Mistub XD450. Bulb relatively new. Projector


Does the projector work normally when sitting right-side up? If yes, something could be interfering when the unit is inverted. The symptom you describe initially sounds like a defective fan (some fans put out a computer pulse telling the main board it's running--they have 3 wires, red, black, yellow(signal)). If the board doesn't get signals from all required components, it's programmed to shut down to protect itself.

Boxlight CD-725C TEMP light comes on and unit shuts down afer 10 minutes. Unit has about 1200 hours on the bulb. Seconds before the unit stops, at least one of the fans slows down.


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.

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.
