I encountered that problem a year or two ago -- the bulbs in my Yaesu 
controller burned out after only about six months, clearly a design 
failure.  It looked to be quite difficult to replace them, and also to 
find replacements, so I improvised the installation of a couple of white 
LEDs alongside the right side of the display, poked around the schematic 
to find V+, and connected the LEDs to V+ through suitable dropping 
resistors to limit the current.  Two years later, they're working fine.  
although the original bulbs illuminated the face more uniformly.
