You have a failed part in the TV's electronics, this is not something you can adjust out.

The picture is so dark can't make out figures


It sounds that the back-light section has some fault with your TV. Otherwise, 30% brightness, 60 to 65% contrast, and 20 to 30% color settings should give you perfect picture.

My monitor stays white it wont show any display


Hi,
black-icon.gif This icon indicates the BRIGHTNESS control, more properly called BLACK LEVEL. It adds or subtracts an offset, or bias, into the red, green, and blue signals. This control should be adjusted so that black picture content displays as true black on your monitor. Misadjustment of this control is the most common problem of poor quality picture reproduction on computer monitors, video monitors, and television sets. Later in this document, I will explain how to set this control properly. The setting is somewhat dependent upon ambient light. Modern display equipment is sufficiently stable that frequent adjustment is unnecessary.


picture-icon.gif This icon indicates the CONTRAST control, preferably called PICTURE. It applies a scale factor (gain) to the red, green, and blue signals. It affects the luminance (proportional to intensity) that is reproduced for a full white input signal. Once BRIGHTNESS is set correctly, CONTRAST should be set for comfortable viewing brightness.

The gamma can be controlled through Video Card utility which can usually be accessed by going to display properties.

Depending on your video card software you may be able to right click your desktop, select properties, select settings tab and then choose advanced, towards the bottom. In there you may find a tab called Monitor and under that tab you may or may not (depending on your video card software) be able to adjust your color correction settings(gamma & brightness & contrast).

. Right click on the desktop and then select Properties

2. Click on the Settings tab and then click on the Advanced button.

3. Click on the Color Correction tab and you will see settings for Brightness, Contrast, and Gamma

I have a sony kdf-46e2000, there is a pinkish stripe on the top and bottom of the screen, what is causing that?


Looks to me as an serious (but not uncommon) PSP board problem with Sony plasmas. Contact a Sony service center.

