digilogic dstb 1000?

Hi, we bought this a few years ago but only use it now as we have to! Only use it occasionally in bedroom in mornings. Put it on the other morning and there was no green light, so no power! We checked fuse in plug, batteries in remote, scart leads etc. Any ideas whats wrong with it please?

Its quite bad really considering its not really been used very much.

Are there any chances of replacements or refunds on something this old?

Thanks.
