[Kenwood] TH-79A Display Faded Out

[Stephen Clark]

My TH-79A display has faded to the point where no characters are visible.

This also happened a few years ago. I opened the radio to fix another problem 
and had to disconnect a ribbon cable that I think goes to the display.  After 
that the display worked better for a long time.  However, the problem returned 
gradually.  I have opened the case twice to mess with the ribbon cable again.  I 
tried to clean the cable with an eraser once, and cleaned the cable with DeOxit 
a second time.  Neither effort showed any improvement.

Can anyone help me?  The TH-79A is a nice radio except for the display.
