Question 1

My ACER H9500BD projector is tripping the circuit breaker, how can I resolve this issue?

Accepted Answer

A tripped circuit breaker generally indicates an overload or an electrical fault. The ACER H9500BD consumes a maximum of 445 W. Here are the checks to perform:

Electrical Circuit Overload

Is your wall outlet on a dedicated circuit or shared with other high-power devices (air conditioner, heater, another projector)? Try plugging the projector alone into another outlet to eliminate an overload.

Check the Power Cord

Inspect the power cable (plug side): look for signs of wear, scratches, wet spots, or damaged insulation. A faulty cable can cause a short circuit. If the cable is damaged, it must be replaced.

Clean the Dust Filter

A clogged filter blocks ventilation and forces the projector to overheat. The thermal protection activates and may trigger an abnormal power cut. According to the manual, the filter should be cleaned every 1000 hours. After cleaning, activate the High Altitude mode to optimize ventilation.

Check the Temperature Indicator

Observe the LED (indicator) Temperature of the device: if it blinks rapidly, this indicates a fan failure. A ventilation failure causes overheating and risks a power cut. The fan should be inspected or replaced.

If the Problem Persists

If the circuit breaker trips upon startup or after a few seconds, this suggests a serious internal fault (damaged capacitor, failing insulation inside the device). The projector will require professional repair. We recommend contacting an authorized ACER technician.

Question 2

How do I adjust the colors of my ACER H5360BD projector to correct a purple or green tint?

Accepted Answer

Your ACER H5360BD projector has several tools to correct color tints. Here’s how to proceed:

Solution 1: Change the Display Mode

Access the Color menu and test the different available display modes: Bright, Standard, Film, CinemaASF, Games, or Sports. The CinemaASF mode is generally optimized to provide color reproduction closer to a standard TV, with fewer extreme hues.

Solution 2: Adjust the Color Temperature

In the Color menu, set the Color Temperature: a higher value will make the image cooler (reducing red and amplifying blue/green), while a lower value will make it warmer (amplifying red). If your characters lean towards purple/green, try gradually reducing this value.

Solution 3: Adjust RGB Channels Individually

For fine control, use the Color > RGB Channels menu to adjust Red, Green, and Blue independently. If you have a green or purple tint:

Green tint: reduce the Green channel
Purple tint: reduce the Blue channel and/or increase the Red

Solution 4: Correction via Wall Color

The Wall Color menu allows you to correct based on your projection surface. If you are using a standard white wall, ensure that the setting matches. A poor selection can introduce unexpected color tints.

Tip: Start with the CinemaASF mode, then refine with the Color Temperature. If the problem persists, use the RGB Channels for ultra-precise adjustment.

Question 3

How far from the ceiling should the Acer H6518STi be positioned for a 120-inch projection?

Accepted Answer

The Acer H6518STi is a short-throw projector with a projection ratio of 0.5:1. This means that the projection distance is very short compared to the screen size.

For a 120-inch screen, you need to position the device approximately 1.3 to 1.4 meters from the ceiling to the projection screen.

Some useful references:

At 0.9 m: 80-inch screen
At 1.1 m: 100-inch screen
At 1.3-1.4 m: 120-inch screen

These distances should be slightly adjusted according to your specific setup and the projection angle. For more accuracy, refer to the complete projection distance table provided in the product's technical documentation.

Question 4

How to remove and clean the air filter of the H6502BD?

Accepted Answer

The H6502BD projector has an air filter that requires regular maintenance to maintain thermal performance.

Removal and cleaning procedure:

Step 1: Turn off the projector and unplug it from the power supply.
Step 2: Remove the air filter from its location (it usually comes off without specific tools).
Step 3: Gently clean the filter with a vacuum cleaner or a soft cloth. Avoid damaging the filtering element.
Step 4: Reinstall the filter in its original position until it locks in place.

Important: If the filter or ventilation openings become clogged with dust or dirt, the internal temperature of the projector may rise and cause damage. Regular maintenance prevents these issues. Also, ensure at least 50 cm of clearance around the projector to guarantee adequate airflow.
