GLK19264-7T-1U USB LCD remains blank

Post by daveosborne »

On a few units we've noticed that GLK19264-7T-1U USB LCDs may remain blank even though communications with the unit has been established and other controls such as brightness and contrast work. This problem is inconsistent and seems to be power up related, but has been replicated and tested with MOGD# and shown to not be a software problem.
Also a unit which has this error may be power cycled and the problem will clear, then subsequently recur. The problem has been replicated on multiple PCs, so it seems unlikely that this is due to a specific USB port or CPU.
Seeking ideas on what may cause this error.

Hi Dave,

With the troubleshooting you've done to upload new fonts and lock changes given communication has been successful this may be an issue that you may be unable to solve. As mentioned, I'd like to issue an RMA so I can take a look at that display here.

Thanks,
