Did you run the display test from the coin door switches and get the same result?

Did you reseat the wiring on the MPU board? IJ5, IJ6 and IJ7 connectors on the top of the MPU board.

Check the voltage at the display board side of the connector. It should be 100V.

Since you have power there, it probably isn't the issue. But I'd check the power at the connector that provides power to the displays:

The easiest way is to swap it out with another one, that's what I do at this point

If you have a logic reader and the know-how then you can figure it out.

Can you clarify this -

Quoted from DEN:Yes on display test all displayes , , light up only.

Do the displays cycle through the #'s or do you just get the dot you mentioned earlier.

I have spares and there are plenty of folks in the US that can repair these boards, but not sure how easy this is in Europe.

By the way my wife and I wwere in Copenhagen in October and had a great weekend. Lots of good beer. Went to Tivoli and loved Vertigo!

Yes all the boards are the same only the game roms are different.

you can start by swapping the display board test and if you get the same result then the mpu/driver boards. The machine will boot and 'operate' with the JL roms so no need to switch them out until you figure out whats going on.

No you don't have to swap them out to boot the machine. It wont work properly, but will go into attract mode, run the tests and start a game. I was only suggesting this to save a little time if you are poking around testing various components.

Try your display card by itself first, then the MPU. I'd also keep the MPU/Driver boards together, no reason to separate them and risk any damage or wear.

If you do find its the MPU and want to swap the roms, you only need to swap the 2 game roms and not the Flipper roms. The flipper roms are actually the 'OS' for the machine and should be the same version for both of these games. Be very careful with the legs and take a picture to make sure you put them back in the right position.

The board is on a wooden panel, so no way to ground it to the machine dierctly.

Ground is from the ribbon cable.

Look at post #8.
