[Solved] LCD Cycling Between Blue and Off on First Start
Hello! We have just finished our first build and unfortunately, upon first turning the printer on, the LCD just cycles between blue and off. There is no text. After a few cycles we have turned it off and unpluged. Any ideas? Thank you!
When you say off, do you mean completely off as in no power.
My new Mk3S+ power cable is a bit loose into the socket at the back of the PSU. Any slight movement of cable, and it disconnects the power. Check to see if your power cable is a tight fit.
Thank you very much, reb! My problem turned out to be different, yet very similar - lose wiring. One of the LCD wires came lose on the Einsy board, which resulted in the LCD cycling between blue and blank. It did not really lose power, just did not display anything. Happy New Year!
