Vampire Night DLX Arcade Cabinet NIGHTMARE

Hi everyone I have heard and read a lot of awesome stuff about this website also it is the home for a load of very talented people and I was hoping maybe someone could help me solve this nightmare I am having with a certain arcade cabinet if that's OK with you folks?

Anyways I have a Vampire Night Deluxe which I am trying to get up and running. Firstly the huge 46" rear projection screen decided to spark from the flyback and not work but thankfully I found a replacement screen which went in nicely. But now the bloodly game board is giving me grief and I was wondering if anyone else has had fun tinkering with a Namco System 246 before because I have read online that they can be a nightmare so I am expecting a bumpy road ahead. Anyways the issue I have is the machine powers up but the game board seems to display a message:

JVS CONNECTING...
[ Jv Monitor]

Once it get's to this message it seems to just hang and I have left it for a couple minutes just in case but normally it would of booted by the same time frame. I did even plug in a small TV just make sure it wasn't the screen or the cable or something but it displays the same message.

I have also stripped it down and cleaned the system but it doesn't seem to make a difference, also now it will randomly not display any errors just a blank screen. I'm at my whits end with this damn board it seems no matter what I do it just keeps giving me the middle finger.

Here is a image link of the JVS board:

Here is a photo of my version of the Namco System 246:



Serial Number:



I checked the voltages at the power cable for the JVS board and I got the following:

Red 5.27V
Yellow 12.57V

I took all the connections off and reseated them but still no joy I am about ready to take a chainsaw to this cabinet.

Here is a video of the Namco JVS I/O board in action (sorry about the shaky hands)

If anyone could help or offer some advice that would be greatly appreciated and I may even be able to sort out a free ticket to the arcade I am working at for whoever helps me get this running as an extra thank you (UK only).

Many thanks folks

 

Did this cabinet work before you had the screen burn out on you? Speaking of the screen what exactly happened? You mentioned that it sparked meaning something caused a short or you had voltage spike which might have burned something else besides the screen. I would look at the capacitors as a possible fault and look to see if anything looks burned or in case of the capacitors leakage and or bulging.

 

The cabinet worked fine before the screen died on us, it was completely playable and worked great. The reason the screen died was because the flyback transformer died or was leaking high voltage, it's quite scary turning on the machine to hear loud crackling and to see blue sparks emitting from the flyback transformer. The weird thing is that when we installed the new screen which came from a exact same cabinet it tested out OK and displayed a picture and was playable but after being turned off for a few days it then just decided to do the JVS Error when turned back on, very frustrating.

 

The transformer might have burned some chips on there, not sure where to start checking though.

 

Maybe the problem is not the board, you should try with another I/O or JVS board just to check.

 

Hopefully you are using another transformer or the same thing will likely happen.

 

@Kaicer - I wish it was that easy but I can't seem to find an exact board anywhere online.
@Helder - It still is using the original power supply for the whole unit. The screen is not directly connected to the power supply but it is simply via USA style mains plug and then a vga to scart lead for the video picture. Also the problem with the screen was that the flyback transformer plastic had broken down and high voltage was escaping we have seen this before on a few other cabinets that that just needed a new flyback and a whole cap kit installed. The next port of call was I was going to check the voltage from the psu to the motherboard.

This machine is a bloody nightmare lol
