zoom power problems

[perutxo]

Hi everyone,

It seems that my zoom pedal suddenly needs more A than usual. When I plug the 300mA adapter, it says battery is low and it wouldn't start, but when I plug another 1500 mA Ihave, then it does work, but the unit heats up like hell. I opened the unit and found that close to the power in section there's a little "sausage like" resistor? capacitor? that heats up like hell (I actually burnt my thumb when I touched it) and also the processor heats up.

All this happened after I lent the unit to a friend who says that it just suddenly stopped working while using the 300mA adapter. I think he might have used phantom power (he doesn´t know/remember) and that might be the cause of the problem.
Sending the unit to be repaired would cause more expenses than buying a new one (this latter option not available either), so do you electonics seers think that I could fix it, bearing in mind you know what the problem is???????


Thanks
Thanks

Can you get pics? 'Sausage like' and 'burns at the touch' are definitely not good things. Sounds like you should be able to repair it if it works now (sort of), but identifying the right components to change will be tricky. Pics will help.

Hi perutxo.

Your pedal needs to be repaired by a qualified technician.

These are ZOOM's two distributors for Spain. Please contact one of them re your pedal's problem.

Considering the OP lives in the Canary Islands (a Spanish dependency more than 1000 miles away from Spain), I guess going to mainland Spain to get a Zoom piece repaired will be difficult.

I don't have any ideas, though. It's a bizarre problem. When I fed my B1X a 500 mA supply, it didn't work. I'd actually had confirmation from various sources (one example: http://216.57.203.36/showthread.php?p=38005618#post38005618)that using a power supply delivering more than required amps is not going to hurt it. Though there was no harm done, it didn't work.

In my knowledge if you use a supply delivering less than required amps, that problems .

In my knowledge if you use a supply delivering less than required amps, that causes problems .

Here's one. Check the Source link I provided to the OP. Here it is again:

BTW. Pedals can be shipped--as I'd expect that everything which goes to or comes from the Canary Islands would have to be.

OP's asking for a reason as to what is causing the problem. For some reason he does not seem to want to buy a new one or send this one for repairs to the guys at Zoom/Samson. What he's asking for is probably a quick fix, which is possible I think.

I leave this to someone who can give ideas regarding what in the electrical circuit could be causing this.

FWIW, being as cheap as they're, Zoom pedals might have defective, dodgy circuitry (some pieces anyhow)

...tells me that the OP lacks the electronics background to effectively and safely troubleshoot & repair the issue with his ZOOM pedal.

One of the distributors in Spain may have an idea of what is wrong with the OP's pedal and/or may be able to recommend a local electronics repair shop.

As well, since the OP didn't mention when he purchased his ZOOM, it may still be under warranty. Foreign distributors usually handle warranty and repair work on U.S.-made products sold in overseas markets.

Hi perutxo.

If the two distributors in Spain can't help you out at a reasonable cost then - as a long shot - you may wish to try posting the details of your ZOOM pedal problem here:

All other Zoom Gear and Zoom Talk

[perutxo]

Thank you very much for all your answers. however I just ordered the new zoom 9.1ut, so for now, I won't get the other one repaired. I really appreciate your help though.

Thanks a lot
