Question about JVC AV-27720 27" TV
I used to be able to jiggle the cable connection and the picture would tune in, but now it's just a few horizontal lines with a partial picture that flickers in and out in one or two of them; screen is 2/3 blank
is it worth taking to a repair shop?
You have a vertical deflecttion chip that is going bad. Probably a LA7832. There is also a good chance that you have a leaky capacitor and bad zener diode. The capacitor is east to get , the zener diode part # is MTZJ75. These repairs are usually best left to a professional
