at 15 great tips in regards to troubleshooting using CYP XA products when a simple power
cycle doesn't resolve the issue.
Hi there, I'm Nick Bovill - technical and training manager for CYP and today we're looking
at 15 great tips in regards to troubleshooting using CYP XA products.
Tip 1: Make sure that all firmware in regards to HDMI distribution, Source and Sink are 100%
up-to-date, you might find that one of your devices doesn't support such protocols such
as HDMI 2.0, HDR and/or HDCP 2.2 until you do.
Tip 2: Use the pattern Generator functionality of say the XA-4 or XA- 2 and input the highest
possible resolution that your system supports, and then analyse from another XA-4 in analyser
mode at the Receiver side. Make sure that you're bypassing the output resolution and
that you have copied the EDID information of the panel you're using otherwise you may
find it difficult to replicate the error.
Tip 3: Now Gradually reduce the output resolution and Timing of the XA-4 in pattern generation
mode your picture may now stabilise.
Tip 4: Swap out and test the HDMI cabling using the XA-4 Clock Error Data counting tool
and, when necessary, run a FLY cat cable when using HDBaseT and IP/Cat over HDMI devices
to try and resolve an easy issue or highlight a larger error.
Tip 5: Check your HDMI and Cat cable lengths are in range of what's being advertised by
your manufacturer and use appropriate extenders where possible.
Tip 6: Cut out any visible cable ties especially ones compromising the integrity of the cable
by over compressing it which has been the number one cause of picture intermittance
for 2016, reduce bundling and patch panels where possible, because these 3 practices
all induce electromagnetic interference within your CAT cable infrastructure.
So make sure you're cabling is conforming to HDMI and/or HDBaseT directive.
Tip 7: Change the HDMI output and/or Input of your HDMI splitter, distribution amp or
Matrices to see if the problem moves or not.
If the problem doesn't move you may be experiencing a hardware failure.
Tip 8: Change out the receiver if you're using HDBaseT, HDMI over Cat or IP and see if the
problem resolves.
Tip 9: If you're experiencing a green screen, you might be experiencing HDCP issues.
On the XA-4 setup toggle between No HDCP, HDCP 1.4 and HDCP 2.2 and see if you can replicate
the issue.
Tip 10: If your panel is behaving erratically where others in its place are working as expected,
copy the EDID of the offending panel so you can do further testing in another location
or send it to the manufacturer and change the EDID pattern of the XA-4 on the analyser
side and see if the problem resolves to confirm an EDID error.
Tip 11: If you're experiencing a pink overlay, the panel you're using may not support YUV
colour space. On the XA-4 firstly change the colour space output when working as an analyser
to RGB.
Tip 12: If the XA-4 is flashing in regards to the HDMI handshake particularly the 5v
indicator and/or simply having the XA-4 inline in front of the panel stabilises the offending
issue there might be a problem with your panel or sources HDMI port.
Tip 13: If you suspect that there is an inconsistency in regards to EDID, HDCP and/or an HDMI input
or Output and the XA-4 identifies one or all these issues, try using the XA-HDCP that provides
EDID and HDCP managment and also acts as an end sink before the panel which could economically
stabilise your sight issues.
Tip 14: If you're suffering IP lock up in regards to a presentation switch or matrices,
try removing any control system that may be causing the error and or one by one removing
any internet enabled device that is on the same network that could be potentially flooding
the system causing devices to act erratically.
Tip 15: If you have localised the issue and deem to be suffering from a HW or SW failure,
finally attempt a factory reset and if this still doesn't help, contact your distributor
and organise an RMA for the offending device.
