Hi! I have completed construction of the DSO 138. After locating a few bad solders,
I have it working real fine. Only 1 issue remains. I am unable to get any values to
appear for Freq, cycl, pwr and duty. Is this a problem with the LCD Module? Which
connector pins are used to input that information to the LCD module. Appreciate
any assistance..

I have the same problem. Does anyone know why?

have you tried making sure the timebase is selected then holding down on the OK button for about two seconds?
