I would start by looking at the output of U9034, which is the 7805
regulator that drives the DR-7 displays. This is the regulator that is
connected to the four pin connector on the back edge of the little
extension at the right-front corner of the board. There are also a
couple of electrolytic caps (C9024 & 25) that are likely suspects.
These are the two vertical caps just behind the four pin connector.

Hi Folks...
Suddenly my R7A frequency display stopped working; it's
completely dark. The rest of the receiver appears to be operating
normally. Any ideas where to start looking to fix this? Thanks for
the help!
