Newbie with Coin-in Jam problem

[burgr86]

I have been searching for a solution to my "coin-in Jam" problem and nothing so far has helped.  I have a Double Triple Diamond Deluxe with Cheese slot (s2000) and all of a sudden I get this coin-in jam error and have been unable to clear it.  I have followed all the tips on this board to no avail.
I have also disassembled the coin comparater and there is nothing jammed up.  Could someoneone PLEASE point me in the right direction?  One thing that I did do, was swap a power supply with another IGT machine (identical supply) because one of the two power supplies had failed (top one which disabled the top display.  After I swapped the supply that's when the error came up.  I checked all connections and made sure the supply was seated properly.  Any ideas are welcome and this is a great forum for newbies like myself.  Thanks.

wow...I've never seen so many coin error problems all at once...

Okay, your coin comparator has the 2 green wires on top of it?

you might want to make sure that your power supply is seated properly and if the power supply is from an older vision machine it may be slightly different i have used one in an s2000 before without problems but never on a barcrest machine

I would power it off then check the Door I/O board and make sure it is seated.
The coin comp and optics power and signals go through the Door I/O board.

Also a coin in jam could be the optics gone bad (not very likely) the Coin Comp basically signals the machine it is allowing a coin to go to the optic (coin good signal) as the coin is passing through The pair of optics are just below the coin comp
Usually the optics are behind a black piece of plastic you can lift off when the comparator is removed.

4 i/O tests Door input test standard then cycle throught until get coin in 1 and coin in 2
They should be 1 and go to 0 and back to 1 shortly after you drop a coin in (the machine will enable the comparator so it will go through the optics if the coin is a good one)
