My Daewoo 9503TFP periodically shuts down briefly and switches on again. If it's in the process of recording, it starts recording again when it comes back on, but obviously there's a break in the recording.

I have formatted the hard drive and checked for a possible software update (none available) but still the problem persists.

I can be doing anything from simply changing channels to fast forwarding a recording. It very briefly flashes up a grey box with some confirmation or other about the hard drive (I think it's the same one I got after formatting), then I get a green screen and a re-boot. It even does it overnight during an unattended recording.

I'm sure I've heard of it happening with other similar boxes, but is there a known remedy I can implement, or an upgrade which I can get hold of?

I found a huge Daewoo thread on Digital Spy which contains posts about your problem (I haven't gone any further into it, that's up to you ):
