Title: MLT666 REV 2.8
Post by: scooby-doo on March 29, 2012,16:44:57

Hi

Got a TWF 32 with MLT666 in it...strange fault when plugging the cable in, get the front led lights up,flick the switch it just dies and light goes out and its completely dead
No voltages from anything on the psu....main fuse is fine..I know these suffer from blowing the fuse but this one seems ok and no shorts from fets

All caps "seem" to be ok on ESR and bulginess

Any help chaps and chapesses appreciated

Errmmmm Note to self

Make sure you check for a 240v supply at the power point then the switch before trying to get a voltage at the board.

Flick switch is fluffed all sorted now.

Cheers
