My parents have a really old 45" Panasonic TV. I'd guess it was purchased around the late 80's to early 90's. Think dinosaur. They are going to get a new TV, but this for a FACT isn't going to happen for about 2-3 years. The biggest problem with the TV is lack of focus. I am fairly confident that the problem is that over the years there is considerable misalignment with either a mirror or lens. Is this some sort of thing that I might be able to fix by myself with Avia and manually re-aligning things? I have never done such, but I am fairly handy with DIY (almost)everything. I know I probably can't match factory specs, but I think I can get it better than it currently is. (If listing the actual product number/name helps, I'll go look at the back of the TV) Perhaps this just is way beyond me....but since I have no experience with realigning TV's (I do with lasers! I thought I'd ask here. Thanks for any advice!!
