I have an original Big Buck Hunter. It boots, but no monitor. The tube is an LG Phillips, The board was a Wei-Ya 3125B The whole assembly appears to be Makvision 3M25.
This is of course a 25" monitor.

Yes, some of the capacitors were leaking. I decided to get a universal board instead of trying to repair this one.

I got the new board in, installed it. Hooked it up the best I could with no instructions nor real prior experience ( I am a pinball guy, first video game attempt) .
When I turned it on, I saw sparking near the red lead (of the red, blue, green, yellow header) on the board. It also looks like I fried one of the heat sunk transistors. The transistor is tied into the red lead.
On the tube itself, I have a smaller red wire, black wire plug that has no place on new board along with a larger red wire red wire plug.

I know I am missing quite a bit. But I am unsure of what question to ask, let alone answer.

I guess at the end of the day, it is probable that I have a bad tube, and should just get a new tube and board assembly?
 
that replacement board probably requires an isolation transformer. That cab probably doenst have one.
 
Here are a few pics

I think gamefixer is right. Did you plug the new monitor chassis into a standard 110vac outlet or is it wired to an isolation transformer? Some of those chassis come with a standard looking 2 prong power plug that makes people thing you can just plug it into a wall outlet. If you do that you will damage it.

i just plugged it in to the at power supply. I do not think it has an isolation transformer on new chassis
 
I dont see any of the tell tale signs of NOT needing an ISO so I bet that chassis does. Also, the game board could have been damaged too. :(
 
Typically the GND trace on the monitor signal blows open. Its not a total deal killer but it does happen.

It the ground trace on the game PCB get damaged or burnt up, could you just run the ground from the monitor to the power supply?
