[triny]

Hi,javascript:void(0); I hope my english is understandable.javascript:void(0);
I have a Lg WF32A14T. I have bought second hand 3 years ago.
yesterday I have switched on and the image on screen has gradually disappeared.javascript:void(0);
It was like to fade the image and gradually disappearing until it became dark.javascript:void(0);
Everything else is working fine (audio,channels).
It is a nice TV and it has still old electronic components .
Any help will be really appreciated.javascript:void(0);
Thanks
