I don't usually bother with stuff this small, but I will look at these for customers I've had for years.
I have two MD13P1s in the shop that shut down within a couple of seconds of start. The raster looks fine before shutdown occurs. Customers say sometimes it will run for weeks with no problem. The other one is now running on the bench. I wouldn't ordinarily bother the group with this except there is quite a pattern developing on these.
I have another customer who picked one up from my shop a couple of weeks ago (same complaint, although it's a 14" flat version) that didn't show a problem in the shop, but is now shutting down again. I did some checking on the web, and found a post from a guy who has two with the same problem, and one was already replaced in warranty for the same problme, so he's had three with the same problem! Cut and pasted from the web:

-------------------------------------------------------------------------------- Date:4/7/2005 Subject:Toshiba MD13P1 Turns itself off
Question I own two of these tv/dvd sets, they are in different rooms and both have the exact same problem. It started suddenly turning itself off instantly after turning it on. I could not figure it out so I took It back to the store where it was purchased and they traded it in for a new one. I thought the problem might just be a fluke and I liked the tv set so I also bought another one for a separate room. Now both of the new ones, (3 mo. old) are doing the exact same thing. I turn the sets on and they instantly turn off, I've tried unplugging them and plugging them back in, and they stay on for about 15-20 seconds and then turn off again, then I try it again and they turn off instantly.

I suggested to one of my customers that he contact Toshiba and see if there is a known problem, and of course "they have never heard of this problem. I'm half tempted to order the schematic for this model, but I really only do these loss jobs for good customers. Anyone here run across these?
