The panel turns on and works, but after 1-2 minutes, the screen turns off and does not respond to anything. The power button does not work. I cannot turn on or off the panel, only turns off by the power switch.
Thank you for your post.
Please open the locker in the unified menu, open Settings, Display, Standby and Sleep Timers, and set this to Never. After this has been done, please test if the issue still occurs.
We look forward to hearing back from you soon.
