NEX-5R screen flickering.

[Ozi]

Hi all, 

First of all I want to apoligize that my first post is about sharing a problem, but I did not found any solution nowhere. The problem is the screen flickering on my NEX-5R. Problem started while ago and was only sometimes while focusing (auto and manual) now the screen is flickering even when camera is untouched. Below is the link to recording of the problem that I put on YT. One short video is more than 1000 words. If anyone can help... I tried everything with cleaning the connection pins on lenses and camera, cleaning the sensor, turning off the front curtain shutter option (many people had some problem with an camera error occurs while focusing and camera reset)... Some time ago someone suggested even to go back to older firmware wich i did succesfully but no changes.

Thanks for all suggestions.
