Good Day;
Would suspect the convergence IC's, replace both even though only may be defective. Good Luck, big IRISH.

Magic focus not working colors not aligning


If Magic focus will not correct it (it is the limited auto convergence for this set) both the convergence chips which should be stk392-110 or 150 will have to be replaced, convergence is done with the original remote with set in the Decam ( tech convergence mode).

The parts are not that expensive and TVrpairparts.com sells kits with instructions for these sets by model number.

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,

Magic focus, #5 Manual


Sounds like a Convergence IC problem, the convergence ics would need to be replaced. This can be done by yourself or a professional.

Hitachi 53uwx10b Convergence


You must have the original remote to do complete convergence adjustments. Remote method: Press MAGIC FOCUS button on front panel to start the magic focus. When magic focus is running, press MAGIC FOCUS again. STOP should appear onscreen. Immediately press RECALL or STATUS on the remote (must be pressed before STOP vanishes). The set is now in DCAM (Digital Convergence Adjustment Mode). Manual method: Remove the front grill and access panel or reach around from the back and press the little pushbutton located in the front left corner of the PC board, next to the Digital Convergence Module.
Once in DCAM, the remote buttons STATUS selects green, 0 selects red and ANT selects blue. 2,4,5 and 6 move the cursor and the thumbstick makes the corrections.Make all necessary corrections and then press PIP MODE. The words ROM WRITE? appear onscreen. Press PIP MODE again to store settings. When green dots appear, press MUTE to return to convergence pattern. Press PIP MODE (ROM WRITE? appears again) and then press PIP CH. This will Initialize the internal sensor data positions. When INIT finishes, press POWER on the TV and convergence is complete.

Hitachi 51SWX20B Convergence problem


Solution:

Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.
