Infocus 7210 - won't turn on again after use

I have an Infocus 7210 with only 100-200 hours. We use it only about every other weekend for a movie and consider it a real treat.

3 uses ago I could not get it to power up and the manual suggested unplugging it for a minute and then plugging it in again. This has persisted on every use. Once it powers down I cannot get it to power back up without unplugging it. The extended warranty I have is up in 2 months and I am considering sending it in though I would prefer to not have to. Anything I could do? Is this a known defect?

Thanks,
Tom

Wow .. thanks!
This seemed to work. Wonder why? It was able to power up and off and up again off the remote without a problem. I'll try again later to be sure. Maybe saved some time and $ sending it in.
