I have my PS3 hooked up to an S2530 series Bravia LCD via HDMI and every now and again (totally random somtimes hrs apart) there's a split second glitch in the form of a thin horizontal line (usually a lighter colour than the source - hence it shows up) that flashes up on screen. I first noticed this watching a bluray disc and because it didn't happen again for a while I thought it could be a bug in the 1080i deinterlacing process. But I've since seen this happen on 720p feeds as well, the XMB, PSstore etc. I really have no idea what could be causing it. I did have some other processing issues via HDMI with some of the TV's advanced settings turned on but those were sorted out by turning those settings off. Could this be an electricity surge? (I use surge protector 4 way adaptors though)..Only reason I mention electricity is because on my old CRT I used to get an odd screen flicker whenever switched on my table lamp. (i'm still not sure what caused that though) Faulty HDMI lead perhaps? It was an ebuyer £2.99 job but tbh these cables are supposed to be pretty much the same all round..unless there's something i'm missing. Has anyone else noticed strange HDMI glitches with their PS3 or can offer some insight here? It's a small thing really but it's doing my head in. Cheers.
