Ok, built and love the 4.2 kit, but have been having some issues with my button on the front so I decided to build the 4.3, plus by having both i have the option of running 6 probes at 1 time. So after building and powering up the 4.3 with the Raspberry Pi 3 model B all looked well. Loaded the SD card and it started up as normal. Plugged in my TC and probes and even the fan and it looked fine except the probes where reading way low. So went into the config page to try and change the settings for the Maverick ET-72/73 probes and it would not take when I hit save and apply. I tried a few different things but still nothing. Was able to access via wifi and hardwire. So I hit reboot AVR and thats when things went wonky. Now when it powers up it starts as usual, No Pit Probe and then after a few seconds screen goes blank but lit up, all 3 LEDs are on also. Sometimes it starts up with screen dark also. I took the sd card out and reformatted and loaded the firmware again for a fresh start and same thing. Tried several different power supplies thinking it could be that but no joy(using PS i had for 4.2 also, they are PS i had laying around from camera stuff, 12v 1000ma) I ordered 2 new PS from Heatermeter page thinking maybe wonky PS) Do i need to clear Raspberry PI out, like factory reset maybe? any help would be gretty appreciated. I am an electronics guy, but not so much computer guy. Thanks again.
