Well friend chirps come from the primary side of the power supply normally you may have had a serge of some kind and it blew the power supply. or chirps also come from the inverter board, this when coils short out.
This is not a Convergence Problem.
The unit is worth Fixing as Either board would cost you around $150.
with your problem check the 24v line make sure power supply is supplying the inverter if it is rule out inverter then listen to pin point the noise. i would use cold spray on the components to find the problem.
Now you would ask COLD SPRAY?
I would explain you.
well you may not need it if you open the set and listen to the chirp. But if you can't pinpoint it the spray changes the temperature to the failing part and once the spray hits it, it should alter the chirp. you should not have any problems because you can here your problem, it's either your power supply board or inverter. just open set listen and pinpoint problem that's, simple well.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
