How can i fix my Sharp VCR/DVD Combination?

I have a SHARP VCR/DVD Combi, model number DV-RW360H. When i tried to take the system off standby it seems to have frozen, i have the power light still on standby and the DVD/VCR lights turned on, but nothing else, no clock or anything. I have tried unplugging it to try and reset it but that has had no effect at all.

Any idea's on how to reset it?
