I have a general question regarding horizontal frequency in a TV. I
have this set that tries to power up but shuts back down. Anyhow, I am
going to scope the H drive pulse and such, but if the frequency isn't
what it should be (suppose to be around 15.7Khz?), would this likely
be part of a protection circuit shut down in some models? Would the
same be true for Vertical as well? The screen and heater voltage is
swinging also. I am trying to repair this with as little help as
possible. This is why I'm not going into details on model #, make, and
such. Thankyou group.
