stuck WEBOS Menu stucks on LG 55UF8500

[Fernando Custodio de Macedo]

I have a problem in my LG 55UF8500

When I watch TV, the imagem is ok. But when I open the Smartv menu,  the frames become distorted.
Has anyone had this problem and should help me?

I tryed a donwgrade with  Simon's LgDTVUpDater , but doesn't work. I think what my television has a Brazilian or Latin American  firmware and don't recognizes  in this software.

Ps. I did the fatory reset, but the problem persist

Hi Fernando 

I too have this very same problem with my LG 55850V it seemed to arise after TV updated to newest software 04.05.50 

Can watch tv channels ok when use webOS menus it displays many graphic artifacts,  jumps around and flashes same as your video 

Did you ever find a solution to this problem ?
