Ask Your Own TV Question

No just this tv. I just attached a picture

Yes I mean is it apparent on inputs that you may be using from a cable box or DVD player etc. the dark strip is their no matter what you watch?

Ask Your Own TV Question

I don't see the picture could you try and attach it again?

Ask Your Own TV Question

Okay I see it, that is what is know as a backlight strip that has failed, it is an internal strip of LED's that are not lit causing the darker area at the top, the fix for this is complex as the LCD screen needs to be disassembled and the faulty strip of LED's needs to be replaced. Do you have the model number of the TV?

Ask Your Own TV Question

The picture I posted shows what LED back light strips look like you can see how a row of faulty strips can cause the darkness across the entire screen.

Ask Your Own TV Question

On some models you can get to it using the menu / support option in the TV menu if you don't see it their then it would have to come from the tag on the back of the TV?

I can’t get to it.

Okay unfortunately I can't get you a part number for the light strips without it, if you are not attempting to repair this your self then it would not matter, the unit can be repaired. The average cost of back light strips is around 120.00 bucks, shops charge between 150 and 200 additional dollars for labor in most cases. certain shops will repair backlight systems while others won't attempt is due to the complexity of the repair.
