Grove LCD RGB Backlight not working

Hi, I have a Grove LCD RGB Backlight that is only showing a blue backlight with no characters when powered up using an Arduino card. I tried running the hello world example but it stays the same (blue backlight).

Has anyone seen this before?


Is there a particle device involved anywhere? This is the Particle community forums. If so, post a picture or something. It’s very hard to say what your issue is without more of a description or pics.

Sorry, it does not have a particle device. Apologies for posting in the wrong forum.
