    Sam problem, I power the TV on, the picture flickers and then it powers itself off. I called the local TV repair and they told me that soem boards need to be replaced and it could be anywhere form $70-$250. Any one else have a solution?

    Will it's Rhonda again. I have been working on my TV now for 1 month. I refuse to give up. I finally got some fuses in last Friday. On Saturday my husband replaced the fuse and soldered the flyback like you said, finally. It was working great he went to put the Tv back together on Sunday and felt a little tug with the wires, so he stopped. Right after that the TV kicked off and won't kick back on now. He has tried resoldering the flyback but nothing is changing. Did he mess something up with the fly back or is there something else I should be looking for... Again I want you to know you have been so much help it's the TV that is not cooperating :-)

Once you remove the back cover from your TV, on the bottom left board there is a gray capacitor next to a vertical heat sink and it says KP 2000vdc this gets loose for lack of soldering after a while , remove the board turn it around and clean the area, apply flux and soldering put back on and your problem is fixed, let me know if this worked for you.

The rca itc22 chasis. microprocessor has detected a safty condition that requires a shutdown of the set for safety. THere is about 25 different resons that cause this to happen. The one thing you can deduced form this condition is that one the main fuse is working and that the processor is receiving power. THe most like cause of this condition is a high voltage problem. the horizontal output transistor, the flyback. look for blown capacitors there is a capacitor called cp150 that common problem. Technician have special computer equipment that reads error codes much like that of a car.

WHAT IS WRONG WITH MITSUBISHI TV MODEL WS65819 THAT POPS ON AND OFF?


shutdown is happening= If set has been unplugged plug it back in and turn set on--when green power light goes off in a few seconds:

On front of set (not the remote) press and hold both the Menu and Input (Device) buttons at same time and hold for at least 5 seconds---then release both.

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

Let me know what error code is and I will tell you what it means.

When you turn on power you hear a click and the green light turns on. Three seconds later you hear another click and the green light turns off.


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 bothtogether.


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.

Let me know what you find and I will assist you.

52 Inch RCA TV Model HD52W55 does not turn on green power light blinks 3 times but does not turn on. ive got it to turn on once before, and left it on since, accidently shut it off and cant get it back on,...


The best assumption, at this point, is that the power supply board has died. You can buy a replacement unit from the link below and have it professionally installed.
