no values for top left display items

Post by PETE »

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..

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