Lightware's technical support team
is always working hard to provide the
5.4.4
fastest support possible. Our team's

can directly consult with the hardware
or software engineer who designed the
product to get the information from the
most reliable source.

However, the troubleshooting process

can be even faster... with your help.
LW3 9.6.7
There are certain pieces of information
that push us in the right direction to finding the root cause of the problem. If we receive most of this
information in the first e-mail or it is gathered at the time when you call us, then there is a pretty high chance
that we will be able to respond with the final solution right away.
This information is the following:
▪ Schematic (a pdf version is preferred, but a hand drawing is sufficient).
Serial number(s) of the device(s) (it is either printed somewhere on the box or you can query it in the
▪
Device Controller software or on the built-in website).
▪ Firmware versions of the devices (please note that there may be multiple CPUs or controllers in the
device and we need to know all of their firmware versions, a screenshot is the best option).
▪ Cable lengths and types (in our experience, it's usually the cable).
▪ Patch panels, gender changers or anything else in the signal path that can affect the transmission.
▪ Signal type (resolution, refresh rate, color space, deep color).
▪ Emulated EDID(s) (please save them as file and send them to us).
▪ Actions to take in order to re-create the problem (if we cannot reproduce the problem, it is hard for us
to find the cause).
Photo or video about the problem ('image noise' can mean many different things, it's better if we see
▪
it too).
▪ Error logs from the Device Controller software.
In the case of Event Manager issue the event file and/or backup file from the Device Controller
▪
software.
The more of the above information you can give us the better. Please send these information to the Lightware
Support Team (support@lightware.com) to speed up the troubleshooting process.
