Ok, this'll be my first post. Let me just say that I've been reading this forum for a week or two and I am very impressed by the depth of knowledge all of you possess and the level of maturity demonstrated by the members of the board. This really is what a board should be. I've been trying to decide on some kind of 5.1 package and I've learned a lot. I think I'm going to have to settle for the Kenwood HTB-504 for now. ANYWAY, I've got a 27" Panasonic CT-something or other (model # escapes me and I'm at work, C27D10? pretty basic, no PIP.) It was a floor model. From the time I bought it approximately a year ago, I've noticed that when I play VHS tapes (standard JVC 4 head VHS) there is a thin white line that looks similar to what you see when you over-adjust tracking on a vcr. It's thin and at the bottom of the screen. It only happens with tapes and the VCR did not do this to my old TV. I currently have it hooked to the tv with component cables, I have used the co-axial cable and it doesn't make a difference. My Playstation and now my my playstation 2 plays games and dvds without causing this problem (and I've had component and S-video with the PS and S-video to composite with the PS2). Is it that there's some sort of sound data or something that appears below the normal viewing image and the horizontal orientation needs to be corrected? Does this mean I have to figure out how to get into "service mode" and, if so, what are the odds of me hopelessly messing up the display once I'm in there? Or should I try to ignore it because, as my fiance says, I'm blowing it out of proportion and the INFURIATING LITTLE WHITE LINE is no big deal? Any advice would be greatly appreciated.
