Re: 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.

your television is going to need an internal repair. most likely in the power supply of the television. it would be best to unplug the television until it can be repaired. If you would like to repair the television yourself then please use our premium service so an expert can walk you through it. Or you can search for a local repair service using our local repair search engine.

White lines

These are retrace lines. This may be a fault in the blanking circuits. On some occasions a weak CRT can also cause blanking lines to show.

This is something you would not be able to service yourself. I would suggest to have an estimate done on the TV set for you to decide if it should be serviced or not.

The faint white lines at the top of the screen is the warning that the pump-up capacitor in the vertical output circuit is going bad and the output itself is about to short out. When the TV stops working, the vertical output IC has finally shorted out. Replacing the vertical output IC, the pump-up capacitor and possibly a small value resistor next to the flyback (B+ for the v-out) should bring the set back to life.

White horizontal, zig-zagging lines

It sounds to me like you're describing the re-trace of the unit. It is repairable, and more so the sooner you get it to the repair facility.
