"No Display" blinking in Winner Paid window

[cigar]

I have an S2000 that keeps blinking No Display in the winner paid window. It keeps flashing from no display to the number of credits.  Any thoughts would be greatly appreciated!

Open the door and check the cables and ribbon going to the display above the bet one button.

The thread needs to be moved to S2000, a moderator does that.  The fault is in the VFD panel (the blue display panel).  The cables are either lose, or the display has gone bad.

I checked all the cables and they are fine. What's my next move?

There are several things that could be wrong:

1.  The VFD or controller went bad.
2.  Something on the netplex bus is causing the failure.
3.  Something on the mpu got fried.

1. there's not way to test this unless you can swap the display and controller with a good known working unit. (if it still doesn't work, then it is unlikely this is the cause)
2. for the netplex bus, you would start by unplugging everything netplex related except the display (validator, printer, progressive display).  If it comes up, then you start plugging in each unit until you find the fault.
3. Pull out mpu board and visually inspect for anything that looks damaged.

It is important to note that at NO TIME should you plug or unplug anything while the machine is powered up, you WILL fry other things if you do so.  So everything you are going to pull something out for testing, always do it with power off.

Thank you for the reply but that is way beyond my technical capabilities.
Looks like I will have to get rid of this machine.
Thanks again.

Slot machines aren't always use friendly.
Take a deep breath and perhaps start with #3.
Simply power off, pull out your MPU board and visually check it for anything that may look burnt or broken. Then firmly slide it back in and make sure it's seated. So really push it in FIRMLY. Then power back up and see what happens.
The guys may use technical language but can re-word stuff so you can do this step by step. At least try the steps before selling the machine. It might just be a connector!
