36" RCA T.V.

[Dani]

T.V. works fine, but has minor noise in pix. It takes time for it to
show
up, but gets no worse, & comes & goes. You have to look close to see
it! Looks like noise in the horizontal, throughout the whole pix, the
words
on info channels quiver, ever so slightly. No bad connections in the
horizontal
drive/output area, @ the flyback, or in the PWM power supply. I can't
see it
on my scope. It's an ATC113CA1. Anyone see this? Dani.

Dani,

I saw like this twice and it was the G2 or focus pot arcing on bad
spot. Scope the G2 with volts/div low enough to see the noise or
spikes, or vibrates, you got it.

Also just in case, replace CRT socket or the G2 blue or yellow disc
cap but this only make this overall brightness flicker. My eye is
sensitive to that kind. Other techs/boss don't notice.

The fix was new fly.
