Question about Hitachi 53UDX10B 53" Rear Projection Television

1 Answer

Colors out fo alignment

Hi, My 53 inch Hitachi projection tv has been working fine, but now the projectors are out of alignment and the auto focus does not work to fix it. There is a concave or half moon curvature now, as though the entire projection was pushed inward. How can this be fixed, does this have to be manually aligned?

The convergence circuit is having a problem. This can be either bad connections at the pins of the convergence ICs or defective ICs. These are large black ICs attached to a heat sink and should be marked STK-XXX. If you can solder, try resoldering the pins of these ICs first. If that failes to resolve the problem, replace the ICs. The should be no additional alignment necessatry once the ICs have been replaced.

Picture is doubled and color has pink tint


The inherent problem with rear projection TV's.

It sounds like the projectors need balanced (or a lamp is failing) and aligned. The alignment can inadvertently be changed when the TV is moved, and seldom "just happens".

Any decent TV repairman can perform the required service. I would shop locally for one.

Turned on TV this morning and the colors were out of alignment. TV works just looks funny. Tried the magic focus and got most of the screen lined up....except the upper left hand corner where the colors...


There is a convergence output kit for this set. There are probably resistors in the convergence circuit that are starting to loose there values. If you are going to have the set worked on have them install the whole kit which includes the convergence outputs and resistors. Thanks

My convergence adjustment is not aligned


The fact that the magic focus doesn't work means your convergence ic's are shorted or bad

They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT

If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit

If you are not sure about doing this repair you should have your local tv guy do it for you

Yellow and blue color ruins total picture on 50" tv,can't get rid


lupe0112,

I'm no expert, but I think that you have a problem with the convergence of the 3 color guns. I've been working on a similar problem. As a first step, have you tried "Magic Focus?" The Magic Focus button for the Hitachi 53UDX10B is at the left of the small front panel controls that also include your RCA composite and SVideo connectors. Let the set warm up for about 20 minutes (as recommended by the user guide), and then press the Magic Focus button. When you press the Magic focus button, the set will auto align the 3 color guns. If this doesn't fix your problem, unplug the TV for at least 4 hours and try again.

Colors are separated on the top from the left to right


Probably the color convergence is off. I had a similar problem. Have you tried the magic focus button yet? That is located at left in the small front control panel. Power on TV, wait 20 min (according to user guide), then press the magic focus. If that doesn't fix the problem, you could try the service mode alignment procedure. But that's a little trickier. I don't have a link handy for that procedure right now, but will look for it if magic focus doesn't re-align your color convergence.

All color guns out of alignment


Needs convergence amps replaced. Sometimes resistors burn and need to be replaced. This repair requires soldering/desoldering equip. and a trained eye, but usually can be done for 175.00-325.00 at a reputable service center. Good luck, Russmann.

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!

the convergence IC`s and associated resistors have to be replaced, do not repeatedly push magic focus or the alignment after the parts change out will take longer which of course means higher repair bill, good luck
