I've noticed that when I have no signal going to my video inputs, the black input screen steadily pulses in blackness. I only noticed it recently when I was playing a game with the room darkened. I played around in the menu a bit and messing with the black stretch values yielded nothing. Do your Samsung TXL2791s and AKAI clones do this? The easiest way to tell is to put in on a video input with nothing on. Then, lower the brightness of the set to like 1(I have the contrast at 40). The flash is very visible. It seems to go away as you increase the brightness. I normally keep my brightness at 37 but I may have to bump it up into the 40s to help eliminate the flashing. Anyone else having this problem? I've never noticed it during normal viewing so I'm not sure if this is the same flash problem from a while back people were discussing or something new. Thanks for any info.
