Strange Character display on LCD 763-24064WG-ATMI

[leandro_fred]

We bought 12 units of LCD Display model as bellow:

763-24064WG-ATMI
NHD-24064WG-ATMI-VZ#
240 x 64 STN-BL (-)

We are having problems with all of them. They display the same strange characters as the Picture attached.

Do you know how to fix this problem?

Do you have a troubleshotting for this display model? Could you send me ?

Please help me.

Post the code that results in that display. Read the forum guidelines to see how to properly post code and some information on how to get the most from this forum.
Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.

What should be displayed?

Please post a link to the actual display that you have bought. e.g. Ebay sale page.

Please quote the library and example code that you are using. e.g. U8g2 and
C:\Users\ ... \Documents\Arduino\libraries\U8g2\examples\page_buffer\GraphicsTest\GraphicsTest.ino

Since this is a T6963 style controller you have to select the appropriate T6963 constructor. There are a lot of pins to connect.
Copy-paste the constructor statement.

I am intrigued. How do you get a blue border to a magenta backlight ?

NHD have example code for an 8051 MCU

How have you wired your display ? Which Arduino ?

[leandro_fred]

Thanks a lot for your reply. I will try to get the code.
These LCD displays are installed on display board in batch controller call Danload 6000.
You can find more information about the Danload 60000 on the user manual https://manualzz.com/doc/11265003/daniel-danload-6000-owner-s-manual

The display should look like this one bellow :

it is repeating the first line. It should say DANLOAD 6000.
Do you have any idea to fiz this problems?
Best Regards

Your manual mentions Standish, Optrex, Old Optrex.
Your manual implies that the LCD comes with the DanLoad6000.

So why are you buying an NHD display from Mouser ?
Have you asked DanLoad for an equivalent ?

Have you tried selecting the different options by trial and error?

This is an Arduino Forum. So we are happy to advise on Arduino products, libraries, code, ...
Have you tested your display with U8g2 examples as suggested in #3 ?

If the manual had posted a proper Optrex part number, you could Google for its datasheet. And compare the random item which you have bought with the genuine DanLoad component.

Thanks for you reply. Danload 6000 is obsolete.

So why are you buying an NHD display from Mouser ?
Danload 6000 is obsolete. The manufactor does not sell any spareparts.

Have you asked DanLoad for an equivalent ?
I use this LCD displays as sapreparts for long time.

Have you tried selecting the different options by trial and error?
Yes, I did.

No. I didn't test.
