Hello, I have a game king multigame that does not seem to boot up. The person I got it from said the display likely works but the power supply may be bad. How can I verify this? I am attaching a picture of the lights on the MPU as well as a video of me turning it on.

It's booting. If it wasn't you'd have a red blinking LED on the MPU. If you close the door and give it more time it will probably boot up completely as long as there isn't some other error that you can't see.
I think you have a problem with your monitor. I see the green power LED is lit, so it's power supply is working. More than likely the inverter board or CCFL's have failed. When it happens all you see is a black screen like you have. I'd replace the inverter board first as it's not uncommon for them to fail.

Thanks for the reply. Would that be the board on the left in the attached photo? Is there a good source for replacement parts?
-
Yes, the one on the left with the High Voltage warning labels on it. Google the part number on it and you should be able to find one from one of the gaming parts suppliers, Spin, Happ, etc.
-
Also sounds like your MPU fan is loud. You may want to replace it. Its on the right side of the MPU case behind the bill acceptor.
-
Thank you both for the suggestions. I have an inverter board and an MPU fan on order. I will report back when I get parts in hand and have a chance to install them.

The inverter board arrived today and I installed it this evening along with the fan. I was able to see the screen for a while. Long enough to run a clear and setup/configure the machine. I was trying to work through a bill stacker error and now the screen is black again. I am wondering if it could be a loose connection somewhere.
I did notice a grey wire with a connector that is not connected to anything, but I don't see any obvious spot where it would go. Any ideas if it is needed or what could be wrong?
-
Well that's quite a letdown. I don't have a tovis monitor, so I'm not sure where the gray cable goes. Check on the inverter board for a SMD fuse. It should be labeled F1 or similar. Check it with a multimeter and see if it opened or not. If so, your CCFLs probably are going bad.
-
I have the same Tovis monitor. The gray wire you have is not hooked up at all on mine. The plug is open, no gray cable at all.
-
Thank you both for the latest feedback on F1 and the grey wire. I have measured F1 on both the original inverter board and the replacement board. They both measure intact at 0 ohms.

I'm not sure that the MPU is booting completely. You should have all LED's on except red. One of the first things initialized on the MPU is the watchdog timer. If it is running, the board won't try to reset itself, and you won't get the flashing red. I have not studied 039's very much yet so I don't know what the dark LED's are saying.
Do you have another MPU to try?

No, unfortunately, I do not have another MPU to try. But I can hook up an external monitor and see the screens. I just can't select/touch anything. When I hook up the Tovis monitor, it is black but I can touch it and hear it clicking on things.
-
OK. It's booting then.
-
Yeah, the 3902 boards and 044 boards from what I've seen are pretty good about getting the red blinking led when they don't boot because of software or another issue.
My initial thoughts is you probably have failing CCFL's since it worked a little bit and then died during setup with the new inverter board. Usually they will take out the fuse, but it may have taken out something else. Unfortunately, you probably need a new LCD panel, but it would probably be best just to find another complete working LCD monitor for it.
