#18 Kenwood TS 940 DOT on display Chasing down the rabbit hole Pt 1

In this video I have a TS-940 that has the dreaded dots on the display. After doing the regular checks for signals and voltages on the PLL's I decided to start looking for other issues that can cause this problem. So which is causing this problem? Bad wire connectors, cracked solder joints plus PLL unlocked.
