I had a problem with my TV colors not lining up. One day I turned it on and the green was out of wack. I checked this message board and replaced the STK chips, bad soldering and all led to me just giving up on that and buying a whole new Convergence Board ($185). I just plugged this in and though now my Green lines up okay, my red is out of whack. Is there something I am doing wrong? Can anyone help me? Did i miss a step? Frustrated......Bruce

If this is not resolved soon, the picture will start to bow from the top and bottom. This is a common rpoblem with CRT based projections sets and is in the convergence circuit. If you can solder, you may be able to resolve this yourself. Be aware that there are potentially dangerous high voltages present inside the set even when unplugged.
The problem can be as simple as poor solder connetions at the convergence ICs or defective ICs. In any case, these ICs are large and black and are marked STKxxx. If you can locate these, try resoldering the pins on the ICs. If that fails to resolve the probelm, replace the ICs.
Please keep us posted.
