I have a 27in. I'art JVC TUBE TV about 5-10yrs. old & at the top of the screen I have about 6 or 7 small white lines. What could it be. Help if you can.thanks.farmerbill. .

The tube is going out on it

Its a frame fault if the lines are only on the top of the picture ..it sounds like a capacitor fault near the frame chip .but this could be down to dry joints .i think the first thing i'd check is the frame chip.check the legs are soldered properly.hope this helps ..farr64

Fougzki is correct. The solution by Parkj doesn't know what he's talking about.

Check capacitor pertaining to vertical IC maybe drying up or dried up already. Its an old unit this capacitor especially eletrolytic may dry up.

Hope this helps.
