Chirping is almost always caused by the HOT transistor and Flyback transformer. You can get the Flyback with HOT repair kit for your model from www.tvrepairworld.com they are listed under the RCA Repair kits.
hello it sound like 1 of the capacitors may blown or swelled up. with the power of you need to do a visual check of the board inside check for any burn't part i'e resistor capacitors transitors diodes any more info you need get back to me
Chirping sound is coming from coil on right side behind FBT, resolder then use Glue gun to glue on top of coil LL037,Make sure high voltage wire from FBT to Trippler is in Good this is what maybe causeing lines and fuzzy picture.Also make sure solder on all pinns of FBT are good.
The chirping sound is the power supply coming up then breaking down because there is a short somwhere in the high voltage. The most common fail in this area is the horizontal output is shorted ( 237470 ) but what cause this short could be simple cold solder joints or the High voltage transformer ( 239111 ) If you have noway to "ring" the flyback change both parts
