Title: Help! Blew Something In Charging Circuit Sl-6000
Post by: witzgall on February 01, 2009, 11:53:29 am

HI all;

In a momnetary lapse of judgement, I attached my SL-6000 directly to a 12v power source. The screen got brighter, and then a pop. The unit still worked while the battery had juice, but it won't accept a charge. I imagine there is a fuse or capacitor blown inside, but a look over did not spot anything obvious.

Does anyone have any insight? I don't do small board sodering, but I know people who do, if I can get them pointed in the right direction.

Waiting hopefully,
Chris

if you're in luck then you only blew the surface mount fuse on the board.  I don't recall anyone having to repair a Tosa's fuse, but there's quite a few people who've done if for the 7xx, 8xx, 1000 and 3xxx, just need to search forum for those threads and there's going to be a picture of a fuse somewhere

It would be worthwhile to test a different battery.  Li-ion batteries have an internal safety circuit, so you may have blown it.  I would try that before even considering replacing a surface-mount fuse.
