Check your coax cable to be sure it is at least rg61. If you have old rg59 cable the picture really suffers...
Variable plasma picture quality
I've got my Panasonic plasma hooked up to digital cable. A couple months ago we had a lightening storm and the next day I noticed a grainy quality and lack of sharpness to the HD picture I hadn't noticed before. It seemed to correct itself after a couple days.
Then yesterday I noticed the same thing again, but this time no storm beforehand. My assumption is the cable signal is compromised in some way rather than the TV (at least I hope that's the case), but wondering if anyone else has seen this, what may have caused it, and what you've done about it if anything. I don't have another hi def source to use for comparison.
By the way, I don't have a power conditioner/surge protector hooked up yet but will soon. Thanks for any thoughts/insights.
