I picked up a Defender project. I rebuilt the power supply and got it running with voltages right on the money. I then moved onto the monitor, a WG K4600 and found it to have vertical collapse. It had some cracked solder joints on the XY daughterboard so I reflowed all connector pins, did a cap kit and I found no change. I then replaced the two vertical transistors (I never actually tested them) and found that I had an image that wasn't fully collapsed but still not quite there (pictures attached)
So anyway, I was hoping someone could lead me into the right direction to get this problem solved.
I'm also attaching an image of the neck board. I found some ceramic caps that have been removed or broken off. They were clearly soldered on the board at one time and the legs are still. I don't know if it was done when it was new or clipped off later for some reason. I mean it seems obvious that they have broken off but it's just odd that two of them aren't bent. they are C408, C409 and C410.
Maybe someone can tell me if these caps are present on their neck board.
Thanks guys!
