That usually means a problem in the start up or deflection circuits. Diode, Horizontal ouput or driver transformer. What Chassis is this set, and I will be ableto give you some better information. Rca , GE and phillips need to be diagnosedwith the chassis number. Let me know the chassis.
Your problem is a shorted horizontal output transistor C5148 located behind the highvoltage transformer on a heat sink with a clip over it and you can't see the number unless you remove the clip Has to be unsolded and solder in new. Also the highvoltage transformer must be replaced This is the big part with the large red wire coming out and going to the top of the picture tube. Must be unsoldered and replaced with original RCA .....do not get a replacement It has several connections plus three wires to connect to it and I recommend using desoldering brad can get at Radio Shack 5 foot roll. Well as you can see it gets pretty involved. You can't get the parts from most distributors unless you have a business. If he tackles it and has a distributor the parts would run about $50 to $60 and a repairman average should be less than $200 and more than $150 hope this helps. Contact me for any questions you may have. I am more than willing to help.
Chirping means the power supply is being loaded down by a short in most cases, likely a bad convergance IC http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html
