Blurred picture or not clear picture


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo2_bing.gif STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

My mitsubishi vs-60705 has very poor picture clarity. It can be described as hazy and the color is weak.


It may be a convergence problem...but not sure based on your description.

Picture of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

48" rear projection hazy/bad picture


most fluid changes would fix that. I recommend doing all three but that's just me. Also make sure the crt's are full as this would cause the set to be out of focus. also make sure you don't move the yokes too much because you can knock the convergence out pretty bad and also have a blurred pix

FOGGY-HAZY PICTURE


The contrast setting should always be more than the brightness setting, it's purely common sense to have the black levels dark and the white levels light. I advise your brightness to be 40, and your contrast to be set to 60.

You shouldn't alter the hue, as most manufacturers would have spent significant time balancing this anyway, so set this to 50 and leave it alone.

The saturation shouldn't be altered too much, the best bet is to set this to 55 and let it be. Also, the colour temperature shouldn't be changed atall, so set this to the default setting and leave it alone.

As for the sharpness setting, this should definitely be set quite low. I advise setting the sharpness to 40, and the reason for this is most people assume that the higher the sharpness the better quality and detail, and they're completely wrong.

If you do what I said, you should end up with a crisp, smooth and colourful picture.

Picture adjustment questions


*The brightness control setting determines how bright your picture will be. *The contrast control sets the gain of the video circuit. This determines the difference between dark and light scenes. Low contrast settings make the picture "hazy". High contrast settings make the picture more distinction between dark and light scenes. *The sharpness control determine the frequency response of the video circiut. High sharpness settings give better resolution but also shows more noise in your picture. Lower sharpness settings smoothe out the picture removing noise but also fine detail. It needs to be set for the best all around picture. *Picture Enhancement is pre-set adjustments which give you different picture qualities. You just select the one you like. Stargazer
