mike f Posted Friday at 11:36 Posted Friday at 11:36 My Boss LMB-3 has died on me! It’ll only come on if sideways force is applied to the power supply lead. It goes off as soon as this force is taken off. Anyone have any suggestions as to what I can do? Thanks Quote

It goes off as soon as this force is taken off. Anyone have any suggestions as to what I can do? Thanks Crack it open. See what's happening around the power jack. If you're lucky you could reflow the solder joints, if unlucky and the socket is actually broken then it could probably be easily replaced. If super unlucky, and the power socket is attached to a board, the board has had a mischief befall it such as a crack, a broken trace or a solder pad come away. That's less fun. You might be able to bodge around it. Edited Friday at 12:53 by neepheid 1 1 Quote
neepheid Posted Friday at 12:55 Posted Friday at 12:55 From this pic I found online, the socket does appear to be soldered direct to the main board... 1 Quote
mike f Posted Friday at 13:18 Author Posted Friday at 13:18 @neepheid thanks man. I’ve had a peek inside and I think it’s cracked. The soldering around it looks unhealthy, milky white. Quote

Solder joints look solid enough, so my money is on the DC jack itself having failed. I'd replace it. 1 Quote

LukeFRC Posted 2 hours ago Posted 2 hours ago What Neepheid said - solder looks ok, if it's fixed when wiggled its mechanical and needs a new jack socket... 1 Quote
