The neons on the touch -tuner fluctuate, those on channels
not selected tending to light and flicker. Sometimes the set
has to be tuned in after changing channel.
The neons do sometimes give this trouble, and it’s best to
change the lot – the RS type 586-015 is suitable. Check the
value of R675 – if it’s a 12MQ type, change it to 4.7Mg. If
the troubles persist, replace the i.c. (ETTR6016Q).
