I have a Panasonic Projection Monitor PT-47WX52C.When I turn on power it blinks 3 times .What do I have to do to repair it? Thanks Kathy


You will need to replace both convergence ICs and also possibly the associated low ohm resistors, since the 3 blinks is indicating that the convergence has failed. The PT47WX52 convergence repair kit is available from www.tvrepairworld.com which has the two ICs , heat sink paste, low ohm resistors and the CD with repair instructions.

Blinking power light


Hi,
Power light blink 3 times shows that convergence out ICs got defective and need to be replaced.
If you are handy with electronics stuff repair and can solder parts in circuit board with proper tools then replace two big black ICs, convergence out, mounted on aluminum heat sink.
Or call local tech to fix it.
Let me know if you have additional question.
Thanks.

I have a jvc/av-65wp74 unit. The screen went blank and made a pop,pop,popping sound. we could not shut it off with the power button, which was blinking off and on. We had to unplug from the wall. we waited...


Try unplugging the Convergence amp board, which is located behind the speaker grille. If the set will power up with the Convergence amps unplugged the ICs will need replacement. I have seen many JVC in both the WP30 and WP74 pop through the speakers when the ICs short. Unplugging them takes them out of the equation and the set will power up but the pic will have severe convergence issues.

CONVERCENCE PROBLEMS


did you replace the convergence resistors with the ICs? Often the resistors will need to be replaced also when new ICs are installed. 3 blinks means convergence Failure so its either the solder connections on the ICs or the resistors need replacement. If you need more assistance please let me know.

Tv repair


My Tv was doing the same thing, and I had to unplug the set in order to get rid of the blinking light. And what i did was to turn the power on and as soon as i saw the picture i turned it off, I did this 5 times and on the 6th time I let it power and tv stayed on, however something did happend to my set, i found that my convergence was wacky. Tried to center convergence but i could not center the blue. Turns out, i think the problem is with my Convergence ICs that went bad. I can still watch tv but the Image has blue color shadows and the picture slightly bows inwards from top and bottom. To sum this up, i will need to replace 2 ICs, IC C5AA00000203, and this should fix my problem. I will do this repair myself, each part is about $41..

Let me know what happened to your problem.
Thanks
Tony
