Blank display on 3050/4070 models.

[Bgorby]

Having trouble getting the display to work on two machines. Pretty sure the problem is with the CN33 connector on the MFP/SCN PWB.
Reconnected numerous times. The home light comes on The error LED is on display remains blank. Any ideas?

SD card? Seen this alot on this site for that issue.

I would agree with the card but I believe this machine has the Msata card instead of the SD card

We have 11 of these units and 5 of them have had bad mSATA cards!

Good luck.

Okay! Will try MSATA.

Re: Blank display on 3050/4070 models.

Just to let you know, when the mSATA goes bad the display is dark and the power indicator light (small green light next to power button) flashes. Have had a bad mSATA give E7-80 and 90 codes also prior to it failing..

Good luck.

I have tried an Msata , still no display.

I had a similar problem but replacing the mSata fixed it. take a look at page 7-39 in the service manual. It may help you isolate the problem.


Oops, I just realized the Tech Tip earlier addressed this...

I am going to have to get some Msata preprogramed. We are getting more of these machines out and haven't had any issues yet but if they are having the same issues as the SD cards I had better be prepared.

One thing you can try, is put the machine in a CN update. if the screen comes on, then not your ops, or the LVDS pwb. Since you did the SATA, then the next step is the MFP/SCN PWB. good luck.

Going into Emergency Firmware to check panel is a great trick, however beware that the Emergency Firmware switch when turned on.....bypasses the On/Off switch on panel of machine.

Learned this the hard way.

hi,
I had a similar problem before. after replacing mfp-scn pwb & lvds pwb problem fix.

Re: Blank display on 3050/4070 models.

We had three machines with similar problems.
Two were just CN33 not getting "seated properly".
The third does have bad MFP/SCN and mSATA PWB's.
I would like to thank everybody for your support.
