started my race car after it sitting in the garage for a few weeks and the s-afc screen is'int work but the unit is still working otherwise the car wont run. if any one knows what has happend or if i can fix the screen it would be much appresated...ps; i didnt jump start it so it hasnt surged out.undefined

 

so i take it none off you have any idea?

 

i remember when this happened to my DSM. check both ground wires. if you hard wired it and didn't solder is then most likely the wire came off. good luck.

 

check the grounds.
Do the buttons light up but not the screen?
if its not the wiring, or ground then its the screen.
I had to get mine repaired.
