I just got my Samsung PN42B450 last night from Sears. After about 3 hours of watching it, I started hearing a buzzing and clicking sound from the rear. The sounds went away, but an hour later the tv started shutting off the restarting. It did this about 4 times in a row. I shut the tv off. Now this morning the tv only stays on about 15 minutes, then shuts itself off. This is very frustrating.
I called the Samsung number on the manual. The woman sugested it was my cables. I'm using a Directv HD into the tv via HDMI. The same setup I've used for years with my Panasonic rear projection LCD with no problems.
Anybody have any ideas???

Your panel is defective. Have sears exchange it for ya.
Cable connections wouldn't cause your panel cycle power.

thanks Paul, that's exactly what I did today. I have my new plasma and all is well so far!!!

Good. The best thing to do with any problem found immediately upon purchase is to exchange it, assuming all connections are correct.

Enjoy your new plasma
