The screen control setting may need to be adjusted - the screen contol is a service adjustment and is located internal to the TV. If you turn the TV to a blank channel or video input with nothing connected is the prevailing color red? if so adjusting the screen control may help.You would have to take off the front panel and remove the covering- let me know if you want to go ahead and I'll guide you further - caution since high voltage is present in this area.

Why cant i change the tint of my picture? the menue keeps skipping the tint option


If you're watching UK TV broadcasts then we don't have a need for tint. Similarly, with HDMI sources you shouldn't need tint either because the TV's colour decoder isn't active.

Tint is a throw-back to the American analogue TV system called NTSC. Their system doesn't lock the colour phase to the sync signal. So depending how far the TV was from the transmitter the colour would be further and further out of whack. Hence the industry joke that NTSC stood for Never Twice (the) Same Colour ...N - T - S - C. The Tint control was used to re-time the colour signal. The UK didn't have this issue because our TV system (PAL - Phase Alternate Line) includes information to lock the colour signal phase.

Strictly speaking, Tint is only required with NTSC analogue composite signals. This is where the brightness information is mixed with colour on a sub-carrier frequency. So, that would be signals via an aerial lead or from the yellow video connection which is how most of us first see a composite signal. These signals are encoded as NTSC. Any signals where the colour and brightness (luma) information is kept separate shouldn't need Tint. So, S-video, Component and RGB at 60Hz all bypass a TVs NTSC decoder. If the TV is correctly designed then the Tint option should not be available. Some TV manufacturers break the convention though, for the simple reason that many old school US consumers grew up adjusting Tint, so it's too much of a culture shock to take away that feature.

To recap then, if Tint isn't available then it's because the signal doesn't need that adjustment. The colour timing is already bang on accurate.

Theres no brightness setting in menu. it only has cc sleeptimer and exit. how do i change the brightness?


Hello
You can adjust the brightness control on your 19PR19 Philips Tv. For that you have to go to picture contol menu
Do it as follows

To adjust your TVs picture control, select a channel and follow these steps.

[1] Press the Menu Button on the remote control to display onscreen menu.
[2] Press Cursor up or Cursor Down button until the word Brightness is hilighted. For each press of Cursor Up or Cursor Down button you can go through Colour, Picture, Sharpness, Tint, Colour temp etc, depending on the adjustment you want to make.
[3] Press Cursor right or Cursor Left buttons to increase or decrese the selected option. Ok.

Some channels on my tv are dark and tinted orange, I used the menu button to display the menue and scrolled down to picture but I did not know how to select picture.


Hello
Adjust colour control to zero, and check for a pure black/white picture. Adjust contrast and brightness control to minimum and check whether the picture goes completly off or a slight picture prevails. If the picture goes out when you turn down brightness control to 1/3 position, that is about 20 points, your TVs screen voltage is very low, and it can be adjustable. If the picture does not go out and more brightness prevails, screen voltage is high. If the screen voltage is high, there will be some fine lines across the screen at about an inch apart; on the whole screen from top to bottom.
Screen voltage adjustment is critical for the clarity of the picture. If it is low, no proper colour will be dispayed. If it is high, it is harmful to both picture tube and your eyes.
Never try to adjust it without proper knowledge about it. The screen control can be located alongwith the LOT [Line Output Transformer], of your tv. There will have two adjustable controls there, one is for Focus, and the other is for Screen. Both are interactive, that is adjusting one will effect an other.

I replaced my convergence IC's and know my RED CRT is too bright.


Can you find the screen and focus block? There are six controls on it; three for focus and three for screen adjust ( brightness ).

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

Green tint I can't seem to fix


Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.


By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.

it depends on what your using it for, adjust colour tones to what you think looks natural, contrast between 80-90, keep sharpness below 30. just have a play around till you find what best suits the source material.

Roger, if your contrast (sometimes called picture) and brightness controls are at max you can increase the tubes brightness by turning the "screen control" clockwise, be advised a little turn goes a long ways, don`t crank it too far or you will get retrace lines, you will have to remove the back from the set and follow the red wire down from the tube to the "flyback transformer" on the front of the flyback are 2 controls, focus and screen, do not move the focus control, this should fix your problem.
