Greetings to the group.

I could please use some advice on troubleshooting my BITX40.

On initial startup, the current draw looked good, but the display
illuminated for a moment with black squares, went blank, and remained
illuminated but with no intelligence - a green screen of (hopefully not)
death as it were.

Tuning affects nothing.

I injected RF at 7.1 mhz to no effect, but when I injected IF signal,
everything seemed good from there.

The red LED on the Raduino board is lit.

I've double checked the wiring. There was no smoke, at least :)

I've checked the HF spectrum and hear nothing from the Arduino/syn board.

I'm pretty familiar with basic RF troubleshooting but just beginning my
Arduino journey so no explanation would be too basic.

Any thoughts? Is it possible the sketch is corrupted and should be
reloaded, or is there a recommended procedure for checking the Arduino
output and general operability? or a simple way to reinitialize things
and see what happens? Or for that matter to check the display for
function other than backlight?

Happily my uBITX is working well.

Thanks for any ideas.
