After assembling a K8098 kit, purchased from Jameco on 9/8/20, I found no video, only backlight on LCD. Viewed signals @ SK1 pins and found pulses, but also half-level logic signals on other pins. These pulses did not change when SW1, the mode switch, was pressed. Suspected that IC2 was defective, however wanted to confirm. Had previously purchased and assembled a K8098 kit on 9/9/19 and it performed perfectly, so removed that IC2 and exchanged it with the suspected unit in the current kit. Found that this corrected the condition. Could you please send me a replacement IC2 (VKVPA20 programmed with DSPIC33FJ321/SP)?
Since this concerns a technical defect either CPU.

Okay will attempt the route you suggest, however I do find it difficult to believe that you cannot simply send a replacement IC. I’ve viewed the comments/complaints that have been sent to you regarding this unit and suspect that this is a quality problem that occurs during one of the steps in the manufacture of the components for the kit. Thanks for your time.
