I recapped this monitor and it was so dim the light guns would hardly work. Did the flyback, still dim but now it was narrow.. It wasn't narrow before the flyback but it might be coincidence? A friend rejuved the tube today (thanks again Jeff) and it looks amazing other than this issue. This is how it looks with the width coil adjusted all the way out.

Other information, it's in an Area 51/Max Force combo and it had that big block thing on the old flyback. I'm thinking of swapping the flyback again and see if the issue goes away.. The flyback wasn't failed, I changed it to try and get rid of the dimness and it changed nothing. B+ is spot on.. It has a remote board and I can adjust it back and forth fine. I've read about swapping things out to make the picture wider or more narrow but why would this change with the flyback?

I'm at a loss and would appreciate any comments.

Thanks!

I don't think the flyback would make much of a difference but the cap kit could.


However, you mentioned that the original flyback had the other block, I think this block was used for increasing the intensity of the display, this could have the added effect of pulling the picture wider.
 
You're not only testing with Area51 right? That game is designed to have black bars on the sides. Especially in a 7000 where you can't adjust the width.. Try another game. Your monitor is probably fine =)

just curious what is the value listed on your C38.

as suggested i would try another game and see if it still has the width issues.

and out of curiosity is your linearity coil (L2) still glued down or is it broke loose.

Yeah my Area51 has black bars on the sides when I throw it in my Turtles cab with a K7131. I just tested it in one of the Mortal Kombat cabs with a 7400 in it and it still has those bars. Both TMNT and Mortal Kombat are full screen.

I'm not there now so can't check. And it was glued down before I broke it loose.
 
be sure to glue it back down for proper image display.

if you can i would like to know the value of the cap.
it could be a little bit of a different value who knows.

that cannot be the value of C38

C38 is a poly cap and that is an electrolytic cap that would have blown it top on power up.
