Hello,
I put together a Picocalc and after powering it up there is a vertical cascade of lines as pictured.
(moved everything from case to rule out anything interfering)
Contacted support and received a new screen. Tried that out and it does almost the same thing.
Behavior occurs whether powered by battery or USB C. The battery(s) are Nitecore NL1834 if that matters. Sometimes the intensity of the lines brighten if I leave it on for a moment but I usually turn it off quickly in case it’s just cooking.
If I blow away the PicoCalc firmware, by uploading Blink or etc to the Pico H, the backlight will turn on, but it will not display the lines, or anything (since it’s brainless after all). I’ve since re-uploaded Miny-Mite. Probably unrelated but I can connect via tty, run print “hello” and that works fine, also Pico keypresses work.
I read a lot of posts about the display being fragile and it’s possible I’m just breaking them. At first glance they do not seem to have physical damage.
But I found it odd two screens fail in nearly the same way, could there be something wrong with my board?
