Question about Hitachi 51UWX20B 51" Rear Projection Television

1 Answer

Seems like a convergence issue has begun

I have tried the auto Majic focus process which failed to correct the picture. I them changed to manual mode. The users guide says to hit Select button to toggle to the colored line that needs adjusting. In hitting the select button on the control panal (multiple times) none of the lines became highlighted. The arrow keys on the control panal also did not move anything - although they do work to change the channel and volume otherwise. I do not have the remote so I cannot try that route. Help!!!

Is there a way to manually adjust the convergence on a Hitachi HDTV modol #43FDX15B?


Hi James,

If Auto Focus (Auto Convergence) won't complete the set-up stop trying to adjust it. There is a fault in the convergence circuit!! ICs have to be replaced and maybe some burnt resistors.

If you access the service set-up menu and try to adjust the "defective" circuit the Auto-focus may not work correctly after the IC's, etc are replaced. Experienced technicians know that the service menu allow easy resetting to correct the misalignment, etc. "First Time" technician can be easily misled, waste a lot of effort and never get a correct picture.

If you want to attempt the repair, buy the correct parts from a service guy that does this type of work. I suggest having the repair done by a local competent technician that is experienced with Hitachi Convergence Problems. It is considerably more challenging than changing a fuse.

Our Convergence Gallery shows a variety of Convergence Faults. If you live in Toronto, ON., Calgary, AB., or Vancouver BC. it costs $257 for Hitachi in home convergence repair.

Good luck.

"Perfect Focus" problem on Samsung HCN4727W


You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

bigraedog,

Your convergence circuit has problems. Due to the size of the screen there has to be a circuit which will correct the errors of the scanning of the beam. All tubes are a little different and the yokes which move the beam are also different as well as the fact that over time the parameters will change due to heating of the coil. Periodically the convergence (sometimes called majic focus) should be set to get the best quality picture. If your unit has lost the convergence menu you have an ITC222 chassis. This is a common problem with these units and I have a tip which will walk you through the troubleshooting process, where to get parts and how to do the repair. The tip is at http://www.fixya.com/support/r5119668-fix_convergence_problems_rca_chassis .

Thanks for using FixYa and for the great rating.

Purple/Green Outline surrounding picture


I have seen two different things cause this. The first and most common is the electrical failure of one or both convergence IC's. A handful of times, the data in the DCU became corrupted and I was able to enter the service mode, go to manual convergence and correct the one location that was off.

Won't do HD, red for majic focus does not shift.


you need to replace both STK392-120 Convergence Ics. You can get replacement Ics at the following link and they provide free installation instructions so you can do the repair your self. Heres the link

Hi Dennis!

Your HItachi has an automatic color convergence (color beam alignment) feature called "Magic Focus" which can be accessed from the set-up menu. When selected, you will be prompted to push the front panel "Magic Focus" button... do so only one time and do not hold the button in more than three seconds to enter this mode. The process takes about 90 seconds to complete, but a second push of the button will stop the process with no change.

If the convergence is still bad after the auto-correction process, then the guns are misaligned beyond its corrective capabilities, and would require manual convergence.

A service manual detailing how to do this is available for a nominal charge at http://www.how2files.com/bykey.php/hitachi.

If you don't have one, a free download of the user's manual is available at https://merchant.satisfusion.com/sf/WarrantyCenter/registration/secure/Hitachi/Manuals/ModelNumberManualLinks.jsp?masterModelOID=SF-990486114-595&random=1213688278588.

Hope this is helpful, let us know if you have any other questions, and good luck!

Thanks!

Majic focus code gave me a five


Barb, thats a code for convergence error, the convergence circuit has failed, the IC`s will have to be replaced and may have 1 or 2 resistors burnt, this is not a job for a "layperson", board has to be removed, IC`s and possibly resistors un-soldered , removed and new ones re-soldered in, requires accurate voltmeter, soldering equipment and the ability to solder very small joints, I`d advise you to call a tv tech for this one, hope this helped, BMW Rider

Camera will only focus in macro mode


Check house not inadvertently set it to macro. If it has manual focusing try to reset the focus collar - check the manual for something you may have overlooked Failing all that look up the Fuji Tech Support team in the website
