DMD ghosting

[Pop Bumper Pete]

On my Stern Ironman, on the DMD display, some of the dots next to the dot that are supposed to be on also glow, muddying up the display.
( I am hoping that sentence makes some sense )

It has done this since new

Is it a bad display or fixable?

Have you tried cleaning the connectors Pete, may be a simple fix. But usually ghosting is a sign of a bad display, I have a few old displays here that suffered ghosting

I will give it a shot

Pete - Would still be under manufacturer's warranty ?

I should have gotten on to this sooner

I simply figured that it was maybe a bit of fluff or a plug not sitting right

There is a 9 month warrenty on the DMD, the game is a bit older than that

the DMD is the same as all the others, I have a new one, I will install it on the weekend and see if it is the DMD or something else

That's a good idea - it will isolate the issue.

OK
I swaped over the display for a new one,
Must have done something to it, it is DOA (probably looked at it the wrong way)

So went for the simple solution I should have tried first, I swapped over the whole panel (speakers and DMD) from the spidy sitting next to IM
(This included the cable from the CPU as it was more fimly glued to the display end)
Same issue on this board

So I am guessing something unfixable on the CPU board?
(as most chips are of the too small to be soldered by hand)

Probably the CPU board but if the voltages to the display are incorrect, they can also cause some strange display faults.

I have posted this issue on RGP, someone there has suggested the problem is on the DMD power supply board

I swapped over the DMD power supply from another machine

Still the same problem

maybee the dmd controller board?
