I have this Insignia that I picked up, not sure of its history or anything. When you power it on, it turns on, back light comes on but the screen is white. If you press the menu button or even otherwise, there appear vertical lines that seems to shift left or right sporadically. I opened it up, the boards all look good. Also measured the voltage on the Tcon board, it reads 11.9V and several small regulators on the main board read voltages like 3.3, 2.5, 1.8 etc. Any one have any guesses as to what is the problem here?
