sony 55xs955 scan lines??? (1 Viewer)

[Carmine]

hey guys, i recently adjusted a few values in the service menu of my sony rptv. those in particular are in the MID-5 category which are supposed to increase resolution. i'm not sure, but i think i'm seeing vertical scan lines on my high def channels. i have comcast with a scientific atlanta 8000 stb. like i said, i'm not sure if i only noticed this after the service menu tweaks or if they have been there since day 1. any info would greatly ease my mind.

thanks guys.
Carmine

Horizontal lines are usually some sort of interference.
