Definitive tech Pro sub 600 auto on issue

[abundant2]

Hi there,
I have a Def Tech Pro Sub 600 and it will not come out of sleep.
If I toggle the on/off switch repeatedly, it will trigger it to come on but after 30mins it switches off and wont come back on.
Have tried all the inputs with the same problem.

Anyone has the circuits? Ideas how to perhaps by pass it so it always turns on?

Thanks
Andy

It sounds like a power supply problem. I had an old dell computer from the late 90s with a bad power supply and it had the exact problem that you're describing. It turned out that a capacitor was going bad on the board. Id check the power supply first.
