The magic focus will stop if there is a bad sensor and or a problem in the convergence circuit.

This set uses two STK-392-110 convergence chips--both along with any of the resistors that protect them need to be replaced and the set adjusted--I have repaired hundreds of these sets----


Confirm model number----and if you go into the customer menu and either red or blue will not move in any or some direction--the chips have to be replaced---LET ME KNOW WHAT YOU FIND AND I CAN GIVE YOU FAIRLY DETAILED INSTRUCTIONS ON WHERE TO GET THE PARTS AND WHAT IS INVOLVED IN THIS REPAIR.

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.

Out of focus


Rach, if it doesn`t move from green to red to blue in Magic Focus then there is a problem with the convergence IC`s and probably one or more support resisters. These components will have to be replaced, questions? ask away, BMW Rider

Hitachi 61SDX picture got dim shows Code 3


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
