TV has sound and picture but there are little black lines on the top of the screen like three bold black lines in the mid bottom screen and it looks like the picture doesn’t go all the way across to the left side of the TV screen. What causes this?
Hi, I would suspect the driver board. Since you have a decent picture there, what’s missing is the entire signal being sent out. That signal gets split into lots of ribbon cables at base or top of LCD panel and they then power the strips in the LCD. One thing you could try to verify if ribbons are loose/bad or if video driver board is bad is grab the display at opposite corners, like left top and right bottom and slightly twist the case. If the display changes, gets better/worse, then the ribbons are suspect. If no change, then I would proceed to the driver board. My bet is the board. Rare for those ribbons to come loose. Mike
