Hi there. new to the forum but have been using HM for probably 8 yrs... running a 4.1. I am working on building a new 4.3 and have completed all the steps but am getting some odd behaviors. Note that it is not yet hooked up to a RPi
1.) When powering on, sometimes i'll get blower activity but it starts and fades. when pressing on the ATMEGA chip, sometimes it'll kick back on and sometimes not.
2.) I get absolutely no voltage reading on LE1 when it should be reading 3.3V at least according to the schematic on the wiki.
3.) when connecting the LCD, it will sometimes power up and sometimes not. If it does power up, it'll be a backlit display but no text is visible. Then it loses power and cuts off entirely.
I have checked all solder points and everything, at least to my eyes, looks fine. I'd love any thoughts on what specifically to check. happy to attach photos of the boards if it'll help.
Thank you and please help!!
