Where is the magic focus button?

Most Sony Rear Projection TV have a small door under the screen with some manual controls. Push on spring loaded door to open. Magic Focus is near the bottom and labeled.

If Magic Focus does not restore for correct operation, check the Convergence Gallery to confirm if you have a convergence fault that needs repair. #8 is the Sony menu.

Problem with focus (severe problem on upper left

The Convergence circuit needs to be repaired.
There is a pair of Convergence IC's that need to be replaced. Best thing to do is to call a repair facility unless you have a solid back ground in Projection repair.
Hope this helps,

Not focused

Please! Stop using the magic focus now!
There are internal parts that have failed and this requires attention by qualified personnel.
The more you hit the magic focus, the more the proper calibration points will go off the mark, since the computer only knows that the calibration is incorrect, but is unaware that the parts that DO the calibrating are defective.
Sometimes this will make the repair more difficult, since a major maual recalibration may be necessary if the registers "rolled over".
If no one had touched the magic focus and just called for repair, the set would just need the parts. Once replaced, the set would look normal. Yours will require a few more steps.

You will not be able to solve this yourself. It needs the convergence IC's replaced which is a big job.

One half of picture is distorted

to create the total geometry in the tv is needed a system called Convergence.Convergence amplifiers are damaged in this unit, magic focus cannot work because magic focus works to level computer and controls the amplifiers damaged. this repair is for a technician because an adjustment is needed after the amplifier's replacement.
