Can anyone tell me what i have ?

I just joined here to hopefully figure this thing out. I can't find anything with a Google search. Thanks in advance. I bout this a few days ago. Guy wanted 125 for it, drove an hour and wouldn't stay on so I took a chance for 40 and it had 7 dollars in quarters in it. Got it home. Fiddled with it and it stayed on for a whole day but now going off again. It's actually the moniter going off. Moniter and sound comes on for 10 seconds then monitor goes black. Any help to find a manual would be appreciated as I can't figure out what buttons do what either (if I can get it to stay on again). Again, thanks! The little brochure doesn't appear to be for this machine but it came with it.

Your first problem is that you got and LCD instead of a CRT..lol..

joking aside, plug in a PC or something with a VGA signal to the LCD and see if you get a black screen.. it could be, the LCD, the Pandora type box or power issues..you need to narrow the problem down..

The cab has external speakers fitted which are presumably connected to that little elf board via the jamma connector (I see no 3.5mm cable going to the monitor and it looks like it is just a panel anyway).
So with that said both the audio and video come from the little elf board so either that's wigging out or the power supply is, I dare say the monitor 'going black' is it actually going into sleep mode (no video signal).
