No picture only sound

You have to start by verifying the power supply outputs, the scan drive outputs, and the CRT emission.

I would think you have to bring the set in to a service shop to have it properly checked.

White lines in tv whats the problem??????????????

Check the cable that you are using. If it's a "single" shielded cable, it maybe letting in "air" frequencies, like you have an antenea hooked to your TV. Especially if you live in a city that has several Tv stations near you. The cable could be to old and has breaks in it, or not grounded properly.

Jvc 32" has grouping of thin white lines at top of picture extending 4" down from top of frame

It sounds like you have a bad capacitor in the vertical circuit. The circuit needs to be checked out by a technician. Stargazer

JVC AV-32F704 32" TV Picture is blurry - cannot read any writing on the screen

You didn't mention if you saw fine white diagonal lines running through the screen from top to bottom. If so, you likely have a shorted Picture Tube which is not usually fixable. If there are no lines seen running through the screen, then it is possible the High voltage transformer which also has a screen voltage and focus control built in that could be bad. I would expect the cost of that part to be about $100, so the repair cost total could approach that of a new set I would guess.

Top of the screen Picture Problem

sound like you have 1 or a couple of leaky/bad capacitors in the tv's vertical circuit, typically, there sould be 5 to 10 caps. in all, but you just need 1 bad one to cause your problem. good luck.
