In 1974, the Dictionary of Electronics listed mf or mfd as alternate ways to express microfarads. The use of nano fareds also came in about post 1968 or so. Before, we had 0.01 mf caps, and 0.001 mf.

Certainly check the power supply first. You likely have aging electrolytic capacitors which may be in stages of first breaking down. If the supply is also 1998 vintage, likely the electrolytics are o

Yes there are some fixes for the Scout PTO with NPO capacitors. However, first make sure the band module plugs in snugly on every contact to the edge card traces. Make sure internal grounding screws

I would suggest the battery replacement might have a problem, or some other wire was knocked partly loose and came loose all the way, when the screen failed. Can't hurt to give inside a close look wi
