Ok, experts I need your help.
I have a 6100 that has vertical collapse. It was modified before I got it with "The final solution", so it doesn't have Q102 or Q103. Q705 and Q706 have additional components in line.
I have replaced the two transistors on the deflection board and all remaining frame mounted transistors.
It took a power surge and only displays the lower half of the screen, which is space duel in this case.
When I test the frame transistors with a multimeter for continuity between the case and the metal frame, I get continuity that moves back and forth between Q606 and Q706. So I am guessing the small amount of current the multimeter is providing is switching the transistors.
Where do I go next? What component is switching between the two transistors that is causing the collapse?
One more detail, is every once and awhile when I turn it on, it will work for a few minutes.
Please help!
Thanks!!
