Question about Samsung LN-T4665F 46 in. LCD Television
Try a hard restart, which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. This technique reprograms the electronics, to a certain extent. If the picture does not return, then you have a more serious problem, that requires the attention of a TV repairman.

Turned out to be a faulty screen driver board. If you take the back off of your TV you will find several power supply, sound boards and TV driver boards in the middle of your TV. Down each side you have a screen matrix driver board that has something line 24 drivers down each side of the TV. Just one of these channels had packed up.
I was lucky enough to cone across exactly the same TV as mine with a damaged screen on ebay, I purchased this and swapped a board from this into my TV and it burst into life.
You can type the part number into google ane these boards are available but they cost around £150.00p but I bought a whole TV with a U/S screen for £60.00p so I was lucky.
Hope this helps,

I have noticed and think it may be temperature orientated. Switched power off to allow the TV to reset and once TV and room was warmed slightly - it works OK.
