You will first have to see if cp150 is puffed up on top then go from there! Also you need to resolder all pinns on FBT poor connections on alot of these sets.HAPPY NEW YEAR!
SOURCE: Replaced the Capacitors, Still have a Power Issue
Resolder all the pinns on Flyback transfomer.

The caps in these sets rarely bulge. Try checking the Horizontal Output Transistor (HOT). I suspect that it is shorted. The noise you are hearing is the power supply attempting to fire. With the defect further on, the power supply will turn itself off as a safety valve.
Keep us posted,

Hello Kira-chan,
You are going to have to take those capacitors out of the Tv and check them on a capacitance tester. Some digital multi-meters have them, but I would suggest using the LC102 by Sencore That way you can check the ESR, and the dielectric absorption of the capacitor. It is my suspicion that these caps are bad, but should be checked before replacing them.
In addition check the BLUE and RED CRTs for cracks around the neck oy the tube, BE CAREFUL.
I hope this helps,
Thank you,

If youre not getting a power light then its most likely the AC main filter board ( Where power cords plugs into ) or if you do get a power light the deflection board needs replacement.
