LCD-OLINUXINO-10TS + A20-OLinuXino-LIME Pixel Problems

[HSA]

Hello to the Olimex community,

Before I begin, I want to let you know that I am new to this and I apologize if I risk asking questions that seem obvious.

We have in our integrated systems the A20-OLinuXino-LIME which controls an LCD-OLINUXINO-10TS screen.

I have noticed that on a large part of our screens, we end up with a problem while broadcasting our videos.

Indeed, a set of pixels disturb the video and that on most of our units.


Could you tell me if someone has already had this type of problem and if, is it a software or hardware problem?

Thanking you in advance

Give us some more information to be able the track the issue. What Linux image are you using and is it one of the official images from here: http://images.olimex.com/release/a20/ ?

I've seen such issues when a longer cable between the board and the LCD is used or if there is strong nearby electrical interference. What cable are you using? Is the one sold by Olimex? Can you show us a picture of the hardware setup?
