Question about Hitachi 51UWX20B 51" Rear Projection Television

1 Answer

Double image/ out of focus with green and blue seperation

I have a five year old 52 inch Hitachi 51uwx20b that has a blurred picture with green and blue highlights. When you go to the menu, the image is doubled. Any idea what the problem is?

    Ours is 6 years old, sounds like the same issue. Though every time we monkey with the manual convergence it gets a bit better, when you turn off the tv it seems to reset to the crappy misconvergence again. Usually when we first turn on the tv, the misalignment is slightly to the right (or left-can't remember just at the moment) on the entire grid. By "resetting" to the initial settings in Magic Focus, that seems to bring it to a workable/easier fixing point. At this point it looks almost like someone has pinched ONLY the red gun at the lower left hand corner and pulled it outwards. Any suggestions on what could be causing that?

    same as above, but green has a "sway" down along the top of the tv. Does this also mean my STKs are bad and need replacement, or is the green projector dying?

Your tv is crt-based and is out of convergence. In other words, the settings for keeping the Red, Green and Blue images aligned have drifted and must be reset. This is common with CRT projectors and CRT rear projection tvs.

Refer to your owners manual for instructions on re-aligning it.

Replace the convergence Ic's with a kit that is available through your local parts distributor

You must replace all resistors in the kit
If you are not good at soldering and de- soldering have a local tv shop do it for you

Good luck

Double image


Problem seems in convergence out section.

TV needs Convergence Out ICs replacement.

If you have TV repair experience and know good soldering work then you can give it try OR get help of qualified TV tech to fix it.

If you need further help, let me know.

Double focused, red and green, bow in picture top and bottom


hi
You have a convergence problem
If the set has auto focus and will not complete its cycle.
The Auto focus module is bad, (expensive)
If it completes and the problem is still there.
Then check for bad conv. drivers (stk****) or cold solder joint on one or more of the 3 drivers pins.

Hitachi 52 projection tv


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.
