It would be helpful to know what device you are referring to in order to provide a more accurate answer. Please provide more details about the device with the time display in the upper left corner that is not working.

The command line is full. Use the left arrow key to clear the command line. Then erase all previous entries, or reset the RAM

I believe the "Caption Vision" is selected. By pressing the "Display" button on the remote it should toggle through the choices until "Display Off" appears. That should be all.

If your car have the command you must set all the clock function on command take the owner manual an read how to do it all the information in the owner manual if don't have the command, First ignition on, then have a look on steering wheel you have two multifunction switch group on your steering at left and right, get mileage display on press up page key on left switch group, keep eye on instrument cluster display then get setting menu and press up arrow key on same switch group, then use up and down arrow keys to select time and now you have to operate right hand switch group + or - key for increase or decrees time.adjust the time or date you need then then again up arrow key next step will appear time setting will set your time format,

It might not be the same issue, but we had a blue square in the upper left hand corner of our hanspree. To fix it, either press the button headed 'pip' or go into menu, down to calibration and then uncheck the box titled 'pip' there. I hope this sorta yours as it did ours.

You can try with disconnected battery ground cable, battery is fitted under front right side seat, whether it's left hand drive or right hand drive, if not work have a good look is there any switch stuck on command if one switch stuck it won't be operating, if one stuck after press you have to pull it back then it will work, is this information helped you

Hello,

When you turn the calculator on, its screen is cleared, save for a small square on the top left corner. This is the cursor and it is blinking: The calculator is waiting for you to order it to perform some calculation.

Try this simple operation
[1] [+] [1] [ENTER]. The calculator will display the result one line down justified to the right.

Hope it helps.

You may find it in your "Menu" button on your remote, search for anything similar to "HD Logo" and turn it off. Failing that, make sure it isn't stuck on with transparent plastic, haha.
