I have a JVC 32 inch TV model AV-32730 that was given to me, when I turn the set on it has a high pitch crackling buzing sound for about 30 seconds then the sound becomes normal with no noise. This only happens when the tv is turned on after it has been turned off for a while and the set is cooled down. I also noticed the sound seems to go up and down almost fading in and out when watching.
Did you find a solution because I have the same problem on my JVC?

crackling sound
Yep, I have the same problem. My TV is 32" and is 10 years old. Anybody got any ideas?
My TV will turn on for a few seconds and turn off. I can see the lamp is lit in the back. The blue switch near the lamp is in the down position as it should be. At first I heard the high pitch whirring sound when I tried to turn it on, now nothing. I unplugged the set and cleaned the dust with compressed air. From what I have been reading, it might be the color wheel. Does anyone agree?
