[TowerTalk] G-800s Rotator Control lamp issue

I looked through all of my Yaesu rotor manuals and there is no part number shown for the bulb, only the rating of 12v @ 100ma as you already knew.  I recall that others have taken the opportunity to replace the incandescent bulb with LED's (remember to include a diode in addition to the limiting resistor since the bulb is powered from AC).  Choosing a colored LED can add a 'Techie' look to the display!
If the bulb connects to the PC board with a connector, it might be worthwhile to cycle the connector once or twice in case it's not making reliable contact.

Hi all,

The “scale lamp” in my G-800S control (PL1 – 12v 100ma) has failed after being intermittent for a bit.  (Hitting the box no longer brings it back to light...)  It could just be a cold solder joint that finally gave way – controller is about 10 years old.

Anything I need to know before I tear into the box to fix it?  Anyone know the Digi-Key part number?
