The high pitch chirping noise is coming from the power supply. there is a short circuit with the switch mode power supply. check the HOT(horizontal output transistor) first then the power supply for shorts. on the HOT check for short between base to collector, and emitter to collector. base to emitter will show short because it in line with the primary coil of the fly-back transformer.
if you are unfamiliar TV repair have a tech repair this for you.

No picture or sound - TV makes chirping noise


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

No power just a chirping noise.


Chirping means the power supply is being loaded down by a short in most cases, likely a bad convergance IC
