smart-e 4K Troubleshooting Manual

Smart-e SDS/SDX/MDX/4K
This guide is provided as a first point of reference for the diagnosis of problems encountered when
installing Smart-e products from either the SDS, SDX, MDX or 4K ranges. They follow the general
points that a Smart-e engineer would look at when trying to diagnose problems in an installation.
This document is not specific to a product from the Smart-e range, for more specific advice please
refer to the models dedicated user manual.
1. Status LEDs
On most Smart-e products are a number of status LEDs. These LEDs can indicate the status of a number
of elements of a Smart-e product. These include but are not limited to:
➢ HDBaseT link
➢ Power
➢ HDMI status
➢ Comms activity
➢ Ethernet activity
➢ HDMI data throughput
➢ Processor activity
These LEDs are designed to be a quick point of reference for at a glance diagnosis. A detailed guide as
to what each LED means is provided in a products user manual and usually include a description of what
to do if the status of the LED is not as it should be.
2. Power
The first point of failure in any modern electronics device is usually the power supply.
I. Check the status of any outward power indications be these LEDs or an LCD screen
II. If these are not lit or dim it suggests a power issue
III. Verify the operation of the power supply by swapping with a known working alternative
IV. If a new power supply has solved the issue, please contact
an image of the product serial number and they can arrange a replacement unit for you
V. If a new power supply has not cured the issue remove the power supply from the unit, remove
any other cables also such as HDMI or CATx cables
VI. Once these cables have been removed try re-attaching the power supply
VII. If the unit now powers it may suggest a problem with the cables or another unit attached,
try changing and/or verifying the cables by testing them in a known working environment
VIII. If all of these methods still do not cure the issue it is likely a fault has occurred within the
Smart-e device, please contact
serial number. Smart-e support can then begin the returns process to either get the item
repaired or replaced
