So I finished capping my 14" Sanyo that's kind of like an EZ over in this thread:

It seems to be the original monitor for my Warlords cocktail, and it worked fine until a couple weeks ago.
The cap replacement fixed the screen being scrambled, but now it has a new problem. When it is first turned on the image is perfect and stable, but after a few minutes of being on it starts to shake vertically. At first it's just a little vibration, but soon it's bouncing violently up and down like an earthquake.
I can adjust the v-hold and temporarily stop the shaking, but it comes back in a minute or so. Once it's on for a long time I can no longer adjust it away.
Searching this and other forums, I've seen people mention these possibilities for similar problems:
- A cold solder somewhere
- Bad sync signal from the game PCB
- Incorrect voltage at B+
- Bad V-Hold Pot
- Bad Flyback
Any other options or advice for narrowing it down? I may need to reflow everything, but the heat doesn't seem to be great for the board and I'm worried about damaging it with repeated soldering.
