Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electro-medical.blogspot.com/

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Only suggestion is if set was plugged in when you did what you did--unplug it and any box or receiver plugged in and wait a while--plug back and let the equipment try to reboot.

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.

Its magnetic effect on picture tube. Power Off TV for 20-30 minutes then turn it On, hope problem will be resolved. Please also check and remove any speaker or some thing have magnet near by TV.
If color spots are still there, picture tube need to degaussed / demagnetized.

Faded and out of focus picture


Your TV has a burnt CRT base socket. Replace that, it is not a tough job, but make sure that you get the exact same type of base socket.

Faded Picture


I would have to say it does sound like the CRT is reaching its end. The thing that points this out that the picture gradually gets a little bit better as it warms up. It most likely isn't worth the cost to fix it.
