Marshall mg15fx no sound coming. only sound i get is buzz when switching the master volume knob. pls help me.
Hi, I have repaired loads of these kinds of amps. The first thing to check is if the input jack socket is still soldered to the circuit board properly. These have a tendency to break.
They all have a dual opamp and a 15 watt power amp chip. Invariably it is the power amp chip that fails IF it is an electronic fault. Both chips can be bought for a few pounds.
The variations, aux input, spring reverb and this, digital effects are extremely unlikely to cause this kind of failure.
At one time anyone with a screwdriver and a soldering iron could fix these, but in the days of health and safety, find someone who knows what they are doing.
It should take half an hour and about £3 worth of bits.
All the best, Chris the Fader.

Make sure you are using this on a three wire grounded receptacle. If you are on an old two wirepower system, have a ground installed in the receptaclel you are using. If you are on a grounded circuit, then exercise your warranty for repair/replacement.

Marshall amp troubleshooting
Does anything happen while you turn the knobs on the amp?
I had a similar problem with a yamaha amp. It turned out a couple of knobs went bad. Soldered new pots and it works fine for me now.
