HP Officejet.Pro 8600 LCD screen unreadable

HP Recommended
HP Officejet Pro 8600 Plus

The problem is not necessarily to do with the screen. Before ordering and replacing the screen, first try removing then re-inserting the two flat tape cables that are connected to the screen. I believe the problem is a result of "dry sockets". The action of removing and re-inserting the tape cables causes the connection in the bus to be de-oxidised! It would also help to spray with CRC LUBRICANT 150G CRC DRY GLIDE PTFE.

You can see how to remove the display by viewing the following YouTube tutorial:

I am very confident this will solve most issues. Feedback is greatly appreciated.

Hello, @MissJoy

 

Thanks for reaching out!

 

Did you update the printer firmware? If not please download and update the printer firmware from here: http://hp.care/2rNfJWr 

 

Also, perform a power drain on the printer:

 

  • Remove the cartridges from the printer.
  • With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
  • Remove USB cable, if present.
  • Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
  • Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
  • Turn on the printer and wait till warm-up period finishes and the printer is idle.

 

Please let me know if this resolves the issue, or if you require further assistance!

Cheers 🙂

It didn't work. I guess the display is bad. It doesn't make any since because I don't use this printer.

I have an HP Officejet.Pro 8600 with the same screen problem.  I also removed the panel, removed and reattached the cables and the problem is still there.  If I order a new panel do you think it would fix the display?  It looks exactly like the picture above.

Yes, I ordered a new panel and it works like it's suppose to. I think something is wrong or loose in the panel because mine would all of a sudden work and the next day it would be messed up again. Good luck!
