Jeff, I am not trying to argue with you but this set doesn't have any
convergence chips. I have replaced the regulator, horz output and 4.7 ohm
resistor off pin 2 of the regulator. I have also checked or replaced all
the parts listed in your first post. Sorry for not stating that clearly in
my first post my bad, but no matter what I do the regulator is the problem.
I need an original from either Emerson or from an Emerson chassis tv. I also
tried on of the original regulators (STR30110) I ordered from Fox
Int.(Emerson) which they said was made by Orion, in the other tv that works
fine and the new regulator doesn't work in that tv either. There is no
control voltage on pin 5 (7 volts) but the original regulator that was in
the tv works fine in both tv's.
