No picture distored sound.

As you may know, I purchased the Motorola 19CT1 color TV set a while back. I limit its run time, of course, but have found that like a car, it works best to give it limited (and supervised) exercise. Running it about a half hour once a week or two seems to maintain the best picture. If it sits too long, the color washes out on me. Actually, the very first day I got the set I was wondering if it really was a color TV or not, since all I got was black and white. Later on I'd get a weak color. On the half hour a week exercise program, I've been getting normal looking color. Of course, it can't compete with a modern TV, but it's far better than I'd expect for such an old set.

This has been a good routine until last weekend. When I turned it on, I got no picture (not even a raster), and the sound was present (could hear the audio broadcast) but it was distorted (very static sounding and muffled). It does look like the previous owner did indeed have the original capacitors replaced, so my first assumption would be one or more bad tubes (I'm sure more than one can go at the same time by coincidence).

As luck would have it, I received an original SAMs photofact document on it last night. It's a little unclear which specific tubes I should try, so I thought I'd ask for a few suggestions. Of course, it could well be a poorly soldered or defective capacitor, but since I'm not up to replacing capacitors or resistors yet, I'll leave that to the experts. Since I can replace tubes (I have a stock of all the tubes it's supposed to take on hand), I thought I should give that a try first. I work for free.



Thanks,
