MX2610N No Display

[hellcat]

Have a customer that has an MX2610N the machine works perfect the touchscreen works its prints copys etc.. However the display is totally black and appears to have no display at all.

We have changed out the display panel as a whole, the flat ribbon cable the scn pwb, mfpwb, network board, sd card, memory, all 3 power boards and pcu board, with a donor machine that has 15K on it we have that runs fine. Nothing we have replaced makes any change at all and we are running out of ideas. All voltages seem to check out so it doesn't make sense at all. Any Ideas?

I'll give it a shot MFP sd card memory has all been checked and that isn't it. I'll give the driver pwb a try we also have all the optional equipment unhooked right now.

As we did have about 2 months ago a machine that wouldnt boot up due to a bad sensor on the paper deck lol weird but just came by fixing that one by luck. Unfortunately I dont think its the same problem on this one as the machine is still working unlike the previous one.
