Hey guys.
I picked up a KV32XBR200 off of Kijiji the other day for $20. With the help of my lovely girlfriend, we lugged the 175lb beast back home. Today I finally had a chance to play with it a little.
After finding the service menu I was able to get the set looking good with both 480i and 240p sources.
I don't have much experience with CRTs, but I did do some research.
I have a couple of points that hopefully you can help me with.
Thoughts?
EDIT:
I looked at my pictures, and realized that I have two big speakers on either side of the set. I have since moved them further away, but they don't appear to have had any affect.

- Is there any way to reduce the sound from the flyback transformer? I have an excellent hearing range, and coupled with genetic Tinnitus, the amount of 15-16kHz sound given off from a larger set like this one is enough to give me a headache after an hour. It generally makes the whole experience unpleasant. Some thoughts:
- Coat the transformer in something like this? Or maybe some HV Insulanting Lacquer (Corona Dope)?
- Physically damping the transformer with some sort of acoustic material? I would be concerned with both ventilation and the conductivity of the material.
- Stop the sound from escaping the back of the cabinet. An enclosure made of acoustic damping material? (Again heat would be my concern. Maybe active cooling thorough a thinner section would work?)
- I’ve had to set the picture and brightness fairly high to get the colors and image looking proper. I can hear the strain (in the 15kHz range) that this is putting on the set. I can also see the sharpness and general quality of the image edges degrade as I ramp up the picture and brightness.
- The focus towards the left and right of the screen is not nearly as good as the center. I’ve attached a picture, take note of the square brackets on each side. The bracket on the right hand side appears larger, but in person that extra size appears as blur. This is especially evident with subtitles that span the width of the screen.
