Hi, I'm hoping someone might be able to give me an idea of a fault that has developed with AV8. When the processor finishes initialising there is a sudden loud bang through the speakers & the processor powers off. I took all other components out of the equation & just powered on AV8 & same thing happened minus loud bang as power amps were off. I'm presuming that it may be a power surge in the processor & it is powering off to protect itself. Frustrating thing is it was only fully serviced by Arcam 4 months ago & has just gone back a second time to them after they claimed they had sorted it(found a burnt out relay). The fault appears to be triggered by the multi channel input, as if it comes on on the DVD input , cd etc, it works, then press dvd-a input it goes off & then when it turns on after this, once initialised, suddenly turns off again. Incidentally, I've also tried it on other electric rings in the home & it does the same thing Any opinion or advice greatly appreciated.
