RE: Jamman Help!!!

[Mike Steck <british52@yahoo.com>]

thanks for the direction....I tried another wallwart and it does the same thing....the red display flashes for a moment...all the led's light for that same second..then it goes dark....and stays that way..

so its not power up to the unit....and power reaches some of the internals to light it briefly....

 

do chips just simply give up over time....?

mike- your best bet is to try to find a decent local tech & put him in touch with bob sellon somehow. I'd be inclined to suggest that if it's not lighting up at all, ever, then the problem will be with this (internal) power supply mechanism we've just been speculating about....

 

but can you get a voltmeter onto the external psu & see if it's still kicking out the 9V ac? sometimes these wallwarts fail where the thin wire goes into the transformer or the connector..... otherwise, it may be this voltage doubler or the main 5V regulator.

 

if you've got a line6 power supply anywhere close (maybe someone you know?) then try that on the jamman- they also run 9V ac. I have used them many times in the past on our two jammans.

 

I aim to have mine in bits soon to dig a little deeper into replacing the wallwart, but this won't happen for a couple of weeks.

 

good luck!

 

duncan.
