DMM7510 print(display.lightstate) always returns display.STATE_LCD_OFF after power-up

print(display.lightstate) always returns display.STATE_LCD_OFF after power-up

At the same time, the device screen is turned on.
This variable starts to work normally only after writing any value to it.
Perhaps the variable does not have an initial initialization.

Hi, 
The default value should be display.STATE_LCD_50. What firmware version are you running on? This does not appear to be the case on firmware version 1.7.12b.

Hi :)
Thank you!
I have to check it out. In the list of fixes, this was not announced and I did not update the firmware.

Hello!  I checked version 12... the problem remained.  It still hasn't been fixed.
