Hello Matt,
this is a fault of the 4013 flipflop (IC1) on the
card. I had this fault many times here in my shop, and I think it is caused by
age somehow. The LED of PRG 2 - 4 will light while you push and hold their
buttons, but if you let the buttons go, only PRG 1 will stay,
right?
You have to solder a 100k resistor between pin 3
and 7 and then it should work like a charm. Don't replace IC1.
Best
Michael

Hi Guys,
I have an SDS V & recently both of my Tom cards are refusing to change from the factory settings.
Is there a easy fix for this?
Does anyone know what will have caused it?
Cheers
Matt
