MX3110N Blank lcd screen

[MRK23]

NO LCD DISPLAY BUT MACHINE WILL PRINT, So far the steps taken have been replaced the lcd screen with the lvds pwb. Still no display, updated FR30u firmware through the network, no display. Have switched out all memory and eproms with a working machine at the office, no display. SSD card is good on the machine, all fuses are good on the PWB board. All the MFPC PWB led lights indicate the memory and SSD card, before and after are good. All I can think of doing next is wiring harnesses and the main board. Any Ideas or suggestions?

Try unplugging the USB pwb under the control panel.

We have had 2 Sharp copiers with blank display screens, both machines basically dead except for green light on op panel and a fan running. A MX-M5001 and MX-503 both had a paper clip laying on the ADF control board along with a bunch of removed pieces of staples. Hopes this helps someone because we had tried everything up to that point....replacing a bunch of $$$$ power boards and control bds.

Re: MX3110N Blank LCD screen, boots up with sound

Pull out MFP board make sure dims are secure and push board back in securely. I had a MXM503 working fine until I moved it from on office to another office via truck. Hope that helps before you go replacing parts.

replace the lcd screen the back light probably went out I had one do that. Take a flash light and if you can see the screen with a flash light. Replace the lcd screen

I'm pretty sure the display goes into the scanner pwb. The long one at the top in the back of the machine. I would start there if you have replaced the display. I have seen a scanner pwb go bad on the same model and cause the same issue.

I had a 2314 with what sounds like the exact same problem and it was a faulty SD card. Replaced it and it worked first time.
