Have finally managed to repair my Kenwood TS930S Transceiver, got hold of another TS930 last January which had an intermittent plasma display, which eventually failed as well, so decided I was going to think this one out, decided that by swaping the plasma displays, I could decide if it was a defective display, it showed the displays had similar symptoms, both not working, so then decided there was nothing to loose and went to the micro processor board which has 4 to 5 dual-in-line connectors on each edge of the board.

 This is the fifth and final part. Enjoy! Leave a comment below...
