: see my other post, sound comes from media box, not monitor, no picture is usally main power board at fault, not giving output to power the screen drivers, replace with new or reconditioned main board, sometimes lvds leads can be faulty, if you have spare, try first, but if fusesare ok on zsus, and ysus, then its usally the power output on the main board to the screen drivers at fault, commom problem on these sets

main power board at fault, the power supply that feeds the screen drivers is at fault, replace with new or reconditioned board, should be ok again, but also check fuses on zsus, and ysus boards, to make sure that these boards are ok first, if fuses are ok, then its deffinately the main board
