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.
