xenon pro xa840 karaoke amplifier

[peterpan271]

need schematic diagram of xenon pro brand karaoke amplifier model xa840.

unit do power-up but no sound. dial lights all ok. I noticed that upon power on the two DPDT relays do switched on but immediately switched off. checked already the power transistors and the pre-amp trans, all ok. suspects trouble in the other components.

any help?
