My x6 infocus does not react to the remote control

Question edited for clarity.

This doesn't appear to be a known issue, so my view is that the remote has just failed. Try the smartphone forward facing camera trick to see if the remote is producing an output signal.

lamp fault i say..

There are a few possible causes for a projector like the Infocus IN2124/IN2126 turning itself on and not being able to be turned off with the remote:
1. Remote control issues: Firstly, it's worth checking the remote control itself. Ensure that the batteries are fresh and properly inserted. Try replacing the batteries or using a different remote control to see if the issue persists.
2. Signal interference: Sometimes, external factors can interfere with the projector's remote control signal. Check if there are any sources of interference nearby, such as other electronic devices or strong light sources. Move these items away from the projector to see if it resolves the problem.
3. Faulty power button or control board: It's possible that the power button on the projector or the control board itself is malfunctioning. If the power button is not responding when pressed, it could indicate a hardware issue. In such cases, contacting Infocus customer support or a professional technician for further assistance or repairs may be necessary.
4. Firmware or software issue: Occasionally, a software or firmware glitch can cause unexpected behavior in electronic devices. Check if there are any firmware updates available for your projector model on the Infocus website. Updating the firmware can potentially resolve any known issues and improve overall performance.
5. Power supply issues: In some cases, fluctuations or problems with the power supply can cause erratic behavior in electronic devices. Ensure that the projector is connected to a stable and properly grounded power source. Consider trying a different power outlet or using a voltage stabilizer to rule out any power-related issues.
If the issue persists after trying these steps, it is recommended to reach out to Infocus customer support or consult a professional technician with expertise in projector repairs. They will be able to provide more specific guidance and troubleshooting steps based on your particular projector model.

Check the lamp.or more details: http://www.aboutprojectors.com/InFocus-X6-projector.html

try mo po icheck ung lens nyan o kaya po sa cable

could be either the colorwheelor one of the fans. checkthe fans for obstructions. otherwise, replace the colorwheel.

the sensor window may be blocked with dust. clean out projector with canned air.

it there is no high-pitched squeal when it starts up, the colorwheel needs replacing. the lamp won't light without it. the part is under $50, but installation is quite involved.

good luck. infocus has nothing having to do with any of the lp4xx series. they don't even have lamps. try ebay.

A bit unusual for the projector to stop responding to the remote. Usually it follows when someone has opened the projector, they forgot to reconnect the controls from the case top which also includes the IR receiver. If it isn't that, it could be a broken IR pc board or bad connection. I've seen that.

The worst case is that the IR controller on the main board has failed and if that's the case, you'll have to live with it as the cost of a new board is very high.
