Hey all- Been trying to find a good answer and not sure I located any thread in here that addresses the same issue. Throwing this out there to see if anyone has any clue... I've had a Sony NSX-40GT1 ["Google TV"] since, I believe, 2008 and it has been great. Up until yesterday, the HDMI [both to my Bluray player and the XBOX 360] has worked flawlessly, but yesterday, while my daughter was watching a DVD on the player, I noticed that the colors looks grainy and heavily artefacted, with weird dithered gradients, pink stripes through things, and all sorts of other weirdness. If you stood back really far and squinted, it all looked right, but of course, that is not how you'd want it to work... Anyway, I was thinking it was just the player or something... Nope... Even if I was on the "No signal" screen, the borders of things had a pink "halo" of sorts... so I can't be the cable (there is no signal). Also, the XBox 360 seems to have a similar picture. I tried reseting the picture adjustments [no change]. Tried turning off smoothing and while correction, etc. etc. etc. Nothing makes a difference. If I am in the menus or watching Netflix, it is 100% fine, but any input [including the Blue screen saying that there isn't any signal] has there graphical artefacts. Any idea what to do? I was working perfectly up until yesterday and no matter of switching cables, plugging in one at a time, turning/unplugging the TV, etc. seems to make the slightest difference.
