I have a similar set, the 27A32. My guess is the same TV but a year older. I haven't noticed the problem you are having but did have several caps go bad in the power supply. At first it would power up then turn off, Turn on again and it was okay. Then it took a couple of times, Then it took many times. I replaced a bunch of electrolytic caps in the power supply and it has been fine every since. I think when I checked several years ago the set had something like 18,000 hours on it. I still watch it a little when I go to bed.
EDIT: Boy was I off! It has 31,826 hours in 2000. Now it has 32,767! I guess that seems about right.. about a half hour a day.

Do you have an ESR meter? I wish I would have had one when I repaired mine. I made a list of all the electrolytics in the power supply and replaced them all. Back then, I only had a component tester that would test out of circuit. So, if I removed it, it got replaced. It wasn't a lost cause though, many were high ESR.
