Neo-Geo Monitor Problems - Please Help!

[TigerSaw]

Okay, I have an original arcade monitor that wont turn on. It's wired properly though an isolation transformer. I realized the fuse in it was blown, so I bought new fuses but the best i could get were automotive fuses. I ran AC from the wall through Iso. Trans. and to the monitor, after immediately blowing 3 automotive fuses back to back, I ordered some proper fuses from my local arcade store. I popped the new fuse in, plugged it in, and instead of the fuse blowing, the monitor made a Dr. Frankenstein type electric noise, there was a bit of light, and smoke and i quickly pulled the plug. Now when I plug it in, it doesn't even do that much ....

Where do I start with fixing this? What should I look for? Any ideas? I can give model numbers, pictures, what ever you need, please help.

You are going to get much better help here than I can give you, but I would check the transistors on the side of the chassis first.

They look like little metal cans with the part number stamped on the top. They'll have a few pins sticking through the metal with wires attached.

There is info on how to test them, but honestly, I don't remember where I saw it.

ed12 and a few others will be here shortly to get you up and running.

Thanks for the fast, and very nice reply! I do hope someone shows up to help! ... in the mean time, I have more information to provide.

1. It's a Zenith GA63ADG25X 04RC0105-005 tube. - 25 Inches
2. It's a Wells-Gardener Model 25K7193 Chassis
3. I have taken it apart and found what I think to be the main problem. Pictures posted... there was a burnt area, under what im calling the magic monitor beans .... I assume they're capacitors of sorts. The larger of the 2 was cracked. Once removed, I found a hole in my chassis board.

From the photos you can see the damage isnt THAT bad, Im wondering if there is a fix for this IE Soldering small wires from the areas needed to the path on the board.

Any ideas or help would be greatly appreciated.

that is repairable,clean the circuit board and replace the cap-use wire to remake the burnt out track
all this was caused by a bad solder joint

any way you could edit the picture to show me what you mean?

and are we sure it's a solder joint? the larger of the 2 "bean" capacitors was split wide open. I think that's what caused the problem .... I THINK ... or it might be something somewhere else .... but I mean you tell me.... Im not expert at all here.

yeah the solder joint killed the cap and then cap probably caught fire
polypropylene capacitor you mean

i would consider myself as quite experienced as i have been repairing coin op equipment since 1986

so this is 100% repairable? know of any place/site that shows how?

thanks for your replies by the way, giving me hope = )
