Rear Projection TV shuts down after a few minutes.
Zenith Z52SZ80 will shut down after being on for 15 minutes. We wait a few minutes and turn it back on. It shuts down again after less minutes. We repeat this and it keep shutting down. Lamp indicator is orange indicating the lamp is reaching the end of its life and needs to be replaced. Is it the lamp, only, that needs replacing or is the ballast also a problem? What are the part numbers for the lamp and ballast?

You may have damaged the lamp or the ballast that drives the lamp.
Confirm the model and brand to me:
All sets that use a lamp warn you to if you turn set off NOT to unplug it for several minutes until the fans in set all shut off.
What can and does happen is when set turned off the fans continue (especially the one on the lamp) to run until the lamp cools down to a specific temperature---unplug it before that and the lamp can instantly be damaged or even destroyed.
This tv the high voltage is dead.The FBT,this is a Flyback transformer is dead.The tv must replaced the FBT,it hard and dangerous to do,if never done it before.Hire a tv shop tech. to rplaced FBT,might need to trouble shoot on the deflection board also for other parts also burns.
you can try to shut the tv off ,unplug the power to tv and anything that is powering the tv[pvr] .now plug in the power to the box first wait,30 seconds or so ,now plug in the tv wait,now turn the t.v. on,WAIT unless it starts smoking just wait.see what happens.
Your problem may be solved by re-initializing the set. With the tv on use the remote and push MENU,2,1,7,0. A display will come up. Use the up down arrows on the remote to select INITIAL and press the enter key on the remote. That should do it.
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.
Sounds like a short in the power wire, it takes about 10 to 15 minutes to warm up then shorts out and when it cools down you can watch for 10 to 15 more minutes before it shuts off again, you need to take it in and have the powercord replaced because this is very hard to do from home and one mistake can make the whole tv not work.
Sounds like the lamp to me. The projection lamps get hotter as
they age and the TVs have a sensor to monitor the temp and shutdown the
TV if it get too high
Projection TV makers charge an arm and a leg for their replacement
lamps. They make it easy to do but as a result the custom lamp
assy is expensive. The trick is to buy just the bulb for your
model TV from any number of us aftermarket sources at a fraction of the
lamp price and install it in the old lamp yourself. Really
According to the E44W48LCD service manual, the temperature indicator red light states the projection TV shut down due to overheating. Red (flashing) states the projection TV shut down, check the cooling fan.
