Good afternoon,
I think I may have fried my JackAl PCB.
-Connected only programmed Teensy 3.6,? 5" touchscreen and 12 volt DC supply
-JackAl screen came up and all looked good
-Then after about 60s the screen went blank and LED on Teensy came on and stayed on
-Power cycling made no difference
-Reprogrammed Teensy 3.6 with BLINK program and LED blinks as expected so I suspect Teensy is OK.? Reprogrammed with JackAl
-I have no idea how to troubleshoot the display
-I went over everything and eventually found a HUGE MISTAKE on my part.? Instead of 7805 I had installed 7812 for U2.
-I remvoed U2 and installed correct 7805 but I think at this point the damage was already done for symptoms did not change
Short of buying another JackAl PCB does anyone have any suggestions or can anyone repair the JackAl PCB?
Much thanks,
Vince? N1VIN
