Default Weird 1980s tv problem. Would like explanation.

There was an AOC tv in the mid 80s that had capacitance touch switches
on the front and the channel indicators were illuminated with NE2 neon
bulbs. An ic drove transistor switches that turned the bulbs on and
off. The sets would come in where the channel couldn't be changed.
The first one took me a few hours to repair. The soluton was to
change the NE2 bulb on the channel the set was stuck on. The faulty
bulbs still lit at the proper voltage. Anyone have an idea how the
bulb could cause this fault? At the time we were a high volume repair
service so I didn't have the time to ponder circuit anomalies. Thanks.
Chuck
