Already posted a little about this. U23, u20, and r127 blew the day I got champion pub. Ended up finding a short. I just replaced all the components stated. Turned on the game and heard the bong that everything is good. It's not.

Led203 blinks constantly and 201 and 202 are solid on. The dmd will not work.

Any advice is appreciated.

Do you guys really just hate me? It always seems like I'm asking stupid questions or something... I want this fixed. I'm pissed it happened on the first day.

Not a lot but $50 to the person who walks me through or has the correct solution. Will send through PayPal.

No one hates you...I don't think...

Remove all connectors on the MPU except J210.
Power on.
Now what are the LEDs doing?

LED201 is the blanking LED. It should go off a few seconds after boot. If it stays on, the CPU thinks something is honked up that may cause damage to the game.

At startup 201 and 202 should be on and 203 off. During normal operation led 203 will be flashing on the CPU board, 201 off and 202 on.

Have you checked to ensure you didn't blow any fuses like 601 or 602? What voltages/readings are you getting on the pins going into the dmd (j604)?

#6 7 years ago

@chrishibler - tried that. Still blinking. 201 still on.

@john - checking

@pinball pulled and checked all fuses. They are fine. Will check voltages.

#7 7 years ago

@john believe it was switch 11. Made ramp. That doesn't seem right though.

#8 7 years ago

What did it short to? Solenoid voltage?

#9 7 years ago

Dmd voltages
-117.5
-106.3
4.9
11.7
62.4

Top 2 seem low.

#10 7 years ago

Not sure if that was the problem for sure. I looked at all of the possibilities on the switch matrix. That seemed most plausible.

#11 7 years ago

Did u unplug any ribbon cables and put them back incorrectly?

#12 7 years ago

@skyemont - I have been unplugging. They have all been plugged back in correctly.

#13 7 years ago

Not too worried about the dmd. Would rather have the game up and running and then worry about that.

#14 7 years ago

Try taking out the CPU chip. Go in between each pin and sand it slightly. I had a doctor who which did the same thing and this fixed it. Sometimes the pins are not getting the connection it needs..

#15 7 years ago

just bench fire the cpu and check it first
i am sure you smoked some ic's

Do you have another game you can test the dmd in?

#17 7 years ago

You have isolated the CPU board by removing all the ribbon cables and the blanking led stays stuck on. At this point, there is no point checking anything else. The issue is within that board and that board alone. Perhaps there was some damage when you desoldered and replaced your old components.

If it were me, I would probably just buy a new CPU board.
Mad has one nos: http://mad-amusements.com/product.php?id_product=1821 but you need your CPU and security chip. Pinled makes a nice replacement.

Sorry of this wasn't helpful. But if you're already offering $50 may as well pay a bit more for a new board.

#18 7 years ago

If you send the board to coin-op cauldron Clive will make it as good as new. He fixed mine twice while I was looking for a short. Once I found the short he was able to stop fixing it, I guess I stopped frying it would be correct. It did need a new security chip each time.

Thanks for the suggestions everybody. Maybe it's because I'm stressed about moving or maybe it really is that I'm pissed about champion pub dying day 1....might just jump ship on all my pins. Got too much crap going on and I basically want to just sit and do nothing. Lol.

Time to put things down and chill a little. It always helps me to rest the mind for a while, then reattack a problem.

The blanking signal originates at the ASIC. It holds the AV board and the driver board in reset until power stabilizes and basic initialization of the CPU software completes. The signal goes thru R90, U5, and U21. All of those would be suspect in addition to the ASIC, but I wouldn't go there yet.

Use your logic probe to see if the data and address lines on the 6809 are toggling. I suspect they will be since the DIAG LED is pulsing regularly. But, it's important to know.

I assume that the DIAG LED is pulsing at a constant rate vice flashing a code?
