I wired the original headphone jack in my DMG for postpot prosound and it works fine for a few minutes then just turns off. The battery light stays on, but the system shuts off just like I flipped the power switch. Any ideas?
It sound broken. Get a new one and do it right.
lol.
Remove the mod and check EVERY point where you soldered to. It sounds like there could be a short where-in the circuit is drawing too much power.
I switched out the back board for an extra I had. Good to go.
I had this same problem until i put heat shrink around the solder points of the headphone jack I'm using.
