Issue 1: Screen Is Not Clear / Blurry

Checks:

• Press the Focus button on the remote and adjust until the image sharpens
• Maintain a projection distance of 1.2m–4m (recommended 4–10 feet for best clarity)
• Use the projector in a dark or low-light room
• Ensure the projector is placed straight and level relative to the screen
• Go to Settings > Projection Settings > Auto Keystone Correction and enable it, or fine-tune with Manual Keystone

Issue 2: Projector Not Powering ON

Checks:

• Check the power cable and adapter connection at both ends
• Ensure the power socket/outlet is working
• Look for any indicator light on the projector confirming it's receiving power
• Try a different power outlet or cable if available

Issue 3: Projector Turns OFF Automatically

Checks:

• Check if Scheduled Power Off is enabled under Settings > Other Settings and disable it if unintended
• Ensure ventilation holes are not blocked — overheating can trigger auto shutoff
• Let the device cool down in a ventilated area before powering back on
• Confirm the power connection is stable and not loose

Issue 4: No Display / Black Screen on Projector

Checks:

• Confirm the correct input/signal source is selected
• Restart the projector
• Reconnect any HDMI/AV cable securely
• Ensure the lens cover (if any) has been removed

Issue 5: Screen Is Tilted or Distorted

Checks:

• Go to Settings > Projection Settings > Auto Four Keystone Correction and enable it
• Or use Manual Keystone correction to adjust the image shape
• Ensure the projector is placed on a flat, level surface, facing the screen straight-on

Issue 6: Wi-Fi Not Connecting

Checks:

• Restart both the projector and your Wi-Fi router
• Go to Settings > Network Settings, re-select your network, and re-enter the correct password
• Move the projector closer to the router for a stronger signal

Issue 7: Bluetooth Not Connecting

Checks:

• Restart both the projector and the Bluetooth device
• Go to Settings > Bluetooth > Bluetooth Settings, remove the paired device, and re-search/re-pair
• Keep both devices within close range during pairing

Issue 8: Screen Mirroring Not Working

Checks:

• Ensure both the projector and your phone are connected to the same Wi-Fi network
• Restart both devices
• Use the Transcreen app (Android) or AirPlay/Screen Mirroring (iOS) as described in the manual
• For laptops, use a wired HDMI connection instead

Issue 9: Apps Not Working / Crashing

Checks:

• Update the app from the built-in app store
• Restart the projector
• If the issue started after a system update, restore factory settings via Settings > Other Settings

Issue 10: Projector Stuck on Logo Screen

Checks:

• Please raise a support request.

Issue 11: No Sound / Low Volume

Checks:

• Increase volume using the remote's Volume +/- buttons
• Check that Mute isn't enabled
• If using Bluetooth audio, check the connection and reconnect the external speaker

Issue 12: File Manager / USB Drive Not Detected

Checks:

• Reinsert the USB drive
• Try a different USB port or a different USB drive
• Ensure the drive is formatted in a supported file system (e.g., FAT32)

Issue 13: Device Feels Warm During Use

Checks:

• This is expected during normal/extended operation
• Ensure ventilation holes are not blocked and the projector is in an open, well-ventilated space
• Turn off and let it cool down if it feels excessively hot

Issue 14: Can't Install Apps via APK / Sideloading

This is expected behavior — sideloaded APKs are not supported. Use only the built-in app store for installing apps.

Issue 15: OTT App Not Mirroring Properly

Some streaming apps restrict screen mirroring due to DRM/content protection policies. Use the app's built-in playback on the projector directly, or connect via HDMI instead of mirroring.
