[Solved] Variant 8 screen video won't stop scrolling

Post by zexuy » Thu Nov 02, 2017 6:51 am

Hello,

I'm building my second gbz and bought a 3.5" composite screen from aliexpress - link below.

https://www.aliexpress.com/item/3-5-inc ... 3f09c95771

The screen turned out to be a variant 8 and required the 5v mod, which was easy enough and turned on straight away.

However the video keeps scrolling and I can't figure out why it's doing this and if there is a way to stop the scrolling. Is this a config.txt setting?

Appreciate your help.

Reattach the lcd ribbon, make a video of the problem and post the framebuffer resolution and sdtv_mode parameter values in the config.txt.

I switched to sdtv_mode=0 and managed to solve this last night.
Thanks
