Thanks for taking the time to read this and if you have any relevant information I'd greatly appreciate hearing it! I am first time poster here so please bare with me if something goes astray -like how I almost sent this message in totally unfinished lol) OK, so I am having a hell of a time trying to diagnose the latest tech glitch my CoStar is throwing at me - after a fixed period of relative inactivity (around 13 seconds) my screen goes black - I turn red ):/ Let me say here that I have no screensaver on my tv, and the CoStar screensaver is set to off. So you will not be wasting time on an idiot (well, in this aspect anyway ) by continuing to read!! There are conditions that apparently apply each time this occurs. It will NOT EVER happen while there's any audio output; not while viewing video/tv (even while in PIP or with the CoStar's sidebar menu displaying ontop of the tv feed) or while music plays. Also, if there is any video being played without sound the screen stays on (tested w/cablebox output in PIP - not with any standalone CoStar video like Amazon/Youtube/etc.) The last exception is when a button is pressed on the remote - not the mousepointer via trackpad - but a registered key input from the STB's remote. So if I dont want to have a huge chunk of my screens real estate being wasted w/a muted PIP of live tv, I am forced to remember that I must tap any button that wont mess up whatever activity I'm engaged in. Sigh. It doesnt seem to matter what else is going on. If I am downloading or a site in Chrome is loading the screen will shut off and activity Ends. I am going to call vizio but thought I'd post this first since Ive spoken with a couple nice kids but feel like theres more of a tech savvy crowd on these forums If there's any more info I can provide for a potential troubleshoot feel free to let me know! I could write more but think I should resist rambling off potentially unrelated stats lol. Thanks again in advance!
