Audio aero capitole mk2 need help repairing

Dear: friends,

I have owned this great mk2 cdp for years, recently problem starts to appears, it switches off by itself and turns back on again while playing, and this switching on and off wont stop untill i have to power down the unit and let it rest for a few seconds before turning the power on again. However, this happens in sequence like after a few minute again while playing. It keeps on switching on and off by itself while playing.

I really love this aero, one of the best, most intimate, detail and warm digital player, and it is hard for me to find a replacement, so i would kindly seek help on similar problem and resolution to repair this...

Pls help...thanks alot and I would appreciate any advice....
