IGT S+ Sizzling 7s 61 error question

[xpoc454]

I have a Sizzling 7s S+ machine that I have decided to focus on of three I received from an Uncle who has passed away recently.
I decided to replace all 3 batteries when I got them because the Sizzling 7s was giving a 61 error and the other two have 12 error.  I know they had sit for at least 7 years.
When adding the sizzling 7s original board back in I now get no error codes.  When I switch out the double diamond board into it, I now get a 61 error.

I used the process of clearing 61 mentioned in the above link. 
This is what I do, just to make clear:
Machine starts at 61
I push the reset key that is right next to the on/off button for 5 seconds.
Close door and make sure its all the way closed with latch all the way down.
Turn key on side of machine, which is a normal key and not a cylider key one time.
All I see now is the coins played light flashing 0 and 1.
The lights above the slot machine are as follows
Lower yellow is flashing fast upper white flashing low.
Ive done this technique multiple times and I never get the bell sound when I push the reset button (not sure if that is critical)

Is this at the point where I need to think about a clear chip? This machine does have a bill validator but the machine is currently on tokens and the validator is not connected.
Is there anything else I can do before ordering a clear chip?
I have read about clearing the cmos chip by pulling it and grounding it on metal than reinstalling it.
Also I have read about using another chip from another machine to clear than replacing it.

Are any of these of options applicable for my situation?
Below is some of the information from my 3 machines. I am trying to get at least one working from the 3.


I have 1 Double Diamond Date 2/1990
I have one Wild Cherry Date 4/1994
I have one Sizzling 7 Date 5/1993

Chips on each  board are the follows:
Double Diamond     Reel SS3442    GameProm SP731
Wild Cherry            Reel SS712      GameProm SP731
Sizzling 7                Chips have no stickers on them

I am sure I have forgot some information. Please be patient, its my first 3 slot machines.

Oops, stop right there.  Does the 61 message change to 61-1 after you press and hold the self test button (located next to the power switch) for a few seconds?  If it doesn't, you'll never get the error clear by continuing, and we'll likely have you try a clear chip at that point.  (You could also check the self test switch and its wiring to make sure the switch is actually working.)

Yep all three of my beat up hand me down slots had major issues. I bought the clear chip this week and started on the sizzling 7s machine.  It was working very good (other than the pull handle was able to be pulled anymore) until I won.
Then it tried to pay out through the hopper and got an error. But that is another topic I have on here.
