Before going through the expense of replacing the fan(s); I removed the covers, bought a can of compressed air and blew out the entire interior, paying special attention to the fans. The projector has worked flawlessly for almost two months. The fix took less than seven dollars and about 30 minutes to complete!

The reason why the temp comes on because the fan is start slow down, so the bulb produce a lot of heat. Once the maximum temp reach, the temperature sensor will become inactive. So boxlight shutdown. First you need to replace the fan, or check the supply dc voltage going to fan if it is stable.

Danby DFF282WDB stopped cooling - light comes on - any troubleshooting we can do?


Hello;

My name is Peter. I am a retired field service refrigeration technician.

You are locked into the defrost mode. This is when every 8-10 hours your unit will shut down for 20-30 minutes and your defrost heater comes on and defrost your freezer cooling (Evaporator) Coil. During this cycle everything shuts down except for the light.

Your controls are usually located on the top of your fresh food section. On the bottom of your controls, near the front, left hand side there is a round hole. This is where your defrost timer is located.

With a large flat head screw driver turn clockwise. You will hear a clicking sound. Turn slowly one click a time until your unit turns on. This unit will have to be replaced. Until it is replace manually turn it off every 10 hours for 20 minutes.

I have a BenQ PB 6210. After switching it on, it first displays that the lamp has run 2001 hours and should be replaced. After this window disappears, it takes maybe 2 seconds and the projector shuts...


Hi cholthusen,

Please be informed that the average lifespan of a projector's lamp is around 2000 hours. The light bulb is almost certainly the problem. The best solution would be to change the bulb. The easiest way to do that is to change the lamp assembly (fresh bulb is in the new assembly). You may also try resetting the unit. Turn the unit off, then physically remove the power cord. wait for about 10-15 seconds then start it back again. If this did not work, please replace the lamp.

Hope it helps.

Thank you for using FixYa.

Projector keeps shutting off and red light comes on


We had a projector at our church that was hooked up to a light switch to turn it on or off and it kept burning the bulbs out. We had an expert come in and look over our situation and he said When you are finished with the projector let the fan keep blowing until the unit cools down. Ours had a switch for the bulb as well as one for the fan. We turned out the bulb and left the fan on for an extra ten to fifteen minutes. That let the bulb cool down gradually If you just cut the power the bulb over heats and will burn out. Yes turning on for a few minutes will burn it our quicker as well. Hope this helps.

Boxlight cd-850m won't turn on


You must reset the lamp timer after you replace the lamp before the unit will turn on. Do this:
Power on the unit. On the projector's keypad, hold down the the two volume keys simultaneously for 10 seconds. At that point the LED will turn green. Now you can turn on the unit again and it should work.

Replaced lamp in optoma ep1690 but there is not projection


Hello, many of times this is related to the brighter being turned down and we go about trying to turn up the unit thru the remote and you may need to do this adjustment directly from the panel on the unit.
If this should fail, you may need to unplug the unit and allow it to be off for over 24 hours and this will cause the unit memory to return back to the manufacture's settings and if you still get the same result, consider your lamp may have played out, need to be replace... good luck and I hope thi helps.

Viewsonic PJ556d shuts down after 30-60 seconds


My solution sounds dumb, I had the same issue. Took the lamp cover off the bottom. The screws were loose holding in the lamp. Maybe they heat and expand and eventually work their way out and the lamp doesn't make good contact. Just tightened mine up, the unit would power off after 45 minutes prior. Been on now for 5 hours, no trouble.

you have the same problem I have. The problem is fixed by changing the new light bulb. The problem appears again after 1500 hours of use. You can keep buying new light bulbs or avoid it by not buying another Samsung TV.
