Check for shorts, blown fuses on ysus, if blown replace entire board, easier than locating many of the parts installed on the board.

7 red flashing lights, won't power up..


Check the power board for capacitors with the tops bulged up. They are 3300uf 10v. There are either 2 or 4 of them depending on your set.
