The sound is normal, the picture is milky looking and negative looking at normal brightness and contrast settings. There are no visable lines on the screen. The menu is equally bad as the video. I suspect the main board or T-con board,power supply caps look normal. Thanks!

A lot of people don't realize that backlight settings can affect the picture.
Go to the menu (press menu on your remote)
The menu will show picture options. Just toy with different settings until you find what you want. It may be on a preset setting that doesn't work. If you are in a bright room, you will need to increase brightness and contrast and perhaps backlight.
Usually an unclear picture is due to the contrast, backlight, and brightness settings being too low. You can also increase sharpness.
I suggest a contrast setting of 70, a brightness setting of 60-80, and a backlight setting of above 80.
1.Turn on the LED TV and let it warm up for 30 to 40 minutes before making any changes or adjustments. 2. Put on the lights that you would normally use when watching the TV. You want to create the same ambiance that would constitute normal watching conditions for you. Make sure there is no glare or reflection from other items in the room such as a mirror. 3.Open the menu on the screen of the LED TV with your remote control and find the options for adjusting the color, contrast and brightness. Menu options will vary by TV, but look for options that will say "Contrast," "Color" and "Brightness." 4.Start with the "Brightness" control. It would be best to have a DVD playing so that you can get a better idea of the control settings. Pause the picture at a place that you can see a variety of scenery, such as sky, mountains and people in the forefront. Adjust the "Brightness" by pressing the up and down arrows until you are happy with the picture. Press "Save" or "OK" to set the brightness at this level. 5.Repeat this with the "Contrast" and "Color" controls, remembering to save your settings. Look for the "Mode" setting. Press the arrow to get to "Normal" or "Movie/Cinema." Press that setting and save it.6.Turn off any settings that are titled "Flesh Tone Correction" or "Vivid Sports." These will make the colors unnatural, use up energy and damage the TV over time.
Since you have replaced the Color Wheel, it sounds like you have not adjusted the Index Delay in the service menu. First reset all of the picture settings you have adjusted back to original factory settings. Then on your Samsung TV Remote and with the TV OFF, Press Mute,Power,123. This will turn on the set and put you in the Service menu. Look for the top setting and select or scroll to the OPTION setting and select and look for INDEX DELAY and select that. Once you have the Index Delay selected use the right and left buttons on the remote to adjust for a picture the has no abnormal coloring and while looking at a program adjust for when the blacks look black with no abnormal coloring. Once that is done, turn off the set then turn the set back on. Now the picture should look normal.
if the picture is REALLY dark, like you can just barely see it in a lit room, then the backlight might not be lit. LCD TVshave backlight that shines through the LCD screen which allows you to see the picture.
If it's not the backlight then it would be the brightness/contrast settings that need to be adjusted. If the picture used to be normal and all of a sudden went dark, verify the backlight. Normally you can look through the slots on the top of the set and determine if the backlight is on. If you can see a bright light through any of the slots, the backlight is probably OK... go after the brightness/contrast settings.
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.
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.
When you replaced the flyback the new flyback is shipped with the screen and focus controls set at minimum. These are the 2 controls on the flyback itself. Turn the set on and let it warm up a minute, then slowly turn up the screen (bottom) control with a small flat-head screwdriver. When the picture is around normal brightness, adjust the focus (top) control until the picture is nice and sharp. Then, turn the brightness and contrast all the way down and set the screen control until you can just see the picture, just above the point where the picture vanishes. Reset the brightness and contrast settings and your picture will be back to perfect.
*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.
