The LCD display screen is blank, back-light remains on. Powering off machine to power back on results in loud, abrasive rattle which seems to come from scanner. Unable to do anything with device.

When this happens the first thing you should do is check the connections to the LCD screen. However if it was working fine before this is most likely not necessary since they have to be connected properly to show anything. After that you would need to replace the LCD or the Logic board. If everything else is working properly then the problem is more than likely the LCD needs to be replaced.

No power when I turn the unit on

  1. Verify whether or not the date and time appear on your Brother machine's LCD. If anything is displayed on your Brother machine's LCD, then it is most likely receiving power.

    1. If your Brother machine's LCD is blank, continue toStep 2.
    2. If your Brother machine's LCD displays a message other than the date and time, please refer to the FAQ about the message being displayed for further information.
  2. Verify the Brother machine's power cord is connected securely to the power outlet. If you are using a surge protector, extension cord, or power switch, disconnect it and plug the Brother machine directly into the wall outlet.
  3. If the Brother machine is turned OFF, its LCD will be blank. Please make sure the Brother machine is powered ON by pressing and holding theOn/OfforPower Savekey. This key is located in the upper-right corner of the control panel.
  4. If your Brother machine's LCD is still blank, connect it to a completely different, known working power outlet. If the Brother machine powers up, then the problem is related to the original outlet.

    -OR-

    Confirm the power outlet is working by plugging another known working device (a lamp, radio, etc.) directly into the same outlet. If the other device does not work, the problem is related to that power outlet. If a wall switch controls the outlet, verify that the switch is ON.
  5. If your Brother machine still will not power on, please contact Brother Customer Service.In Case You Still face Problem and Need Online Assistance Then Please Follow Us For On :

Screen not working

Lisa-

I am sorry to hear that the new sidekick 3 is not working for your son.

Is the screen white, blank, or just hard to see?

If white, then the flex cable needs to be reseated.

How to fix a blank white Screen on a Sidekick

If dark blank, then reseat the lcd assy itself and see if it works

Reseat the Sidekick 3 LCD Screen

If hard to see the screen, then the backlight is dead. A new screen is needed for that.

Replace the Sidekick 3 LCD Screen

I hope that helps

LCD Display Blank

I have a sony cybershot DSC-S650, the LCD was very dark and could not see anything except if I pointed it at a bright object, everything else worked ok. I could take pictures but could barely see them in playback as well.

I took it to Sony authorised repair outlet and was told the CCD was damaged, they charged me USD $55 to repair it (in Quito, Ecuador)

The LCD screen on my HP PSC 1600 all in one printer is blank. It first would display the messages as mirrored images, then it would only work if the screen was down, now it will not display anything at...

I hate to tell you this, but it sounds as though the device itself is bad. HP offers a standard (1) year warranty. If you're printer is not that old you can call them and get the printer replaced. Depending on the functionality you lose with the broken LCD display I would either continue to use the other working services or I would just purchase a new model.

Hope this helps.

I HAVE AN HP PHOTOSMART 140 SERIES PRINTER. I AM NOT GETTING ANYTHING TO DISPLAY ON THE LCD SCREEN. I AM HOWEVER ABLE TO PRINT PICTURES BUT WITHOUT ANY DISPLAY ON THE LCD SCREEN.

If the LED display screen on your printer is blank please try disconnecting the USB cable from the computer and then disconnect the power to your printer. Reconnect the power to a different power outlet, and turn your printer back on. If the same issue occurs, your printer will require service. call HP support so that they can recommend you to a servicer that specializes on the product. Pls rate as fixya, thanks!!
