Question about Televison & Video
Whistling sound could be from power supply section that goes to protection mode when horizontal deflection section (H-out transistor, flyback etc) got shorted out.
Defective Convergence IC will blow the pico fuses of +/- supplies
Let me know model number of tv, I will check if I have its schematics to provide you more help.
