Default KSA-50S no sound problem- please help

Hi all,
My brother just bought a Krell ksa50s off eBay.
It's DOA. Amp start up nicely, click relay and all bias led are on - then after a while the led go off pair by pair - We connect with balanced inputs but no sound. We also try with RCA ( with jumper on 1/3 of XLR) still no sound
No smoke or smell come off the amp. It's start up sequence seem ok.
Any one think off any simple reset that I can revive it. Or any internal fuses that need to check? Input board toasted?
Your comments really help before we send it back to seller, or to Krell
