Question about Marshall Mg15dfx 15-Watt Combo Guitar Amplifier

1 Answer

Marshall MG15DFX - Sound cuts out randomly when using distortion or effects. Turning amp off then on solves it only until it happens again. Does not seem to affect the clean channel. Could it possibly be a loose connection somewhere?

There are many things it could be... I often quote the probabilities based on many ears experience and the symptoms the person posts.

Based on what you have posted, there is an intermittent... the unit vibrates while operating... there could be a loose connection, however my guess is you will find bad soldering at one of the pots that control the distortion. The solder often breaks loose as the sometimes support the circuit board from the leads of these pots. Also switches that solder to the board and sometimes jacks for foot switches break loose.

Open the unit and inspect the solder joints. It often takes an experienced eye to spot the tiny grey ring around the solder meniscus that signals a failure.

Marshall Amplification Marshall MG2FX Guitar Combo Amp power turns on but no sound

At this point, I would just take it to a tech rather than poke around in it. It sounds like the power section is the problem as you have guessed, but without the technical knowledge you'd be shooting in the dark. That particular amp is right on the line of being expensive enough that would be worth repairing, but you might do just as wel to check Ebay for another used one.
Good Luck!

Marshall mg 50 dfx amp sounds muffled?

Turn off the effects or go inside and unplug the little sound card. It is only a few samples of real effects, not the real thing. It's like a cheap PC sound card separate from the other components and has a small power plug on it. Wiggle that plug or unplug to see if it changes. It won't cut her sound, just the effects. Make sure the effects are off and verify, if using a footswitch, that it is working properly.

Distorted speaker sound - only 18 months old not played at volume - is it likely to be the speaker or electronic ? Is this a common fault - will it happen again making this amp unreliable ? Not as...

this is a electronic problem. there must be a capacitor/s in the output section that's swollen and will keep giving the same problem unless its replaced.

I have a problem with the digital fx section on the amp. No single effect works anymore, even when the fx level is on maximum..

probably a bad solder joint on the circuit board where that pot is soldered in. check it out and reheat and apply a little more solder. or its just a dead pot.

Mg15dfx Amp issue

Most of these use an amplifier chip in the TDA family of 5 or 7 pin audio amps.

If you play real loud you may overheat the chip and it will go into shutdown to protect the chip.

Sometimes htey don't put adequate thermal conductive grease on the chip causing it to overheat.

Remember this is a small practice amp, not a powerhouse.

It sounds like it is going into "motorboating" as it is called.
