hi
I bought this TV 19 month ago. when i connected it to PC with HDMI cable and watch the TV suddenly horizontal black and narrow lines appeared in whole screen. from left to middle of TV and disappears in right side. I disconect Pc but problem exist in all situation such as video input, digital tv, sat and etc. a tv repairman said that this is a epidemic problem in this model and because of lg panel that used in this tv . he said that can fix this problem for 600$ with repairing panel. is it true?I think he was lying. is this problem because of capacitors? how can i resolve this problem myself ? i have tools in home and Experience in electronics. please help me and give a tutorial manual for fix this problem in home.
