Question about Standard (CRT) Televisions

1 Answer

Picture is very dim

This set was manufactured in 1998. The picture is dark using the factory settings. I increased the brightness, contrast, picture setting to the max and it is viewable, but still dim and flickers when viewing a program with a bright white background.

There is a problem in the flyback section of the tv set. the fly back has two knobs, one for screen and the other for focus. use the screen knob to adjust the brighness. if it did not help, either check the capacitors around the flyback or change the fly back with a new one. good luck

The best contrast and brightness settings for a toshiba crt floor model tv,model 50A61


Televisions are unlike other consumer electronics products. Their setup and settings have a tremendous effect on how well they perform. The best TV on the market incorrectly setup will almost always look worse than a mediocre TV setup well.
Ideally, you'll get a setup disc to ensure the correct settings, but regardless, it's important to know what each setting actually does.
To get the ultimate performance out of your TV, a full calibration by an ISF Certified technician is your best option. Even if you go that route, it's good to know what the calibrator is adjusting. So here's a quick look at the basic settings every TV has, and what they do.
Please keep in mind, this is only a general guide in what each setting does, and rough idea how to set it. Correctly setting up a television is a completely different article.
Where to start
Nearly all modern TVs have picture modes. These are labeled things like Standard, Cinema, Vivid, and so on. Cinema or Movie is often the most accurate setting, with all the controls set to offer an image close to what a director intended them to look like. Most people aren't used to an accurate image like this, and to them the TV may appear reddish, soft, and possibly dim. Technically, it isn't. Other picture modes like Vivid or Dynamic are programmed to "pop" on a store sales floor with an overenhanced, blue image. Because most people don't change any of their TV's settings, this has resulted in most people thinking a TV should look blue.
The choice is yours, of course, but we here prefer an accurate image and suggest you at least try it for a few days. Once you get used to it, you'll never go back. Check out What's the best picture mode? for more info.
Regardless, all TVs need tweaking to look their best. Here's what the main controls do.
Backlight
Only LCDs have this control (though not all of them). This is a direct control of how bright the image is. Setting this lower will reduce eyestrain, and save a little on electricity. Before you adjust Contrast to make the image brighter, try here first. Check out LED LCD backlights explained for more on this.
Some plasmas have a control that drives the pixels harder, which in some ways acts similar to a backlight control. Samsung's name for this on their plasmas is Cell Light.
Contrast
Sometimes labeled "Picture." This control makes the image brighter...up to a point. Every television has a maximum light output. Once you reach this point, increasing the Contrast control further actually degrades the image. Correctly set, you would see a fluffy cloud in a bright sky. Set too high, you'd see a blotch of white instead. As mentioned above, try setting the overall light output of an LCD with the Backlight control first (if available). Then adjust the Contrast.
Brightness
This controls how dark the dark areas of the image are, again, to a point. Every TV has a minimum light output. Once you reach this point, decreasing the Brightness control starts removing "shadow detail." Correctly set, you'd see all the detail in a black leather jacket at night. Set too low, and it would be a black area on a black area, probably with a head sticking out of it. For more information on how the contrast, brightness and backlight settings interact, check out my article on contrast ratio.
Color
Can be thought of as color saturation. Setting this too high will make everything look cartoony. Setting it too low will make for an expensive black-and-white HDTV.
Tint
Rarely will you need to adjust tint, a vestigial control left over from the CRT "tube" TV days. It gives a green or magenta shade to the image.

I am trying to adjust the brightness on this circa 1980 floor model solid state tv


The contrast setting controls the relation between the light and black areas of the screen. If the light areas are too bright and are losing details, press the CVOL button; if the picture is gray and lacks contrast, press the VOLB button

The brightness setting controls the overall amount of light in the picture. If the picture is too bright, press the CVOL button; if the picture is too dark, press the VOL B button

The color setting controls the intensity of color.

I have a panasonic television that is very dark, the other colors are okay but when it goes to nights scenes, its very dark can this be repaired, the model number is ct-25G6E


It sounds like the master contrast has slipped. If you are confident with electronics, there is a little knob on the main board which allows you to set the master contrast. This is only applicable if the picture looks like it has too much brightness (like a white haze over the picture in dark scenes). Gently adjust the knob to set the correct contrast and you should be up and running. If that doesn't work, then your tube is on the way out.

Brightness of picture


If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.

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
