    [Electrical] MX-2310u no initilization - display light

    Happy new year,

    Customer sayid that first time hapend afther an electrical shock. And from then on the machine is randomly not starting or not waking-up, when it does that only fans can be heard and the led from display is lighting, nothing else. In the last week it dint start at all so i did disasembled a new machine and tryed to replace PWBs and it started so i put back his own boards and it worked!!! I dont belive that machines repair themselfs so i expect at any minute to get a call from customer that the problem is back so what do u think i should do?

      Try replacing the 2 DIMMS. I have also seen LVPS go bad on these but when that happens, it is completely dead, no panel what so ever.
      Failing to plan is planning to fail!!!

          This is quite common here, surprised no-one else has mentioned this yet....


          If the machine does not boot up (but has fans running), the cause can be either the Memory/HDD, SD Card, MFP, Firmware or AC/DC Power supply.

          Check the following in this order:
          There is a small RED LED directly under the CPU heatsink on the MFP board. If this is lit, the problem is the SD Card. Replace it with spare parts version. A regular SD card will not work as it is not partitioned correctly. Spare parts version must be used.
          If the RED LED is NOT lit, the SD Card & Firmware is OK. Then check the 4 LED's near the top of the MFP near the HDD SATA cable (D22-D25). All 4 LED's should be lit. If any combination of LED's is lit or flashing, check service manual Section 6-37 for info on which combination of LED's are indicating which particular error & hardware problem.

          =^..^=
          If you'd like a serious answer to your request:
          1) demonstrate that you've read the manual
          2) demonstrate that you made some attempt to fix it.
          3) if you're going to ask about jams include the jam code.
          4) if you're going to ask about an error code include the error code.
          5) You are the person onsite. Only you can make observations.

              Funny thing is that now is working so i will have to wait till error will come back.

                  Before digging to deep, I'd be checking the firmware on that.. Theres a lot of updates for that model

                      I attached a little thing we had to do on Sharp training. It has the fuse errors and the MFP LED trouble shooting. I apologize about the first one on DIMM1. I have no idea why i put B. I think it's supposed to be "on" The fan is also "on". I apologize for the chicken scratches.
