VFD2041 fried?
Posted: Fri Jan 08, 2010 5:06 pm
Hello,
I recently dusted of my VFD2041, which is probably one of the first revisions (about 10 years old). I've done some development for the display and it has worked OK for about 2 weeks. Upon installing in its intended location, I noticed it no longer displaying the flashing cursor when power is applied. I took particularly care making sure it received exactly 5 volts. I fried a different VFD2041 years before because of incorrect voltage and it also stopped displaying a flashing cursor.
My question is: when power is applied to the VFD2041, is it always supposed to show a flashing cursor? Could my VFD2041 need some kind of reset, or is it fried somehow?
Thanks,
Marty
