   You might try a manual 'reset to factory', or a USB   
   re-flash. These procedures don't need an active screen   
   or remote.   
      
   I've yet to run across an audio-ok/blackscreen situation,   
   so can't advise.   
      
   You can take off the back and hunt for obvious problems   
    like bulging caps or iffy connectors.   
      
   To troubleshoot, you'll really need to get a service manual.   
   This should tell you how to get the back off, without   
   bending something. It will also offer test points for   
   measurement.
