If this is a crt type its commonly attributed to high voltage section fault. A bad HOT or bad FBT. But check first it minor component for a faulty one.

If thhe ic has a crak that you can see then it is no good replace the ic If looks good then look real close where it is soluder ontothe board for little crakes in the soluder where the pins are. I would resolder the ic anyway becouse some thime you cannot see the crakes but the pins are loose. Now there is some capasistors in that cerit also that go bad.You would ned a capasistor checking machine to check these out of cerit.These capasistors that im talking about are usley black with writeing on the side like 10u 25 v this is not for the ones you have in your set just trying to let you know what im talking about. There is a pos and neg side to this kind of cap and they have to be put in just the way they are took out. Try resoludering the ic first then see what happens if it looks ok, if that does not fix it replace the ic and caps. This ic will be mounted to a heatsink by the way.

How old is this TV?
As Tv's age, the high-voltage suffers and they get darker. You can turn up the screen adjustment on the flyback transformer and buy some time but:
My experiance is to not put money into a TV that is over ten years old. TVs stress out their electronic components worse than almost any other electronic product. After 10 years, there are so many parts that are ready to fail that your are probably wasting your money trying to get any more life out of it.
Another option is to wholesale replace the main board from an outfit like Module Exchange at 972-298-1212
Be careful on buying a new one though. Often times, these new technology ones are much worse. Always Google the model number of the set you intend to buy and add the word 'repair' or 'complaint' to see if it is one of the many models that are customer service nightmares being produced by even the most reputable companies today.
Hope ya fix it!

Please fine tune those B/W channels to obtain color picture. If TV is more then 4 - 5 years old, it needs resoldering in tuning area or might need replacement of IF block.

Hi there!
The Video circuit or chip that runs it may be at fault. Refer to a repair technician if not familiar with TV repairs. Good Luck, JUS004

Hi, you can try firmware update online or by usb if it isn't in the last version yet.
The other solution is replace the main board (motherboard)

You surely meant LED not LCD.

Eliminate any posdible issues with skybox and try using a simple DVD player to a different input port.

I don't know but surely if your tv has an option for analogue inputs there will be a range of sockets for the job - phono and/or scart.
If the sockets are there connecting will be intuitive.

Many modern tv sets are compatible only with boxes, converters, decoders and media players that provide a digital output. Analogue to digital converters are available but I can't comment about how successful they are.

I suggest you revisit the user manual of your tv.
