My EZ1601-01 all-in-one screen is blank. I can log into it remotely and all looks normal, but at the actual machine, nothing ever appears on the screen. Is there anything that I can troubleshoot?

looks as though the user profile might be corrupt. Try booting into safe mode or another user log in. If you can access safe mode create another account. Reboot computer normally and log into the new account. If new account works then you have a corrupt user account that would need to be fixed or just transfer all data to new account and remove old account.

What are the BIOS versions and what are the mother board revision numbers?

the tv has to have the firmware to sync to the source first and foremost..look into your tvs menu to see if you are compatible with your device

yes you need to use it some times

look 3 inch under left side of screen is a wheel to adjust the brightness

Try attaching the external monitor to VGA port to see if you get the same problem and then post back.

If the firmware didnt help, then it is a hardware issue. You probably got water in the battery compartment or something.

Anyway you should call Logitech support for a warranty claim. Or, you can do it by taking a look at the following link:

Hope I was able to help!

HI! Here's what to do if your Logitech Harmony remote's LCD screen is going blank or is displaying lines.

1. Remove the battery, press and hold the 'OFF' button, and re-insert the battery. The screen will display 'Safe Mode!', or the 'Activities' button will be lit.
2. Connect your remote to the computer.
3. Launch the Harmony Remote Software, and log in.
4. Click "Downloads" at the top and click "Firmware".
5. The remote will go through the firmware update.
6. Select "Yes", and click NEXT to update the remote.


If the screen is still blank after you complete these steps, then it is a hardware issue and you should contact Logitech's wonderful support team, given that the remote is still under warranty.
