width problem

[radio nut]

I had another thread about my Motorola 21t16. I got some advice, fixed the problem of the picture drifting to the left and wouldn't you guess 10 minutes later my flyback burns up. Ok, It happens. I got a new one from Moyer's, reinforced the coating and waited about 2 weeks. I tried the set and now the pic is not wide enough. The width control is on the fly and is active.I checked what the sams diagram said, I also have a book by Sams and did what it said. I have subbed in tubes and it is still not wide enough, Now what do I do? By the way the fly was a direct replacement thordarson.
