Good to hear yours is behaving better. Mine went downhill over a protracted period. Moving the brightness from auto to manual and turning it down 50% as others have suggested kept it going for several months though difficult to see in bright sunlight. Like you I initially found that powering it down and up again would get it back on but eventually it was a complete fail. DTronix said parts are getting hard to come by now but they were able to repair the circuit board in mine and it’s back to full bright working order. My understanding is the screens are akin to a computer monitor (i.e. they are plug and play rather than running own software). Regards
