I hear a chirping noise and the front power light flashes in sequence
to it when turning on the TV, and TV will not work. When peaking behind
TV through holes in the back, one green light (on circuit board) stays
green and another flashes to the chirping, too. this occurs at 1 second
intervals.

There is a short in the horizontal sweep circuit or in the sweep power supply circuit. The cirping tis the main power supply thats trying to start up and then it gets loaded down from the short circuit. If you have no solid state repair experience, Im afraid Im going to have to recommend that you call in a trained tech to trouble shoot this for you. Let us know what happens please and Good Luck
