Colors on tv are seperating. looks like double images.


Hi, Try the auto convergence or auto focus to eliminate the problem, if this does not work, you may have to get the TV repaired, the common problem are the power amplifiers that correct the color convergence, that is why you get color shades or ghosts in the images.

Hi,

The term for an out-of-focus purple "ghost" image on a photograph is "Purple Fringing."

This is fairly common in Digital Photography.

In order to minimize instances of purple fringing you may incorporate the following:
Avoid shooting with big aperture (Small /f number) in high contrast compositions.
Avoid overexposing highlights (e.g. bright sky behind dark objects).
Shoot with a UV/Skylight Filter or a Circular Polarizing Filter. These protect the lens and also help to Get bluer skies and cut glare off reflective objects.
You could also use Post-processing to remove purple fringing by scaling the fringed color channel. This can be done in an image editor like Photoshop.

These suggestions will help in minimizing the instances of color displacement for you.
I will look forward to your feedback and positive rating.

Sounds like Calibration is needed on the projection internals. Your TV uses a rear-projection system and the problem is either in the imaging LCD Unit or the light filter. I see in a previous thread you have changed the bulb. You can invest in a voltage regulator to keep the hardware in factory condition.
Also you can burn a DVD of a stuck pixel remedy video and run it on the screen with full brightness and full contrast. This is used for plasma burns and stuck pixels on conventional Flat panel TVs but can repair color issues with projection systems. This therapy is focused on the imaging unit between the projector and the main drop of your tv.
please feel free to post a more in-depth description or any changes

Poss. convergence problem with Hitachi 53UDX10B Ultravision


You have convergence problem. Either bad connections on ics, ics are bad or voltages to convergence circuit are missing. There are no bulbs in this set. 3 picture tubes,red,green and blue produce a picture than when alighned(converged) correctly on top of each other gives you a color picture.When not you get the effect you are describing. Frst you can try the magic focus in the menu.

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

Blue arc extends acoss width of mitsubishi ws65869


The WS65869 is a CRT based projector, no bulb. It sounds like you have a convergence failure. The convergence output ic's will need replacing.

Two problems, first the menu appears to be burned into the projection, the bulb has less than 100 hours. Second when black is supposed to be projected it projects blue?


You have a bad lcd, you would probabaly have some blue lite leakage also. Any lcd projector should not be left on the same image for long periods, it wears out the pixels that control the lite thru. The blue lcd is usually the culprit.
