if you are handy and know how to solder etc.

Considering the total parts cost would be under 25 dollars--if you can do this repair you can save a lot of money--most shops get 300-400 for this kind of repair----I know as I have done hundreds of these repairs----did a Mitsubishi a few days ago with the same two chips bad---about one hour for me in the customer's home.

I have START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS SET.

I have photos of the fuses and location also--if you decide you want the instructions and photos we will find a way to get them to you. I am not permitted to give MY email address here--if you know what I mean.

If you have ANY QUESTIONS OR WANT the instructions etc---let me know--I am here to help and I do know a lot about this type of set.

First thing is for you to find out if either of the fuses is gone----if they are----you MUST change both chips and or fuses etc.

Our Mitsubishi projection tv went out one day. When we went to turn it back on all it does is blink the green light for a few seconds and then shuts off. What could it be? Where can we look to see where...


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"(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 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.

Tv want power on light blinks 2 times and stops and then blinks 2 again and so on


Hello,

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where,if otherwise the power supply board is dead, do you know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hoping this will here in solving the problem.....

Panasonic TCP58S1 has no pic. or sound. Red light blinks 9 times.


It's dead. 9 Blinks means the display adaptor is dead. If it's still under warranty, you're covered.

Kv24fs120 dead set with two led blinks


Two-blinks of the "Diagnostic STANDBY/TIMER LED" indicates one of two things:

1) Horizontal Output (Q502) in shorted on the A-board.

or

2) IC702 is shorted (CB board)

Two-blinks of the diagnostic red LED is a " B+ Overcurrent" problem.
The red LED will blink 2-times, stay off for 3 seconds, then blink 2-times. The cycle repeats.

The circuit board is quite delicate. One should not attempt repairs (unless one has high quality vacuum desoldering equipment such as a PACE desoldering unit).
