Horizontal width jitter after turn on, or picture gets wide and then back and forth!
hi there, seems you're encountering horizontal width suddenly adjusted by itself.
i recommend you unscrew the back casing, clean the crt board a bit and look for the capacitor on the secondary output of the transformer voltage chopper.
it has this diode series with the output and filtered with electrolytic capacitor.
if you notice bulgy appearance replace it with same type and farrad rate. most of the times it is unnoticeable by just physical checking. Some are leaky and can be determined using capacitance tester. The supply of the Vertical IC is not stable cause by this capacitor. replacing most of the capacitor wouldn't cost you much. hope this helps, please rate and vote
Thanks,
Jeff
RCA 27r410t can't see scroll on news channels or scores on ESPN. Is there a way to adjust screen size or vertical display?
