Hey Folks,
New guy here. Read almost everything that has K7000 and "white raster." So I have a Zenith monitor attached to a K7000/P538 chassis in a Simpsons arcade cabinet. When I first bought it and turned on the arcade, the flyback was arcing and zapping (I almost peed in my pants) but I had a white screen - no images, Just white.
So I bought and changed out the flyback and a cap kit with no filter (thanks ian). Then I read to change out the horizontal output transistor - 2N3904 (not a chinese clone). So after all this, I powered it back on - STILL WHITE. No image or anything. I adjusted the source POT, and I get white when I turn it all the way up and black in the opposite direction. Looks like I have raster (which is good, right?)
After getting fed up with no image, I just ordered the ceramic resistor 2R7ΩJ 7 watt (i think it's R104), the cap filter, and a IC4 - STR30130 VOLTAGE REGULATOR. So if this round doesn't work, WTF do I need to do?
Forgot to mention that I HAVE NECKGLOW, and the arcade is playing blind! I put coins in the machine and hear the 'add credits sound.' I measured the RGB input to the chassis board have some current.

Put in a new cap kit, flyback, and HOT.
I have neckglow and raster.
Will replace IC4, R104, and filter cap.
About to give up.
