Title: FT810 White Screen Problem
Post by: EnsAltun on June 28, 2022, 09:57:57 AM

Hello,
I have a problem with FT810 graphic controller. I am getting white screen problem in every manufacture. Rate is 6%. Also I am checking all other components, solder paste etc. on circuit but everything seems ok. There is only one solution, that is changing FT810 with a new one.
Firstly i thought there is cold solder joints on pad of ft810 or solderless pads. So i desoldered ft810, cleared all pads and soldered again carefully.
But i get white screen again. Seems FT810 is damaged.
I need to find reason of this problem. Have you every seen this problem before? Do you have any idea why this can be happen?

Hello,

Thank you for your question, firstly id like to apologise for the difficulties you are having.

A 6% failure rate is high in this instance, would it be possible for you to share your boards schematic for review?
