Hi, new so forgive me if I've posted where I should have joined a discussion.

My Marshall VS65R had a problem where the switch [SS 160 3 by rongfeng] wouldn't click when pushed in / unit would power on - red light - then fade.
So I had a look and identified the switch, saw that half of its inner plastic had melted. Not switching correctly.

So I've found a replacement switch [difficult!] which arrived today.

Have taken out the circuit board with a view to installing the replacement and having had a look at it in some decent light can see some discoloured areas [pictures attached].

Nothing that's immediately obviously burned but as a relative newb to electronics I'm wondering if anyone else can have a look and advise if it's fried [probably] or go ahead with the replacement.

As stated it flares on then powers off. Holding the switch in doesn't make a difference.

Any help appreciated / please feel free to point me elsewhere in this forum if I've taken a wrong turn.

Pictures are both sides of the board where it's discoloured + the burnt switch.

Cheers!
