Question about Zenith Z52SZ80 TV

Zenith dlp projection t.v. model#z52sz80 t.v. turns off randomly

Iur t.v. has begun to turn off randomly for no reason in the last week or so. Sometimes it will turn on and stay on for a few hours and sometimes it turns off in ten minutes. We are frustrated and would like to know if you know what it might me. The lamp light will blink red when it turns off and then as soon as the red light stops blinking you can turn it right back on and it runs perfect again but you never know when it is going to turn off.
Please Help

    I am having the same problem with my Z52sz80 TV. It will randomly shut itself off, after the red light starts blinking? Do I need a new bulb, or a new module or both?

    zenith z52sz80, shuts off randomly, red light blinks 7 times then stops, then i am able to turn the tv back on. i have already reset the lamp timer and cleaned off the fan, but am still having the problem. Called Zenith tech support and all they said is for me to have a professional come out and service the unit. any input would be greatly appreciated.

This solution is for the zenith 56" DLP. Unplug the tv, either from the wall socket or the TV. While the TV is unplugged hold the power button on the TV for 40 seconds. This lets the excessive power drain from the TV. If this does not work call 1-800-243-0000. This is the number for their help line. This is the fix the tech gave me and it worked right away. Hope this helps and have a great day.

Same problem, TV runs fine anywhere from 10 Mins to 30 then cuts itself off. After the first shut down the time between shut downs consistently speeds up. Power button hold and fan cleaning techniques didn't work for mine and would love to fix this problem. HELP PLEASE
