Hi im new to this forum, and looking help.
The TV started to go wrong while already on, the picture got thin white horizontal lines, and a chirping noise coming from back of the tv (the tv program was visable just with the white lines across it). I tried turning the tv on and off with no change, so i unpluged the tv and left it for 3 hours +, once turned back on the only picture displayed were thick vertical yellow lines (no actual picture just the yellow lines filling the screen), + the chirping was still there. I took it to the local repair shop but he was unable to repair it saying he thinks its the main board. Once back home i turned on the tv and there is now NO picture at all although the back light is coming on and the sound is working fine, there is no chriping noise coming from the rear now.
I've changed the main board and the LED driver/inverter board, but no change.
Any help or advice would be most appreciated.
ps sorry for the long post just wanted to give as much info as poss.
