[TenTec] Orion Receiver Dying

[K8JDC <K8JDC@sbcglobal.net>]

Friends,

    My Orion started acting up today.  Basically, the receiver is 
either dead at turn-on or it dies after a few minutes.  The S-meter 
freezes and the receive audio stops.  The menus and buttons still work 
fine and the display looks perfectly normal.  It's just not processing 
any RF.
    Does this sound like the power board caps?

    I have done multiple master resets, multiple RAM resets, and 
multiple software re-loads but it still doesn't want to work.  I've also 
tried a different power supply.  FWIW, I have never replaced the backup 
battery in mine either.  I'm not sure what the symptoms are of the 
battery failing.
