Toshiba DVR-670 won't stay powered on - any help?

Everyone,

I was hoping you could help out with a problem with my parents' Toshiba DVR-670KU combo DVR/VCR. A few months back, it started only powering on for a few seconds, then going back into standby. I finally pulled the cover off too look at the components (and get the VHS tape out), but didn't see anything fried or any leaky caps. The +12V out from the power supply seems ok. The large power transistor isn't shorted.

I saw elsewhere that these were made by Funai and that many Magnavox models are similar. Are there any particular problem areas with these, or should I just start checking out transistors, diodes, and the like?

BTW, I noticed a decent hum from the power supply board when I had just the board plugged into the outlet.

Thanks for any help!
Brian
