T28P with custom logo backlight issue (SOLVED)
Hi, I have a T28P with a custom logo. Every since upgrading to v72 the back-light comes on for no apparent reason. It stays on for around 18 seconds then goes off again. Unfortunately, it then comes back on approx 60 seconds later and repeats this [very] slow flashing cycle!

Is there a way to stop this happening?


Firmware Version
Hardware Version

EDIT : I'm guessing it's related to this : http://forum.yealink.com/forum/showthread.php?tid=1166

EDIT EDIT : Version doesn't have this problem.
