Hi everyone,
I am having a problem with my Wells Gardener 15V2000 monitor.
The monitor is out of an Asteroids Deluxe cocktail machine, I have verified the game board is working and displaying properly on an Asteroid Deluxe standup machine.
I have checked the voltages from the PSU to the monitor and they are correct and within range. I have also recapped both the Deflection and the HV board as well as reflowing the pin headers and most solder connections.
After I did this work, the monitor started outputting HV and I used a HV probe to adjust it to the correct voltage. When I plugged the game board into the machine and turned it on i heard defection chatter, but the monitor was not displaying an image.
After I turned up the contrast and brightness there was a haze in the right side of the screen and one of the power transistor (Q708) got very hot (burning fingers hot) and I shut it down. After buying replacement power transistors, the same one was getting hot so I decided to look over the deflection board for any burnt or broken components I might have missed, but I saw nothing out of the ordinary.
This is where I am stuck, nothing I've seen on FAQs mention this problem. I took a video of what happens to the monitor when turned on (https://drive.google.com/open?id=1FLkKyuqPh7n1PrXFCAjnJtKyEtMsLqEe).
Any help and suggestions are appreciated.
Thanks,
Jake
