We've got sony tv of model KDL-32W706B (at least that what is written as a model) and mostly use it for wathcing youtube or movies from usb. But two days ago there occure sch problem: when movie or youtube video is clicked to be watched, screen goes dark and then tv reloads. We didn't do anything new with the tv when the problem occured, but then tried to reload and even reset setting, but it persists. What might be the case and how ot solve it? Please help, any ideas are appreciated!
