Been enjoying the Dumont. The set has logged close to 40 hours since I've had it. Still can't get the brightness down. What you see in all the pictures is with the brightness at minimum. Linearity is off on the right side of the screen and I can't get to the control without removing the chassis. Once I order some power resistors I'll pull the chassis again. The set weighs near 90 pounds so its not easy to move around.

Here is the first picture I got on the screen almost two months ago

The set worked great with no interference on the screen when I had it upstairs under repair. After lugging it downstairs with my wife's help I get constant interference. Not as bad now with the DVD player connected but still pretty noticeable. I think its coming from inside the set as I've shut everything off I can think of downstairs including our Wifi and it the set still shows interference....

Some current photos.

Thanks!
