      Just wondering if anyone else has had AP4 backlight issues?

      Since Xmas alone I have had to report 5 AP4 panels with screens going faulty. Most of the time it is the screen getting large black lines then going dead. You can power cycle the board and it’ll work for about 5 to 20 mins before going blank again, Touch feature still works as you can touch the panels and see cursor move on monitor. This seems like a very big issue. If it were one or two but its been over 10 in the last few years and as I said about 5 this year alone. Firmware updated do not fix it either.

      Promethean have been very good in replacing them under warranty but this seems like an issue that should be investigated.

      Please let me know if anyone else has had this issue.
