14. Trouble Shooting

14.1. Front Panel LED indicators

➢

User should see Input / Output LED lights in each channel. If no light illuminated in specific

channel, please check Input / Output connecting cables, signal source & projector in that

channel.

➢

If user sees continuous flashing (0.5 second interval) in some channel LED, it means OSD may

be locked. Please press [Menu] key for 5 seconds or press 850 number keys in remote controller

to disable [OSD locked].

➢

If user sees flashing LED on Input/Output LED indicators at the same time with 1 second interval,

it means the system gets wrong FW/MCU code or HW failure. User can turn off/on the system

again to see if it can solve the issue or not. User can also update the MCU code and FW through

GUU PC tool. If the issue is still existing, then user needs to apply RMA and send back the unit to

factory for checking.

14.2. No image in the projector

➢

If UD100 output resolution is set at 4k and projector can’t support 4k input, user will see no

display image in the projector or display device.

➢

Please use remote controller or front panel output selection keys to select [1080p] output to let

display device to support it.

➢

user still can’t see the image, please click [Menu] key to activate OSD. If user can see normal

OSD, the system should be normal. Please click [INFO] key to check input and output timings.

➢

If user still can’t see the image, please change signal source, HDMI cable or display device to

find the root cause of the failure.

➢

HDCP may be the reason for no image. Please make sure projector is HDCP compliant.

14.3. Intermittent or Loss of Input Signal

➢

Check the HDMI cable quality and make sure all cables are fitted correctly. 4k/60 signal requires

high speed certified cables.

➢

Cable length: Connecting cable length should be as short as possible. Replace a short cable to

verify the possible root cause.

➢

HDCP compliant issues: If the input source or the monitors are not HDCP compliant, it is possible

to stop UD100 from negotiating HDCP link and show intermittent, abnormal or no image. Please

check HDCP condition in signal source or display device.
