   TRS-80 Model 4 video problem

   Hi All,   
      
   I'm a Tandy newbie, so apologies in advance for anything   
   obvious/wrong/silly :)   
      
   I rescued a Model 4 from the kerbside a while ago which has a video fault.   
      
   Essentially, the beam appears to be always on. Every scanline is drawn,   
   as is the retrace. There doesn't appear to be any variation in the   
   brightness, other than the retrace being a little dimmer (which makes   
   sense, I suppose).   
      
   If there are any TRS-80 hardware gurus out there who might identify it   
   as a common/known (fixable) issue for this hardware, I'd be very   
   happy... I'm not confident enough poking around near HV circutry to do   
   any live troubleshooting myself.   
      
   If anyone is keen to help, I can supply pictures.   
      
   If noone is able to help but would be interested in providing a loving   
   home for it, let me know. I'm in Western Australia though, so postage   
   may be expensive if you're somewhere else :)
