SOURCE: Dark screen/picture.

This 30" flat screen TV set may have a problem in the high voltage circuit of the TV set. You may be able to adjust this by taking off the back of the TV set. Look for the block where the large red wire runs up to the top of the picture tube. On this block will be two controls. one will say screen and one will say focus. Try and slowly turn the control that says screen or S on it clockwise and see if you can make the picture brighter. Turn up the control till you just start to see faint lines in the picture, then back the control down till the lines go away. If the picture does not come up when you turn this up, and all you get is a blank screen, you will need to have this set repaired by a qualified repair person. Good Luck

dear mr faolib
the solution is to install a 250 ohm resistor between G1 and ground on the socket ,,,but you may change it more or less than 250 ohm . it well be lighter and you you can adjusted normally from controll panel

SOURCE: Brightness keeps shifting on Samsung 46" 7 Series 750

I just purchased Samsung series 4 LCD TV yesterday. I had the same problem since my salesman was a kind of stupid. He set the 'Power save mode' to automatic. After fiddle with my TV for a while, I found the solution.
Just change the 'Power save mode' to off, low, normal or high. My LCD TV stopped shifting its brightness.

Why does my sanyo dp46848 screen go dark but whites are too bright?


First try to gently push the cable between the main board and the LCD controller (T-CON) board and if that doesn't affect the image then replace the T-con board.

Dark picture,can't get it to brighten up with menu color settings.


Assuming brightness and contrast (picture on some sets) does not help it could be a number of things, how old is this set?

Television comes on and then screen goes very dark. We have been able to check the menu contrast, tint, brightness, etc, but nothing helps. What do we do now?


most likely a defective Z-SUSTAIN board failure if the video looks somewhat correct and the tv is just dark. the Z-SUSTAIN board basically powers the plasma panel and if it fails a certain way it will cause this problem with the dark video. if you can get the tv taken apart and look for part numbers off of the board on the far right looking from that back then you may be able to find the part on the internet somewhere otherwise Contact Sanyo Manufacturing Corp 1-800-877-5032. good luck

What is the best picture settings ,like color,tent ,contrast,brightness..ect..


Just a suggestion, since you gave no model information, no specific directions can be given. <div><br /></div> <div>If your set, through the main menu, offers the choices of 'Warm' and 'Cool,' try both to see which you like better.</div> <div><br /></div> <div>The first offers more intense colors, the second (which we prefer) is much more natural to our eyes with flesh tones and single colors closer to nature.</div> <div><br /></div> <div>If you don't have those choices, try varying the color intensity first, and tint second since the last one is pretty easy to find one that looks more like life.</div> <div><br /></div> <div>Brightness and contrast are highly dependent on the viewing room so there isn't really a 'right' or 'wrong' setting for this.</div>

Cannot adjust color


Have you turned the controls from one of the presets? Presets are Vivid, Movie, etc. Most sets have to be in Custom or Customize to adjust the controls, likely on-screen with one of contrast, brightness, color, or tint selected. If those are horizontal bars then up/down selects which and right/left select decrease/increase or red/green for tint. Start with 50% if no reset (0% for R/G) or start with the non-Vivid settings. Consult AVS forums for you model to get better settings. Rules of thumb: Brightness should be as dark as possible without losing gray scale at lowest part. Contrast should not be so high that whites bloom or make it hard to see. Color should not blow out any color nor be unnatural. Tint is best judged on flesh tones. -Ken

Well i really want to know what level the coular and brightness lvel has to be on a toshiba t.v


You can set these controls to your liking, though a lower brightness setting might increase the life of the screen. First, set the brightness and contrast to a level that is pleasing to the eyes, then adjust the color to look realistic - enough color without being disturbing. If faces area look greenish or purplish, then also adjust the tint (sometimes called Hue) until you get accurate flesh tone. Flesh tone is the best thing to adjust for; when you get good flesh tone, the rest of the picture will look great. ALWAYS make adjustments during a live news broadcast, which tends to have the most accurate balance of brightness, contrast, color level and hue. Note that commercials are all recorded in different studios with different settings, and will usually not look right - it's best to just live with this than to constantly readjust the TV. There are also DVD's available which walk you through proper TV adjustment.

Did you goto the MENU to access the different controls ?
Brightness, contrast, color, tint hue ??
There is always a way without the remote control [R/C] to get at these controls.
