Unfortunately, I'm unsure on how to assist on this. I'd have to refer you to the Samsung customer service center in your region.
I have just switched on my 32 inch samsung tv model # LE32a456c2d and there is vertical multicoloured lines running down the left hand side of the tv. A couple of hours ago I was cleaning the TV and some water may have got in but I didn't use a lot of water on the tv so i'm not to sure if that caused the problem. Please could Somebody help me?