What problems have people had with quality control on these displays? Are they covered under warranty?
  1. Certain displays emitted an extremely loud buzz. This was covered by warranty repair.
  2. Certain displays had a problem with the Y/C delay on their S-video input. This was also correctable.
  3. One person reported red vertical lines on his display. Was this covered by warranty? Was it an input problem or a pixel problem?
  4. Afew bad pixels here and there are not covered under warranty. Largeclusters are generally covered. It's up to Sonys discretion. On the plus side, however, bad pixels are becoming increasingly rare. Mostpeople are reporting no bad pixels at all!
CALIBRATINGWhat needs to be calibrated on a plasma?
You needto calibrate most of the same things that need to be calibrated onother displays. About the only things that don't need to be done areconvergence and geometry. You can usually tinker with picture size andposition, but there's no need to deal with keystone or pincushionadjustments, etc.What is white level? What is black level? How are they adjusted?
Theadjustment for white level is usually labeled "Picture" (as onPanasonics) or "Contrast". "Brightness", on the other hand, refers tothe black level. Yes, this is apallingly counter intuitive. This FAQuses the terms "white level" and "black level", since they betterdescribe what you're actually adjusting, and they're the terms used byAvia and Video Essentials.
How do I adjust hue and saturation?
In another mysterious choice of terms, hue is controlled by the "Tint" setting,and saturation is controlled by the "Color" setting. This FAQ uses theterms "hue" and "saturation", since they're the terms used by Avia andVideo Essentials.
How do I set the white level on a plasma?
Youset the white level by adjusting the "Picture" setting. You will needto use a different test pattern than you would for a CRT. For both plasma displays and LCD displays, you should use the 10 IRE grayscalestep pattern. There are two criteria you want to match on your plasma.
First,you need to make sure the white level is low enough that your displayisn't thresholding (or clamping) bright levels. You should set thewhite level low enough that you can see each of the 10 IRE stepsdistinctly. The Sony seem not to exhibit clamping (in my limitedexperience), even at factory defaults, so this criterion may not beterribly useful.
Second, for the health of your display (e.g.to avoid burn-in), you should turn down the white level. Just becauseyour display can display blindingly bright pictures doesn't mean that it should. Plasma displays should be set between 21 fl and 25 fl light output; the Sony comeout of the factory at about 30 fl. On one ISF-calibrated Sony, 23fl was roughly equivalent to a Picture setting of -20 (in the usermenu, not the service menu). To set this precisely you'll need to bringin a calibration specialist, but you can do a lot of good by justdialing down the white level a lot. After seeing the display at 30 fl,23 fl will see very dim. But after a while, you'll find that 23 fl isplenty bright.
How do I set the black level on a plasma?
Youset the black level by adjusting the "Brightness" setting. You can usethe same test pattern you would use for any other display.
How do I calibrate grayscale (calibrate the color temperature)?
Unfortunately,this is one you can't do yourself. You need special equipment tomeasure the color. In fact, most ISF technicians lack the equipmentspecific to plasma calibration (a $15K gadget known as aspectroradiometer). But even the standard color measurement equipment(which calibrationists do have) will do a great job.
Thatsaid, one person who had his Sony display calibrated by an ISF specialist said that the Cinema / Warm setting was reasonably close to6500K out of the box. Using that setting is probably the best you'll doon your own.
If you're really determined to screw up yourdisplay, the RGB drive and cutoff settings in the service menu are used to adjust the color temperature.
How do I adjust the color decoder?
There are several issues here. Generally speaking, the Panasonic decoder seems topush blue a bit. The R-Y Axis Angle and B-Y Axis Gain in the servicemenu are used to correct this behavior.
There used to be aproblem on some Panasonics with the Y/C delay on the S-video input. Seethe Quality Control section for more information.
How do I adjust the gamma?
On the industrial model, there is a set of Advanced picture settings. Go to the Picture menu, turn Advanced on, and then hit the down-arrow. In the subsequentmenu you can adjust quite a few parameters, including select from a fewgamma settings.
This advanced menu appears to be missing from the consumer model.
How do I calibrate my consumer model given these missing menus?
Thereis apparently a way to activate these menus. Perhaps you can find acalibrationist or Panasonic technician would can turn them on longenough to do the calibration.
What's the overall calibration procedure?
In general, the order Avia sets out is the correct one. A more complete list is:
  1. White level (picture)
  2. Black level (brightness)
  3. Repeat (1) and (2) until you have a good balance.
  4. Grayscale (requires special hardware and mucking about in the service menu)
  5. Sharpness
  6. Hue and Saturation (tint and color)
  7. Color decoder (requires use of the service menu)
  8. Repeat (6) and (7) for red and green until you have a good balance.
SERVICE MENUHow do I access the service menu?
In a word, don't. See the service menu warningabove. If you're bound and determined to make use of the service menu,buy the service manual. It contains more than enough information foryou to ruin your display and/or kill yourself.

Hi, I have just purchased the Samsung LE37A559 tv. I have been trying to get the best colour settings brightness colour contrast tint backlight etc. Is there a optimum setting for all of these ? I am...


The problem is that everyone has a different "taste" when it comes to these settings. I like to turn the color all the way down to start with. You should (if the set is factory adjusted correctly) have a black and white picture. If it's not B&W, then there's something inside the set that needs adjusted and you should get a service call. Then I adjust brightness and contrast to get the best B&W picture. Then I turn the color up until I'm happy with the color level, then I adust tint.

Hope that helps

Red , Green And Blue.


Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.

Color Problem after replaced Circut Board


When you replace the entire board in a Zenith TV, you must make the adjustments to align the new chassis with the old picture tube. You must adjust the CRT bias and drives as well as the horizontal and vertical parameters. On the older boards there were controls on the main and CRT boards but on the newer boards the adjustments are made with the remote control after entering the service mode. Tune in the shopping channel QVC, set the color and contrast to minimum and lower the brightness until the picture is just visible. Set the CRT bias settings for a pure black and white image, then increase the brightness and contrast to get a very bright picture and if necessary adjust the drive settings so that the bright picture is pure black and white. Return the video settings to normal and then adjust the vertical and horizontal settings so that the info boxes on QVC are centered top, left and bottom. If you are not sure that you can do that right then have a qualified tech handle it for you.
