13" GO7-FBO in Centipede Cocktail shrunken 1" (horiz. issue)
Friend gave me a Centipede cocktail that was playing blind about 6 months ago. I checked the monitor and it had a few vented caps in the power supply... 5 mins later - $1 for a Centipede cocktail!
Then a week or so ago, I left the machine on overnight. I woke up and there was a burning smell coming from the machine. The flyback had cracked and leaked ooze. The horizontal output transistor was also checking shorted, and the 1.0a fuse next to the large cap.
I ordered a new flyback from twistedquarter's ebay store, found a NTE cross for the HOT (D871), and got a 4a fuse. Installed all of these, and the pic came up, but shrunken about an inch on all sides.
After verifying the jumpers are in the correct place to adjust vertical and horizontal, I used the pots on the back to adjust the vertical (in game = left and right sides due to vertical orientation of screen in cabinet) and this comes out ok. However, adjusting the horizontal width coil (with the proper tool), barely increases the width (top and bottom of game due to orientation). I checked the connections on the flyback and the width coil and went over them to be sure. Also checked for 120B+ this is OK as well. Pic is still shrunk. So here's my question(s):
(1) Checking the listing for the flyback, it says it was for a 19" G07, and I have a 13". Will this matter? The website lists only one for G07 monitors, so I wouldn't think so, but now I am having a problem.
(2) Could the D871 cause the problem? NTE says it crosses and replaces the 2SD870, but again, I am now having a problem.
(3) Do I need to install a cap kit? I've already replaced a handful of caps, and I believe it was likely recapped before, as many of the caps do not *look* old. I had no vert/horiz problem before, so I am not really thinking this is the cause, as they appeared to be fine before replacing the flyback.
(4) Should I be replacing C515 with a different cap to increase the width? I've heard this has helped people before.
Any help greatly appreciated!
