Hi
Today I turned on the pinball and the DMD is only halfway: /
I do not know where to look for faults

I already did, and still nothing :/

I noticed that on the PCB with the fuse F2 is not led

I do not know if this is related to the malfunction of the display, but the ship stopped working.
In the configuration of the test, do not work

This is a LED display,
I changed the cable and still the same, whether the display could be damaged ??

The ship is already running,
the display is still a problem :/

how to disconnect the cable from the display, it leaves only the power that the display operates on the entire surface,

U55 can be damaged?

how to turn off the pinball,
  is the fraction of a second display illuminates the entire surface
