I have a Sony 31" trinitron that was made in June of 1996. My family had it since new and gave it to me. The problem is, the picture is in black & white. It does this on all inputs and through the antenna/cable connection. What's interesting is, the on screen graphics are still in color while this is happening. That leads me back to something in the input stage and the color circuits are ok. Also, sometimes it will work fine for the first 5 or ten minutes of operation, then it goes black & white. I was thinking maybe there is some cold/bad solder connections on the board somewhere. This is a very heavy set (as you probably know), so that has prevented me from taken it to a service tech. I have audio repair skills, but have limited television knowledge. I know the proper HV procedures for servicing, and have done repairs before, but I don't know where to start on this somewhat new set. I may not even mess with it since you can get CRT type sets for nothing or near nothing now that people are upgrading to Hi-def. I just want some suggestions in case I decide to tear into it. It was an expensive set when new (weren't they all?
), and it does have a beautiful picture when it is working correctly. I would just like to save it and put it to good use. Thanks for any help, John.
