SOURCE: Hitachi 51SWX20B's screen has 3d effect
You have a problem with the STK convergence modules. They're on the
center circuit board attached to an aluminum heat sink that's about 8"
long and 6" tall. You may be able to recreate the problem (hour glass
effect) by gently moving the heat sink (which the modules are connected
to). This gives the hour glass effect on the picture and the advanced
convergence screen. This is an indication that the modules pins aren't
solidly connected (meaning soldered) properly. Remove the circuit board
and clean the old solder off & resolder the modules pins to the
circuit board reconnected the board and then retest by again pushing on
the heat sink. The "factory" job was good enough for 3-4 years
but the heat (and these modules do create a lot of heat) and stress
created from repeated use eventually takes it's toll, weakens the pin
connections and our problem occurs. take the appropriate cautions
working around the high voltage of the set & use a non-conducting
piece of wood to push the heat sink when doing tests.
If soldering doesn't help, then the modules have died and need
replacing. Don't buy the $10 cheap ones. Most of them have
an upgraded version that is stronger. Also look for any burned
resistors in the vicinity of the modules.
Best of luck, hope ya fix it.

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

One or more of the projectors lights( my guess is the green one) are either blown or in the process of going bad. Have them repaired or replqaced by an authorized tech.

If the convergence is off more than 1/2 inch or so you can't adjust. you have a failure of hardware. most likely the output IC. This set has 2 outputs for convergence. Each output contains 3 circuits, Six circuits altogether 2 red ,2 blue and 2 green. The normal customer adjustment will only alow adjustment of blue and red. They should be converged onto the green. There is a much more complex adjustment in the service mode for Geometry and convergence. These adjustments are only needed when you replace a failed componnent like the output ic. These ICs have been upgraded several times since the production of this set. The latest and most powerfull version is STK394-160. If feel up to it I suggest changing both outputs and the corresponding output resistors. Then do a complete geometry and convergence alignment.

If the magic focus doesnt correct the issue you will need to install the Convergence repair kit for your model. You should be able to get one at the following link. Leave them a email or call if you dont see your model as they add new kits everyday or two.

CONVERGENCE SOLUTION
sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. , JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others.

focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution
