When i start my tv, a reddish color appears and then after two to three seconds, it comes to normal. However, even after two to three seconds the brightness of the tv never comes to normal and it is slightly on higher side in terms of contrast. This causes the sharpness and brightness problems specially during the scenes of sunlight.

My first concern would be that, the picture tube is going bad. The problem you describe, tell me one of the color guns is shorting. In this case I would think the green gun is shorting. There are three color guns in the neck of the picture tube. They are red, green, and blue. Most of the time the green will short as it is powered heavily in most TVs. The next thing to check, is the small board connected to the picture tube. Look for any and all bad grounds on this CRT board. This is another big problem in all Tube type TVs. On this small board there will be three color output transistors, and resistors. These will many times run very hot and will create bad grounds over time. Check and resolder as necessary. If the CRT board does not fix your problem, replace the TV. Picture tubes are very expensive and will not be feasible for replacement. Search for a new TV. Thanks for asking and show all hands of support!

assuming you gave checked the menu settings for the video out, I would say your plasma panel board may need to be replaced

Had similar problem. Thought it was the lamp. Examined old lamp but it appeared to be good. Ordered a new one anyway. Changed the lamp but the TV screen would not come on. It would make the usual noise as it was going to come on normally but it would cycle 3 times & then turn off. The LED lights in the front panel would indicate a defective lamp. Then read about the ballast. Changed the ballast & still same problem. Tried starting the TV without the lamp installed & noticed that the color wheel did not spin. Removed old color wheel & discovered it was broken. This appears to be the cause of all of my problems. I wish I new earlier of the test-turn on the TV without the lamp being installed & check to see if the color wheel is spinning. Would have save money on the lamp & ballast.

Depending on your TV, you may have a Color Temperature (Color Temp) and/or Hue setting in the menu. Use these options to adjust the picture to the setting that best suits your viewing preference.
If your TV has a Color Temp setting, you will normally have the following options to select from:

• Cool: Gives the picture a cooler, slightly bluish appearance.
• Neutral: Gives the picture a neutral, more natural look and appearance.
• Warm: Gives the picture a warmer, slightly reddish appearance.

If your TV has a Hue setting, follow the appropriate step below to make adjustments:

1. Move the setting to the right to reduce the reddish appearance.
2. Move the setting to the left to reduce the greenish appearance.

Here is a link from Microsoft to check...

However, the 3 red lights usually means the console needs to be sent to microsoft for repair. For this they will normally repair for free. Go to this website and follow directions.

Although normal room lights (tungsten lights) appear white to our eyes, their light is actually much "warmer" than daylight, giving a reddish or orange color to pictures. This happens with digital and film cameras. To prevent or lessen this reddish or orange color: If your digital camera has a selectable White Balance mode (check your camera's User's Guide) and you are not using the camera or external flash, set the White Balance mode for "Tungsten" light. If your pictures are reddish even when you use the camera flash or external flash, the room lighting is overpowering the flash. Try setting the White Balance mode for "Tungsten" and continue to use the flash. If your camera does not have a selectable White Balance mode, use the camera flash or external flash when taking pictures in lighting that makes your pictures turn out reddish or orange. If you can, turn down or turn off one of the room lights (without making the room too dark), or move your subject so that it is not being hit directly by the room lights. If you can, when taking pictures in the daytime, try opening any drapes that might be covering windows. Letting in natural daylight improves the color quality of the lighting.
