Question about Vizio Televison & Video
Replaced Power Supply board, Main Board, Tcon Board and ribbon cables to and from Tcon board and cable harnesses from Power supply board to Main board. Same result. No Picture, Backlights on, Audio works. Checked voltage on ribbon from Main to Tcon and 12.5 volts on both ends at solder point 1 and solder point 51, respectively. No voltage to ribbons leaving Tcon board either side. Checked Gate and Drain and Source on Tcon Board and 0 volts. Any ideas now? or did I get sent a bad Tcon Board.

If you see the back light, then you should have 24vdc on the main power supply board which it gets the turn on command from the maun board. If you do have all those voltage, then it does sound like you need the new main board.

LCD simple panel check. In a dark room, (does not have to be total), shine a flashlight at it with a station tuned in. If you see images
and you have changed the panel HV board, your flourescent tubes could be bad. If you dont, then check the cabling.
