PC - Jpac - JAMMA cab problems!
(1/2) > >>
keyamon:
i've been trying to help my mate sort out his JAMMA cab which has a jpac and pc in it with an Arcade VGA card.. i thought is was maybe a software/drivers problem, but we're reinstalled stuff and it's still the same.
the problems are:-

1. the screen will never stop rolling (can sometimes get it to go real slow)
2. you have to press F1 for the PC to load windows!? or it just hangs with a blue flickering line.
3. i put in a ATI Rage Pro to try and run the PC on a normal monitor so we could see what the error message was but the monitor wouldnt even turn on.. just sat there on standby, like nothing was plugged in  :-\
4. he is now on the second J-Pac and this one seems to be faulty now too, the controls dont work, and the keyboard wont work if its pluged in to it. and the LEDs dont come on.

i have no idea what's going on with the PC and why we need to press F1 to start..
i have a theory that the monitor rolling is maybe caused by faulty wiring, because the monitor controls have been removed from the chassis and wired up so they are mounted on the outside of the cab. and this all started to happen a little while after he rotated the monitor.  i could easily re-solder them, and do a better job, but i dont know anything about monitors and have a phobia of electrocution ;)

and is there any way a short on the monitor could cause the JPac to blow??

so if anyone has any ideas on any of these problems. and any advice please let me know :)
thanks

If the PC is requesting that you press F1 to boot up, there is something wrong.

It would probably be worth removing the PC from the cab, using a 'normal' video card and running it without the JPAC.

Reseat all the components such as RAM, IDE cables and so-on.

If it's a modern PC, go into the BIOS and have a look at the event log. It should list any problems.

It could simply be that the PC isn't detecting a keyboard, and so gives the classic error: No keyboard found, press a key to continue.

You should be able to change the settings in the BIOS with regard to what error conditions it stops on. Something like: "All but keyboard" should do you.

With regards to the JPAC in particular, I can't help, as I haven't used one I'm afraid.

that's the problem with the PC.. i cant get it to work with a standard graphics card, it just doesnt power on the PC monitor.. and the Arcade VGA card with the arcade monitor wont display the BIOS screen, it's just a flickery blurr... so i'm a bit stuffed. :-\

i cant see that it would be a keyboard detection error (although i cant make out what it says so i dont know) because the keyboard works fine. it's just when it's plugged in to the JPac that it doesnt. 
Bursar:
If the PC won't work with a standard graphics card, then you've got some serious problems somewhere.

Is there a BIOS reset switch or jumper on the motherboard? Might be worth doing that and seeing if it helps.
keyamon:
there is a CMOS clear button that i did press but made no difference.
i'll get him to see if he can find the make and model of the mobo and i'll try and download the manual.

although there is definitely something other than just the PC wrong with it, it's on it's second jpac (soon to be 3rd).
