is it completely dark or just very dim or dark on one side? if it's just dark on one side, you have a failing LCD panel, very common for older Samsung panels. If it is completely black on one side split down the middle, you could be dealing with a bad panel, bad t-con board, or a faulty LCD panel ribbon connection.

sounds like a bad smps or bad display. I would try the smps, but if that doesn't do it the display costs as much as the tv most likely.

It sound the the panel is faulty. If you wish to get more details, check this site. Pull up older posts there. Check the site with patience, as it has over 2250 posts now.

This is a common Power Supply / Backlight Inverter Board issue. If you open up your TV you will see a long white board that is on the right side of your TV. You have to replace that board to get this issue fixed. You can find the board here BN44 00264B Samsung Power Supply Backlight Inverter

no sky channels only free view channels

The tv power supply board is not the problems,that can add a transformer to solved it easily.The problems are US and Europe uses a difference tv signal frequencies.The US,Canada and Mexico are using a NTSC signal frequencies.Europe,Asia,Middle East and Africa are using PAL signal frequencies.U must have a tv that call REGIONS free tv to work in Europe and US same time.If u just have a standard LCD or a Plasma HD tv buy it in the US for example will not work in Europe

TV display inverted colors, like a negative photograph because defective panel. Mostly from T-con board. Replace T-con board.
I hope that will solve your problem.

The tv have 2 long boards call the LCD inverter boards.These 2 long LCD inverter boards are dead.These 2 long LCD inverter boards help the LCD screen panel to have a backlight to produced a picture.Tries websites like Shopjimmy.com,Ebay.com to buy these refurbihes 2 long LCD inverter boards for the replacement.

I have the exact think happening on my Samsung LN46A530 and it has just been 2 years since I bought it. There better be a cheap fix for this because a $2,000 product has to last a lot longer than 2 years.
