Hi Group, can someone help please?, This Sceptre 55 inch tv can to me with no backlights, I repaired those and they are working fine. Now i have a faint blue screen, no pic and no signal, I have no remote, the only button that works is the on/off. I replaced the main board three times, along with the tcon board, no results. there is proper voltage to the main board. I tested the fuse on the tcon bd and there is 12v. no voltage on pins to the ribbon cables to the panel, they are all less than one volt. any help in this matter will be taken seriously, Thanks.

Stan..
