several evo 128x32 same failure.

[dom69]

Hi all,

on several evo 128x32 I have the same failure.

it starts up very well, but as soon as you connect the colorization connector, instead of having the animations there is a nice screen with all the leds lit in white.

an idea ?

thanks in advance

You get this picture when you connect to a real pinball when pin11 on the dmd connector is always high instead of receiving signals.

Check the connection all the way to the processor for short circuits.

I just checked, the connection I have to the PB4 processor is good

but still white

[dom69]

very well I control it in the afternoon and I tell you

[dom69]

then result:

input test 1/3/5/7/11/13 ok.  

no short-circuit on any inputs between them and on the positive or negative

What is the colorization connector ?

[dom69]

So,

without the connector it's ok but with it it's not good

You are talking about the connecto of the ribbon cable going to the real WPC pinball DMD controller board. Right ?

Did you try a different ribbon cable ?

 

[dom69]

yes the cable that comes from the animation card of the wpc.  yes I changed the cable.  I currently have 3 evos that do the same.

Maybe a short circuit to the pins next to PB4 ? Hard to tell from remote. Did you check all joints with a magnifying glass ?

[dom69]

Well,

I checked with a magnifying glass if there was no short-circuit between all the legs of the processor and more particularly PB4, apparently not.

I think this one I'll leave it aside
