here is my original post below, since this post i have installed a new flyback and it still does the same exact thing.
so, its not the flyback and its not the caps since they are all new and the problem still exists.
any other suggestions?


"""culprit-
ofrroad thunder with neotec 2701 monitor

problem- after game is on for a few minutes, monitor gets very bright with retrace lines and the picture is unseen because its full bright..

what i did: recapped monitor and reflowed pins.

NOW- monitor still does the same thing with brightness.

*note: if i tap cabinet top a few times, monitor will go back to normal and brightness problem goes away. but, 5 minutes later, its all bright with retrace lines again.

i swapped remotes from another working neotec and it still does the same thing.

cabinet connections (AC and color signals) to monitor are fine."""
 
i reflowed all solder joints ken. did continuity checks all over to confirm as well.
 
You may have a hairline crack in the board.

Have you also checked the picture tube on a rejuvenator for internal shorts?
