Hola Norman Malkin, para ajustar el brillo de tu TV Samsung, debe entrar en Menu, selecciona Imagen, de desplegara un listado donde te aparece Contraste Brillo Color y otros parametros, selecciona Brillo e incremente o disminuye el Brill hasta tu gusto, puede que necesites hacer ajustes de Color y Contraste
Espero lo puedas ajustar
Saludos Franco Dosil

Adjust the brightness until it starts making the black in the picture slightly milks and back it off slightly
Adjust the contrast so that the whitest whites show detail, too much contrast and they disappear
Adjust colour to suit, start with it half way, look at flesh tones on a news reader as a guide and adjust sharpness so you can see detail but not so that there are false or visible edges around things

old if it has a manual tuner there will be a fine tune adjustment.
It would be behind the channel selector knob or in some cases
very close. If the tv loses color try this first.
re-post if you need more info.

What about the TV reception? Is it alright?

This may help you...you can also get an owners manual free on line.

You really just keep moving between the Menu and arrow til you get it right.. I definitely needed to turn down the brightness on my monitor.

well it all depends on where the tv is located to, if it is in a room with little or no light( windows, lamps) you will want you brightness to be a lil lighter hince not makin the picture as dark, and vise versa for light rooms, u'll wanna turn the brightness down a lil bit to accomidate this room, as for the others i'd say a lil over 50% on them, thats how my office tv is set up, hope this helps, jason

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.

*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
