Title: NHD-0216K1Z-YBW: some lines are out
Post by: WimG83 on August 07, 2015, 08:57:08 AM
Last night I started experiencing some missing lines on my LCD display.
Please see the picture I attached of the LCD with the contrast adapted so that you can see where it fails.
What could be the problem?

Can you provide some information about what happened to the display before you noticed this?  Was the display dropped?  Was it in an environment near the upper/lower temperature/humidity range as indicated in the datasheet?
This typically doesn't happen by itself, at least not when all columns were once fine.
If none of the above is true, you may contact nhtech@newhavendisplay.com to setup an RMA to return the display to us for analysis.

Hello Michael,

Thank you for your reply.

I was working with this display on my Arduino Uno. I had to leave the room for a while, the computer went to sleep and when I powered it on again and uploaded a new sketch, I noticed the situation described above. All the while the display sat on my desk, it has not been dropped and I always store it in bubble wrap with the pins in a foam bar when not using it.

Temperature was around 25-30 C and humidity about 60-70% as is usual this time of year.
