WDTV loses signal midplay constantly during play mode

Overnight my WDTV unit decided to start losing its signal during movies, but then comes back on again within seconds. Very annoying trying to watch a show. Never has this issue before, and seems to be the same with avi., or mkv movies. Does it with new movies, as well as older ones that never did it before.
I am hardwired, do not use wifi.

Ideas? I did factory reset, plus also pushed the little pin on the side to reset, but same issue.

This could be a router issue, and the WDTV is momentarily loosing its input signal. The WDTV could be perfectly fine. Check connections, cables and reboot router to see if things improve.

Sorry, I guess I did not mention its running off USB stick, not plugged into router.

And its the same USB stick for last year almost.

If it is a slow USB stick, that could be a problem; maybe the USB stick has gone bad. Try using another USB stick.

Hi
My unit has started doing the same thing, generally after 40minutes, goes off/on like mad for 30 seconds and then calms down.

Going through a router, replaced cables, rebooted - no change.

Dusted the fan off, improved air flow around unit, still the same.
