Question about JVC AV-27720 27" TV

1 Answer

Sound is fine, picture not

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

This sounds like a loose solder joint, or overheated component. I know this may sound like a **** question, but have you tried tapping the TV to see if it goes away? If it does, you will need a tech to re solder the loose component. I have also seen this type of line and color bleed problem, believe it or not from poor cabling or loose connections.

Black comes across right side of screen


Sounds like you've got whats called a cold solder connection somewhere in the horizontal width control circuit or a connection in the sweep section. Should'nt be two expensive but unless you have had some soldering and troubleshooting experience I would leave this on to the pros. Good Luck
