[Premium-Rx] WJ-8711A Front Panel Problems

[Ka9p at aol.com]

FWIW I've noticed what is probably a very similar thing going on with my  
HF1000, albeit very infrequently - flashing panel displays, random inop 
buttons.  just generally flaky behavior - and (so far anyway fingers crossed) a 
light  pressure on the front panel clears it up until the issue resurfaces a 
couple  months later.
 

I'm glad to hear the weight of opinion favoring grounding and no more  
serious morbidity issues. I'm almost anxious for it to happen again :) (not)

Michael  -

You are certainly not stupid but you may be old fashioned as you  suggested.
Many thanks to Steve for backing up my thoughts in a much more  technical
explanation than I could have offered. Several years ago, I also  had a
similar problem with intermittent front panel displays on a Racal  RA-6790. 
I
removed the four (4) front panel mounting screws and proceeded  to clean the
panel to chassis mounting points. A rotary wire brush and a  Dremel tool
corrected the problem. I cleaned the areas directly around the  panel
mounting holes on the rear of the panel and the areas on the chassis  
flanges
where the panel was mounted. A really secure fastening afterward  and the
problem was solved.  Lucky guess ?  Maybe, but it  worked.

Regards to all,
