Display has gone suddenly

Postby ken yoo » Mon May 30, 2016 3:24 am

My touch screen display does not show anything, only lit.

Please let me know how I can check the cause of the problem.

When did you find that problem? After power recovery?

The first thing I would try is, Download the current touchscreen version
https://s3.amazonaws.com/ideamaker/touc ... .raisepack
to a USB drive, plug it in the printer, turn printer on. updates automatically.

Yes, after power ON from the off state.

Could also be a low battery, if it was off for some days or just recieved.
In this case, leave it powered on for the day.

I will wait for the day but I powered ON for long time just before display problem occurred.

That should be the low power of battery.
Use a wire to short connect the following two pin at the side of screen. It will physically restart the screen.

Is this connection correct?
I shorted these two pins and now the display became black out.
Before it was lit without any showing but now all black out.
How can I do more?

OK, now that you turned off the board, TURN OFF POWER, WAIT 60 seconds, THEN POWER ON.
LEAVE ON for at least 12-24 hours as your battery MUST charge.

You got into this state partially by user error, partially by some conditions.
The front LCD is a complete running Linux computer. It has a delay timer that senses the power supply coming on and then a relay time delays to ensure stable power that shorts an internal "turn on" pin contact. When you powered up, the backup battery was low from shipping and you somehow killed power before it completed booting or turned off, then back on rapidly. This confuses the computer and it cannot shut down (black screen but backlight on). When you hit reset using the wire jumper you simply turned off the computer from further running off the battery in a crashed state. Again, now, just ensure you power on and LEAVE ON until the battery voltage rises to a charged level.

Actually this is not the highly recommended way to reboot the screen, especially your machine is a newly received one which has reset button at the back side of the screen box, since there are too many pins at the side, a tiny mis-operation will ruin the electronic system. Open the side door and check the back side of the screen box to find it, a little round sliver button.

Hi, we have a similar but not exactely the same problem.

Our N1 had not been connected to the the power grid for a few months so the battery went completely empty.
When we wanted to take it back into operation, we had the touch-function only in the upper half of the display, the lower doesn't react any more but the picture is still there. I think, the area that doesn't react is about 20mm from the edge. The reboot didn't help unfortunately.
When I look at the settings I now see a battery voltage of 3,6V but I don't know, if this is enough.

Do you have any suggestions what to do?

Connect a wired mouse and test whether all the buttons on screen can work or not and whether it is able to complete one print with no issue. If so, then there should only be having issue with touchscreen but not other boards or cables.
