Ender 3 V2 print problem

[phranch]

I printed with an Ender 3 Pro for 4-5 months so still a relative newbie. Just got an Ender 3 V2 and sometimes it will print normally as soon as the bed and nozzle are at set temp, and other times it will just sit there. I have been unable to determine what makes the difference for it to begin! Any help appreciated! Edit 1-21-21: To add further details--I have a new Ender 3 V2 with a 4.2.2 board and no BL Touch.. The firmware is V1.0.2, which as far as I can tell the the most current. The problem is that when I press Print after the bed and nozzle are at temp, the lcd panel just shows "BACK". It was doing ok until a few days ago and I haven't done anything other than print, no flashing attempts or anything similar. I'm relatively new at this and the more I try the more confused and frustrated I become! Any and all ideas welcome! Oh, and I have researched and searched many forums with no luck. Edit #2--Just removed some garbage about Ginger that must have come with some copy/paste I did!! 3rd Edit--The words came back! I give up.
