White lines across screen and color faded.

Those lines are called vertical retrace lines. They appear when the G2 (screen) voltage is set too high, or when the video amplifier fails or lacks the high voltage supply (200v).

Have you got any electronics experience? You will need a multimeter and soldering skills.

If you do or know someone who does, take the set apart, look at the video amplifier IC (it is on the board at the back of the tube), get its model and download the datasheet. Find the pin that is labeled "high voltage supply" and with the set turned on measure it against the one that says "ground". You should have somewhere between 180-210v there. If that voltage reads zero or a very low value, the amplifier circuit is shorted or the power supply is not working properly. Unsolder the video amplifier and measure again, if the voltage comes up then buy a new amplifier IC, if it doesn't it's time to check the power supply. I believe you can find a service manual easily, follow the directions there.

Safety precautions: Do not under any circumstances touch the leads of any capacitors, and stay away from the big fat wire going to the top of the tube. Do not do anything inside the TV while it is plugged in (except measurements), and always use well-insulated tools. The high voltage section of the TV does not pose any health danger, however the shock it can give you will make you jump back, possibly into something sharp.
