Good evening all

I was wondering if anyone knew if its possible to repair a massoth xls decoder sadly it got a short in the wiring and sent track voltage up the motor wire, its blown I guess the diodes? as the sound, lights power buffer all work perfect put zero control to motors. @ £205 for a new one I would like to see if it can be repaired ?

Cheers

Kind of an ambiguous question, can it be repaired, most likely unless you have blown the microprocessor.

But who will you get to locate the failure and try to repair it?

So, from a practical point, if you have an electrical engineer friend, perhaps he/she can debug it. If not, you could try testing some of the individual components, but you have to know how, and maybe how to solder surface mount devices.

So not simple in most cases, not cookbook procedure to fix. more likely you blew one of the output transistors, since you say sound and lights work.

Might be worth contacting Massoth detailing the issue, they may do a repair for you.
 
Massoth do repair their items..
It will obviously mean it going back to Germany.

Check the website for contact details, and the current procedure.
Do not just send it 'on spec.' as this will delay the repair.

If the lights and sound are still functioning, it does sound like it may only be the motor output stage, that is damaged.

There's a Return Form to Massoth for repairs or warranty support.......see attached. For warranty support, the decoder must have been purchased within the last 12 months, and you must include the purchase receipt with the shipment to Massoth and they will repair it no cost, or replace it. If over 12 months, you will be charged for the repairs; you also will need to pay for the return postage for both services. The shipping costs from Germany to the USA for a small package of one or several decoders is about 35 euros.
