Retro Duo A/V ports no longer working. How do I fix it?

It seems that my Retrobit Retro Duo video outputs got killed by a power outage this weekend, along with my auto-sensing A/V and S video selector switch. It still seems to power the slots (as in the lights still work) but I get no signal transmission, and I know that it was working a few weeks prior to the power outage and was working fine. Is there a way for me to repair it or will I have to replace the console?
