Frequently Asked Questions - EH505-B OPTOMA
How to clean the air filter of the OPTOMA EH505-B projector?
Turn off the projector and unplug it. Remove the filter cover on the side, take out the filter and clean it with a vacuum cleaner or with warm soapy water (dry it completely before putting it back). Replace it every 500 hours of use.
How to replace the lamp of the EH505-B projector?
Turn off the projector and wait 30 minutes for it to cool down. Unscrew the lamp cover at the back, disconnect the connector, remove the old lamp, insert the new one (part number BL-PL200), reconnect the connector and screw the cover back on. Reset the lamp counter in the OSD menu.
The projector does not turn on, what should I do?
Check that the power cord is properly plugged in and that the outlet works. Wait for the Standby LED to light up. If the LED blinks red, the lamp may be defective or the thermal protection has been triggered. Let it cool for 10 minutes and try again.
How to connect a computer to the EH505-B projector?
Use an HDMI or VGA cable. Plug it into the corresponding port (HDMI 1/2 or VGA IN). Select the appropriate source with the Source button on the remote control. If no image appears, check the computer's resolution (max 1920x1200).
How to adjust keystone correction?
Press the Keystone button on the remote control or go to OSD menu > Image Settings > Keystone Correction. Use the arrow keys to correct the vertical (±30°) and horizontal (±30°) distortion.
The projector displays a 'Temperature too high' message, what should I do?
Turn off the projector immediately. Check that the air intakes and exhaust are not obstructed. Clean the air filter. Ensure there is at least 30 cm of free space around the projector. Let it cool for 20 minutes before turning it back on.
How to update the projector firmware?
The firmware can only be updated by an authorized technician. Contact OPTOMA support or visit the official website to check for available updates. Never download unofficial firmware.
What is the recommended projection distance for a 100-inch image?
With the standard lens (1.6x zoom), the projection distance for a 100-inch diagonal (16:10) is approximately 2.5 to 4.0 meters depending on the zoom setting. Refer to the projection table on page 12 of the manual.
How to use the automatic standby function?
Go to OSD menu > Operation Settings > Auto Standby. Choose Enable (delay from 10 to 60 minutes). The projector will turn off automatically if no signal is detected for the set duration.
The remote control no longer works, what should I do?
Check the batteries (AAA type) and their polarity. Point the remote control at the front IR sensor of the projector (within 10 m). If the problem persists, replace the batteries. Use the control panel buttons in the meantime.
