Hi, I am a newbie here. My friend has DS7 for a repair, it looks like someone already tried to fix it. Some traces burned, switch broken. I resoldered LED - look ok now. Dry signal goes through but no change when engaged (jumped broken switch) LED brightness remains the same. I have checked resistors and capacitor close to the switch so far ok.
Any idea from where to start?
