Found a blown fuse at the top of the BM3 board. This board as 10 fuses on it, some as small as a pencil point!
After repairing the fuse, all I could get was lines. Still can't get sound thru it or see any channels that are selected. Still appears brain dead.
I read a post somewhere where someone bought a new BM3 board and it worked for ONE day then quit doing the same thing!
Some of these are better left on the roadside!
