Crt tv,pitch!
SOURCE: High Pitch buzz noise when plugged in and it doesn't turn on
The tv has a shorted component and that is why is making the noise,call a qualified technician to find it and dont try to use it anymore.Is not a fuse.
SOURCE: High Pitched Noise
most high pitch noise comes from the anode conection on the picture tube thats connected to the flyback anode cap thats mean there is a high voltage leak,to stop the noise you can discharge the high voltage take off the cap and clean with alcohol.if the noise continue.you will have to put some red or clear silicone both the cap and tube stick together leave to dry for about 2 to 4 hrs.this will eliminate the leaking.good luck.

Hi there!
You may want to start by checking for suspicious looking components or hot spots. There may be some Caps faulty in the power supply or Horizontal. Good Luck, Jus004

There is a short circuit in the high voltage circuit. the transformer who helps to create the high voltage or his power transistor is damage. replacement needed. the repair is not expensive, because the parts are average repair. Ask for an estimate.
