power failure on a panasonic dvd/vcr recorder (dmr es30) can it be repaired?

i appear to have a power failure on my above dvd/vcr combi. The power came on yesterday, for a short while, then switched off without touching it. Today nothing. When the power came on yesterday the machine worked perfectly. I have changed the fuse but the power still did not return. Can it be repaired and is it worth it? The machine is 2 1/2 years old.
