Hi,
I have a LG 42LK450-UB with stationary horizontal lines across the screen. They are mostly green and purple with a large tan band across part of the screen. photo one. sorry forgot to rotate them. Also getting a whine/buzz on t-con board. I think its coming from the components marked 220 y2 in photo 2. The tv immediately goes to the lines. I get no menu or logo or any sort of source video. The back lights are on and if I remove one of the panel to T-con cables that side turns white. Voltages off the power supply are good, and the A-dim and p-dim are 3.1 with tv on. I'm thinking main board because of the no sound/no picture, but would like to verify that before buying a new one.
Thanks
