Problem with Samsung LN-T4665F 46 in. LCD Television
No picture
When I turn the TV on the picture and sound come on for a split second, then the sound stays on but the picture goes black. I can't pull up the menu or anything. It's like the tv just shuts down the picture but still plays the audio. Any ideas?

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 had the same problem. It turned out that my cable box needed to be rebooted. Now everything is fine. Try unplugging your cable box, wait 30 seconds, then plug it back in, let it boot up and then try the tv again.
my 46 in Samsung tv did this to me too! took me a long time to get it fixed (and $250 ) ,but i had my backup tv i got from here http://geo.tv-in-pc.com/?source=04017w5r86o3en6qzirpkewq3m
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.
