Anyone know anything about digital sound systems on the blink ?

Hey people . l've got a nice little Yamaha digital sound system that's gone on the blink. It's the little mini style.

It's about 2yrs old and the power turns on , but then it turns itself of again after about 30 seconds .
That's it , that's all it will do.
Doesn't make any dif' what you set it to , radio , cd , usb whatever . You get just enough time to pick a setting before it will just go off again.
It doesn't make any noise or click , just turns off.

Would you have any idea what that would be , is there anything l can do or will l need to take it in. Would it be a simple fix for them or something big ?

It's been a great little system , great sound , paid about 1500 for it.
 
Sounds like the power supply is getting hot and thermal cutout protection is kicking in. Just a possibility wouldn't know without looking that it. Could be a power supply or a a fan or just needs a blow out. Take it your local electronics repairer a quote shouldn't cost much.
 
Gee ,thanks for that james , that sounds exactly like what it seems to be doing .
l've just moved to but l know it's position in the other house where it sat for 2yrs , was always extremely dusty. l was always cleaning of the top of the system .
