Hi,Thank you for using Just Answer my name is ***** ***** I will help with your question. Could you let me know the model number of your TV? Would you be looking at repairing the tv yourself?
I am sorry but I feel that secure remote assistance will not help with your question as it is used more for computer related issues
Thank you for the model number. The tv is a LED TV and I suspect the problem you have is caused by either a faulty LED Driver board or a faulty led strip which is built into the screen. In my experience it is more common for it to be cause by a faulty LED strip than a faulty driver board.The screen may be repairable but it is a fiddly job to do. I can talk you through the repair if you wanted to tackle it yourself.
