Quoted from Antron77:
So my Hobbit has been out of commission for about a month now. I have had the game since March, second owner, the game had about 100 plays on it when I got and has a little over 1000 now. Looking to see if anyone can help. Need a different set of eyes to see if they can catch something we didn't. I have spent about 10 hours troubleshooting this with different JJP tech support.
One day it was working fine, never had a problem with booting up or crashing mid game. They next day I go to turn it on the game doesnt boot correctly. The big lcd says no signal, the small book lcd turns blue and says VGA upside down, the playfield lights dont come on, nor does the topper lights. The IO board lights turn on, the amplifier board lights turn on, all the small boards mounted underneath the playfield lights turn on, the mother board fan comes on, as well as other power like the coin door lights.
Troubleshooting I did was got the multimeter out tested the voltage on the motherboard battery and the 12 pin connector seated on the mother board. They tested fine, 3 volts, 5 volts, and 12 volts all where they are supposed to be. Tried the jump start with a paperclip and didnt work(although mine has a wire basically built in as a jump start, pic below). Took off the big lcd screen and hooked the game up to a separate monitor which wouldn't boot. Reseated the long green chip on the motherboard(forgot the name of it). Basically reseated every connector in the backbox and bottom of the cabinet. Everything looked fine and nothing helped.
So I sent the motherboard into JPP since thats what they suggested. Said maybe it needed to be reflashed or the BIOS restored. JPP said the motherboard tested fine and there was nothing wrong with it. They sent it back, I put everything back together, booted it back up and still has the same problem. JPP mentioned it might be the power supply but I dont have a back up one to test. Although the 1st rep I worked with kind of ruled that out as the motherboard voltages were all reading right when we measured them with my multimeter.
So here I am asking for any suggestions. I am out of options other than calling back into JJP again to start troubleshooting anything we might have missed. Please help if you can think of anything. Thanks!

I had a WOZ go down and it was a connector that I did not notice had come out - I was chasing the CPU board for a bit and like somebody else said it was a power supply board - get this part amazon.com link » and see if you can rule out the power or rule it in as the issue. For me the telling sign was the fans would power on for a second then kick off. Also I did the reseat of the memory prior to finding the power issue, and did not seat that back in well, so once I solved the power supply issue I found I had created another that acts in the same way, so if you reseated the memory prior to sending out you should be fine as JJ checked your board, if you did it after try that one again as well.
