I killed my Freddy Pinball before ever getting it working :(

Disregard the previous message about the light board connector... I resolved that issue...

I just brought this Freddy Pinball machine home. Finally got all the wires hooked up. Somehow I had the wire that goes to the bottom of the "Power Supply" board swapped with a similar pin connector that goes to the top of the "Driver Board" (see photo named "connectors").

When I turned on the game, it just hummed and made smoke. I pulled out all the boards one by one and examined them for bad capacitors, broken solder points and/or burn marks... I did find burn marks only on the "display Controller" board.

Now, the game wont start, no display on the LED board, no nothing, just lights on the light board and playfield. Power supply (inside cabinet) makes noise. I have also checked the 2 fuses just inside the cabinet to the right of the coin door. I really dont know anything about these machines.

Is it possible that I could either "re-cap" the bad dsiplay controller board and everything work again? Unfortunately, I cannot bring the machine anywhere for service; I will have to have someone come on site at my expense.

I've been waiting for this pin for over a month and I screwed it up before I even got to play it at home (yes, it worked perfect before I screwed it up).

Please help.

those zener diodes look burnt but you have to check with a dmm..

do you want to learn yourself to repair or not ?
it not, just search someone who can repair the boards and ship them to him

if you want to repair - check the schematics, see what you messed up
find out where you put too much voltage (or voltage in where it should be going out)
and measure every component with a dmm to see if it works or not

and components may be broken even if they still look good
and components that look burnt may still be good, or have nothing to do with this problem !

first measure the big metal transistor on the powersupply if that still works
and try to identify if the connectors you switched on it are power in or power out

Thanks Aeneas for the response. How do I check the transformer? I don't even know how to use my multimeter.
Also, my F5 and F6 fuses are bad so I guess that would be a place to start.
 
replace broken fuses (with correct value !)
if that doesn't repair the game and you don't know how to use a dmm and measure diode/resistor/transistor then get help or ship the board to someone who can test and repair them..

where can I find a 3/8 fuse? I dont think radio shack or home depot has them.

anyone in the DFW area good with these machines?

thanks again!
 
OP: I have no protips for you, but I just wanted to say that I feel your pain and am sorry for your accident.

Last year I bought a fully working X-Files for $800, and while changing a flasher with the game on, the bulb housing sparked off the filing cabinet assembly, sending a charge right into the switch matrix and frying damn near everything. The total cost for me to get it fully working again? $600.


Well, maybe I DO have a protip for you, NEVER work on a game while it's turned on.
