Thanks for the ideas Finn! That is one fancy display.I think you could replace it with an 20x4 LCD display. Suspect it would be a direct drop-in with the 15 pin connector. Yes, you'd have to figure out the backlight (A and K pins) and maybe contrast.But first check for +5V (you could do that with the display unplugged and plugged in).If the 5V regulator is bad or +5V is shorted to ground then anything else is pointless.Next thing I would try is re-seat the CPU chip.FinnOn 7/31/2024 10:55 AM, DOUGLAS LOMHEIM dlomheim@aol.com wrote:Group:Could corrosion like this be indicative of a poor solder joint?
