I have a problem with the Oled-display of power box mercury.
When the power box is switched on, the screen is turned on upside down. If I turn off the powerbox and returned on immediately the screen is not stable, it flashes. The only solution is to unplug it and reconnect it. When I do this manipulation, the screen will display correctly the location until the next cycle. The powerbox seems to work all well.
It’s not easy to explain the problem in writing and I don’t speak English very well, sorry.
Thanks for your help.
