Yes..This is most likely the LAMP, But it could also be a thermal sensor. You should first try a new lamp (which you will have to get at some point anyway) and if that does not fix it I would call a professional.

I have a Infocus in1503. It shuts down after 10 to 30 minutes. When it does shut down there is no lights. In fact the power light goes off as well.


I seemed to have had the exact same problem... I had placed the projector on top of a small book (to raise the unit), however, did not rest the feet of the projection unit on the book and it overheated and turned off, as a result. (The bottom of the unit was making direct contact with the book which caused it to overheat since not any air was passing through between the two)

After letting it cool for a while and powering it up -- it would usually power off completely for about 15 minutes. After a little thinking, I thought it may be the lamp/bulb and waited a couple of years and bought one online that arrived yesterday.

I installed the new lamp/bulb this morning and it did the same thing. It powered down about a half hour later. Bummer.

I reset the machine to factory defaults and checked to see if it had the 1.03 firmware... It did

Then went through the settings in the setup area and turned off the 'prevent pic screen saver'... Reset the 'lamp hours'

I doubled checked the lamp/bulb installation... Turned it back on -- same thing -- it shut off after about 15 minutes or so... Then unplugged the unit and turned it over and took out the 4 or 5 chassis screws and loosened and took off the side panels and blew onto the fans and circuit board areas and gently pounded the sides to shake anything that shouldn't be there loose and put it back together.

i powered it back on and now it's been working for about 2 hours and 16 minutes!

good luck!

I HAVE AKAI PT50DL24XISMS IT COMES ON FOR 30SEC TO 1MIN THE PICTUREGOES OUT THE SOUND STAY ON THEN GOES OFF


Its a DLP that uses a lamp, lamp is possible but I would also look to see if fans are on and running, a fan stopping or even slowing down can trigger the set off also.

Average lamp life is 2000 hours or two years and set if lamp a bit dim may shut set off.

Lamp Fan should not cut off and on it should run at all times when TV is Turned on.Lamp Fan is designed to run when set is turned on to Keep Lamp Cool otherwise Lamp will burn up.
Yes Bad optical unit block could also cause set to shut down.But most of them will Play but with Dots,Green yellow tinit or Big blue Spots

TV goes off after 20 seconds Samsung HLS5086wx


First Take off the Lamp Door and replace it back the way it was secured with all of the screws. Doing this will reset the safety interlock switch which heats up and opens the circuit causing the set to shut down. After doing this and the set still shuts down check the lamp. Depending on the amount of hours on the lamp it may be a bad lamp. They will fail with out any obvious signs. If the set shut down and goes straight to the Stand By condition then you have a bad Power Supply. If you hear a whining or buzzing sound then you have a bad Color Wheel.

My benq projector turns on for a few minutes (light and fan going strong), then it shuts down.


if it goes through shut down mode (lamp first and fans run a while), reset the settings to factory default. while you're in the menu, check the lamp hours (under settings). if they're close to 2000 hours, replace the lamp. if the projector shuts down immediately, fans and all, you have a power supply problem. you'll need to replace it.

Tv will go black sound will last a few seconds. It resets and starts for a minute or so. other times it will run for hours with no issue. Some times it restes more just on start up and after it warms up...


If the set shuts down and cycles 3 times before the set goes to the 3 flashing lights on front, I would suspect the lamp causing this issue. Each time the set restarts on its own it boosts the voltage to fire the lamp and after 3 times it's basically 3 strikes and you're out. If you haven't replaced the lamp in a long time then suspect that first.
