Hi - my Aqua Trol LCD is not showing all of the digits that it is supposed to. I have worked my way through the trouble shooting manual to test voltages and resistivities and everything seems OK. The one part that I am not sure about is the last voltage test - am I testing the DC voltage between pin 2 and 4? If so then that also checks out fine.
Do I need to replace the DSP board? Or does the LCD portion need replacing?
