I have a cheap 27" Goldstar TV that I've had since '96 (no snide remarks, now), and I was trying to see if there was some control inside the set that would allow me to do vertical squeeze for the "anamorphic trick." My old RCA TV 27" that I'd had prior to this had vertical/horizontal knobs on the back, so I thought they could be inside on this set. Well, I took off the back (after unplugging the set, of course), and all I could see were two little dials. I found out these are sort of the "master" brightness and sharpness controls. Oh, jeez, I don't know what I did, but I CANNOT get the picture looking like it did before I messed with it. I have to adjust it darker than I did before or I get these thin diagonal lines that are visible in dark scenes. This is no real problem, since I can increase the brightness back to normal with the standard brightness control, but the focus...God, the focus... If I turn up the "master" focus as sharp as I think it was before, I really notice the horizontal lines in the picture, particularly when the camera is tilting up or down, and the aliasing is terrible. If I turn it down so the aliasing subsides somewhat, I lose sharpness towards the edges of the screen, though the center is still sharp. I found a somewhat happy medium, but the aliasing still seems to be worse than it was before I screwed with the TV, and I still notice the horizontal lines in the picture a bit when I never noticed them before. What did I do and how can I fix it myself? A better set is coming in the near future, but I'm stuck with this for now. Thanks in advance.
