[CVRC] Looking for some IC-R7000 wisdom.

[Scott Schappert]

Good day all:



I have recently acquired, for better or worse, an R7000.  Except that this 
radio is gravitationally challenged and will burn the casual radio petter 
without adequate airflow, it is what it is.  I noticed that when the radio 
arrived from the Ebay seller very poorly packaged, and the radio was much 
worse off than the sellerintimated.  We all get burned once or twice.



Forgive my digression.  The problem is the display control PCBA p/n B3098B 
with the NEC display driver chip, shortly after power up starts screaming 
at about 6 kHz and is terribly annoying, to the point I cant really use the 
radio.  Funny, the seller had no idea what I was talking 
about.  Re-digression, sorry.  I took the radio apart and fired it up and 
immediately found the offending PCBA.  I dont know if it is a cap at 
end-of-life, but something is dying.  I would like to replace the PCBA if 
possible, else troubleshooting to find the bad part.  So, does anyone know 
where I might acquire a new replacement board, or knows anything in regards 
to this issue, I will profusely thank you in advance for any data.



Best regards to the reflector !
