Oppo BDP-103 won't turn on

Hi! I had a lucky find at Seattle Goodwill - Oppo BDP-103 for $24.99.

When I plug it in the tiny light on the far left of the front panel glows red but other than that the unit is completely unresponsive. No other lights come on, no sounds of moving parts. Pressing power button does nothing.

I opened it up to look for obvious signs of damage and didn't see any...no bulging or leaking capacitors, no water damage, no scorch marks etc.

Any ideas on what might be going on? Thanks in advance! -Joe
