Whats Wrong?????

[dust2dust]

something is shorting,maybe it has blown a fuse now maybe not

solder ball moves and causes short or wire come off and is shorting is main things i can think of

my advice is to leave it alone until your installer returns
the more yuo use it the more chance of blowing a fuse,blue light not on it could possibly of blown the ba58 chip or the fuse to it
