Weird problem, set is a Mitsubishi 50CK03 (I think), ca. 1992. Very nice
set, but when it came in it would not lock onto any channels. After
replacing the bad prescaler IC and a few caps, it seemed to work fine. Then
I noticed that when it was first turned on, the picture was snowy, and after
about 40-60 seconds, it suddenly went perfectly clear. It does this every
time it's turned on. I checked just about every cap in the set and couldn't
find any more bad ones, so as you can guess I'm running out of patience. The
only thing I haven't replaced is the tuner (too expensive!).
However, I recently got an identical set with a bad CRT, so I plan to swap
the tuners and see if that makes any difference. But I figure it couldn't
hurt to get some advice in the meantime......
Thanks for your help.
