I have a brand new 1 week old rptv it is the 42" toshiba cinema series hdtv widescreen. Its 42hdx82 i think or something like that. Ive done the manual convergence about 3 times and its still not right. It seems fine and then the next day its totally out of wack. So i adjust again and it looks great. Next day its back to the way it was. I thought maybe it needs a full convergence. Would that make it not hold a 9 point for longer than a day or is it not holding because of some other reason??? And if it is messed up should i call the techs for free service or should i return for a brand new one which will cost me $50 to do. Also i wondered if i should be worried about the flicker issue with this model? Is it really common or not???? Thanks for the help.
