Projector Overheating & Auto Shut Down – Repair in Dhaka

A temperature warning, a red light or the projector switching off by itself after a few minutes are clear signs of overheating. In Bangladesh’s dusty, humid climate this is very common — and ignoring it can damage the lamp, chip and boards.

Common causes

• Dust-clogged air filter and vents
• Fan failed or running slowly
• Projector placed in a closed cabinet or too close to a wall
• Faulty thermal sensor
• Very old lamp running hot

What you can safely check first

• Keep at least 30–50 cm free space around the vents
• Clean the outside air filter gently (if your model has one)
• Do not unplug the projector immediately after use — let the fan cool it down
• Listen whether the fan is running

Please do not open the projector yourself — high voltage and hot parts inside can be dangerous, and opening it can cause more damage.

How we fix it

We open the projector, clean the full internal air path, fans, heat sinks and optical path, replace failed fans or sensors and test the projector for a long period to make sure the temperature stays normal.
