The blue light just comes on the bv with the + on the vehicle. It would do that even before until the entire machine turned on. Then it would cycle when it was working before.

With the MPU removed when you turn on the power the BV should be heard cycling.
If it does not you may have a power supply problem. ( The one behind the reels).
You can try reseating it and then see if the BV cycles with the MPU removed.
Either way I'm assuming it is cycling and we are down to the MPU. You can try carefully reseating the chips and making sure the coin battery has at least 2.9 V.
You should also remove the green Varta battery following directions from this link:

Sorry for the delay. I removed the varta battery and U16 off the 1270 board. Unit still won't power up with the mpu board installed. Does anyone repair the 1270 boards or have a replacement one for sale? Thanks Matt

If you pull the 1270 mpu out and power up the machine the BV should still cycle, does it?

Matt · « **Reply #24 on:** December 26, 2021, 11:03:46 AM »

The BV did not cycle with the door closed and the mpu removed. The blue light flashes on the BV. The upper monitor comes on and says initializing. Displays Netplex link is down.

Check the power supply behind the reels.
BV should cycle with no mpu and door open.

Matt · « **Reply #26 on:** December 26, 2021, 12:05:21 PM »

I did pull the reels out and removed the power supply and reinstalled it a couple of times. Keep getting the same result with the BV

qbert · « **Reply #27 on:** December 26, 2021, 12:29:03 PM »

So it doesn't cycle

Matt · « **Reply #28 on:** December 26, 2021, 12:38:32 PM »

Correct, BV does not cycle.

qbert · « **Reply #29 on:** December 26, 2021, 12:40:01 PM »

Remove the BV reinstall the CPU and see what happens

Matt · « **Reply #30 on:** December 26, 2021, 12:53:13 PM »

Cpu installed and bv removed. The upper monitor doesn't come on. All 8 lights on the cpu are lit. The 2nd green light down from the top is flickering.

qbert · « **Reply #31 on:** December 26, 2021, 01:02:12 PM »

All linked netplex devices, printer, BV, VFD, red LED display, and I/O cards. Any one bad will lock up the machine.
With the machine off reseat all of the I/O cards. Then try. If that doesn't help with the machine off unplug the printer. Then try. Just remember do not unplug or plug anything with the machine powered up.

Matt · « **Reply #32 on:** December 26, 2021, 01:09:38 PM »

How many I/O cards are there? Is that the card on the door of the unit?

qbert · « **Reply #33 on:** December 26, 2021, 01:12:47 PM »

There are 3 two on the door and one on the outside of the mpu box.

Matt · « **Reply #34 on:** December 26, 2021, 01:51:34 PM »

I reset all 3 I/O boards. Turned machine back on. Same result. I turned off the machine and then unplugged the printer. Turned the machine back on. Unit did not power up the monitor or cycle the bv.

Do you have any spare parts or another S2000?

Matt · « **Reply #36 on:** December 26, 2021, 02:23:25 PM »

The only other ones I currently have is a Ms. Little green men and Munsters.

qbert · « **Reply #37 on:** December 26, 2021, 02:25:43 PM »

Are they I-games or S2000

Matt · « **Reply #38 on:** December 26, 2021, 04:12:58 PM »

The Munsters is a S2000 I believe. .25 machine. Just doesn't have the upper monitor

qbert · « **Reply #39 on:** December 26, 2021, 04:40:47 PM »

The power supply behind the reels is the same.
I would try that
