I have a 27" jvc flat tube tv (av-27wf36) and it has a few problems. for one, unless i turn the contrast level down pretty low, the picture will shrink and expand when there is a change in brightness (like an explosion in a movie, for example) there is also a dark kind of "line" running down the left side of the screen. its not very noticable but its there if you look hard enough.
is my tv messed up? or is it possibly a problem with the house wiring? I dont know enough about electonics to figure it out however, I do have a 3 year service plan on my tv. should I take it in tio get fixed?
