Question about Samsung HLN5065W 50" Rear Projection HDTV-Ready Television
This tv will occationally wack out and the convergence (I'm guessing) goes out. It gets an extreme curve or concaved look to the green projection, to get that bizare 3d look. Most of the time if the set is warm, you can turn it off and back on quickly and it will be fine. Some times you have to do this a number of times, but once it comes back in, it can be fine for hours. If it does this when you turn the set on cold, it won't reset. But if you let the set on for while, and try it after it warms up, it will eventually reset itself. Does this sound like a problem worth fixing on an aging projection tv? I have a similar problem. About a year ago, I bought a new convergence board from Pioneer and installed it (after re-soldering the two smaller boards back on to the large one). now, the red gun seems to be acting up. it will be aligned, then shift to the left, it will usually stay there, but sometimes bouces back or even back and forth. I've gone back to the old way of fixing things and when I tap the front of the TV (where the board is), it will bounce into place sometimes. This leads me to believe that there's a bad connection somewhere....Any ideas. Thanks so much
RESOLDERING THE CONVERGENCE BOARD SHOULD TAKE CARE OF THAT
