Three possible causes:
Power supply module with poor DC filter caps, Bad T-CON board, Backlight inverter board. Those are the assemblies to check.

No pictures can be due to no 24vdc for the backlight, bad T-CON board (have backlghts but no pictures).
Please try below first:
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Gray faded look on top to picture


It can be the plastic anti polarizing screen that covers the display.

Often it causes grey or red shadows on top of the picture.

TV picture fades, then shuts off


There are some components in the scan amplifiers, and or the power supply area that have become unstable. This can happen with age and use. It is impossible to make an accurate assessment without actually troubleshooting the set.

You need an experienced TV service tech that is strong on troubleshooting, has the service manuals, and has the proper set-up to work on your set. I would recommend the factory service rather than an independent service tech unless you know for sure that the independent service tech can handle this type of repair.

Considering the age of the model of set that you have, I would be looking at replacing it rather than fixing it. Because of the age of the set the reliability will be decreased.

The only thing I can think of that would make the picture fade to black is a loose solder joint on the filament supply. Each of the 3 picture tubes has a filament and if the 6.3 volt supply to those filaments is suddenly lost, the picture fades to black as the filaments cool down. An experienced tech can find and correct this for you quite easily.
