43fdx15b Hitachi 42in rear projection tv. been a great tv. I think it was jarred, and now the left side of screen has red vertical lines, farther apart on left side, getting closer together and disappearing in the center and right side. the Magic focus button works for the other colors but seems to lock up on the red. Help?

sounds like the convergence is out of whack. you will need to call a local repair shop and see if they can realign the color guns inside the unit. this is actually a really common problem with moving a rear projection screen.
This can be caused by a few things. The red crt/picture tube is going bad, which it would have to be replaced, tube can cost anywhere around $195 and up, if it is available. Another problem can be a bad transistor or IC on the red crt circuit board. Either way it should be taken to a repair shop. The average cost for repair could be over $300.
Replace Both of your STK ICs they are your convergence ics they are big black ICs will have Part# on them for example STK392-110, if they are 110s use 180s, if 020s use 040s other wise replace with exact same number. To get Parts call Electronix 1-800-223-3205
