Projection lamp shuting down

Projection bulb shuting down then coming back on . Thought problem was not enough air flow due to a fan not working but fan was ok.We have four of these in a sports bar,I have replaced lamps in them but have not seen this problem. I am a electronic tech for nasa. Any help would sure be great. Unit may run 3 or 4 minutes or may run 10, there is no set pattern.

I experienced a similar problem with my Sony KDFE60A20, the projection bulb would turn off for about 90 seconds and come back on for the same amount of time then cycle off and on for about half an hour. I cleaned the circulation fan in the rear turned the tv back on and it was ok for the rest of the day. It started all over again the next day so I then took a look at the bulb, I found that the bulb has a venting/cooling screen at the top and bottom of the lamp holder, the top screen was plugged with dust, cleaned it and put it back together and the problem has been resolved now for 1 week. Seems like the problem has been resolved. Tv is exactly 18 months old and is connected through an APC UPS Backup.

I had this problem and ordered a new replacement XL2200 lamp from Sony and that fixed it. By the way, the lamp installs from the front so there's no need to pull your TV out from the wall. Look at you manual, it is accurate in this respect. My lamp only lasted about 15 months. It costs $200 plus about $16 to ship. You can order direct from Sony on line service.

Confirm if this is happening during explosions screenshots or high white tones images. I noticed that my set goes black immediately after an explosion or during commercials (Essurance commercials for example). I'll have a technician tomorrow to replace the power board (another problem), but I'll also show him my observations to get his feedback about the blank screen...will let u know!!!

I have a mitsubishi 1080p wd-65731 just replaced lamp , tv comes on works fine for about 30 minutes and then shuts off , cleaned vents good , has good air flow light that says lamp turns red in the fr
Could be the fan. It will cool tv but could also be to much for tv to handle.
You can also try reseating the lamp. It may say ok but be wrong.
I have a Mitsubishi 5500 projection tv . have had the type of issue you have had and I have replaced a lamp as well.had to reseat the lamp three times before it worked without shutting down.
Hope this helps.

My first thought is not enough air or coolant flow at idle.
I would check air flow thru the radiator and coolant flow from the water pump. Are you sure the cooling fan is coming on at 220 degrees ?

My xbox keeps shuting down due to ventalation issues. Ive tried to clean the system with an air dust remover but i still keeps shuting off. My fan runs super fast all the time too.
Most likely, you have your Xbox in an area where it does not receive proper air flow and ventilation. Your fan is overworking itself from the dust and the heat of the area you're sitting it in.

Try moving your Xbox to a more open area after cleaning it, and be sure to let it dry out after using compressed air.

Line and air flow box between freezer and frig freezing up, we took apart, defrosted . air comes into frig, but still not cool enough. freezer works great This is a side by side model # ED25PWXAN01
If the fan is running in the freezer compartment, temperatiure is normal, and no frost is building up on the back panel in the freezer panel, then there is a good chance the return air shutes in the fresh food compartment are blocked with ice. The return ducting is just as important as the the supply shute which you melted out. Difficult if not impossible to see.
My recomendation is to empty, unplug and air dry the whole machine preferably with a fan blowing air into the fresh food compartment.
Haste makes waste with this machine. Using heat can cause the plastic shutes to melt and distort.
Should be defrosted in this manner for 24 hours.
Restart and give the machine 24 hours to recover. Common problem with Whirlpool products.
P.S. Check to see if lights go out when closing fridge door. In fact this should be your first step. Jack

Screen going black Sony KDF-E60A20
Remove the lower front panel by removing the 2 large round screw heads at the lower back corners, one on each side. Remove the retaining screw on the right side of the metal horizontal retaining strip in front of the bulb holder, remove bulb retaining screw in the upper left corner of the bulb holder. Pull the bulb holder out towards you and check for dust build up on the top screen on the bulb casing, if there is an abundance of dust it will restrict the airflow across the face of the bulb which causes it to heat up and turn off. Once the dust has been cleaned your bulb should now work as it should without a problem.

Cooling
Check if the condensar ( outside fan unit) is getting enough free ventilation. IF there is no free air flow you will mostlikely be triping the unit due to short cycling. Ie the unit is pulling its own discherge air causing the compressor to trip due to high back pressure
