Hi all, A friend has offered to give me a 60" Hitachi 60SX8B Rear Projection Television that's in need of service. While not a TV tech, I know enough not to get myself killed, and have been successful at some basic TV repairs before, so I want to give this one a shot. However, as it's a rather large set, I want to have some questions answered before I go through the effort of bringing it home, as it's not a small set. The story behind this TV is along fhe lines of my friend called a repair person, they came out, installed "something" and were supposed to come back and finish the job and never did, and my friend never called them back, and it's sat there broken for about the past year. I went over to look at the TV, and it appears to have no deflection correction/convergence at all (Green is relatively square, which is logical given that it's in the middle of the set, red and blue are relatively un-square, given that thy are firing on angles, that makes sense also. User convergence has no effect on either color/direction (lines don't move at all). My current thought is that there's a power supply rail for the convergence section that's bad - or does this model use an integrated convergence amp for all 3 colors? Before I go through the effort of moving this to my house, anyone have any guesses? In particular, I'm hoping someone can verify if there's supposed to be a convergence daughterboard (and if so, where it's located in the unit) as I want to verify that the servicecenter didn't fail to return a part to the set before I go to the effort of moving it.
