This is no solution but a point in a probable direction.
A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

SOURCE: Hi, I have just purchased the
The problem is that everyone has a different "taste" when it comes to these settings. I like to turn the color all the way down to start with. You should (if the set is factory adjusted correctly) have a black and white picture. If it's not B&W, then there's something inside the set that needs adjusted and you should get a service call. Then I adjust brightness and contrast to get the best B&W picture. Then I turn the color up until I'm happy with the color level, then I adust tint.
Hope that helps

This brightness irregularity is caused by poor voltage control in the horizontal scanning circuits. Voltage drops of this kind are usually due to aging electrolytic capacitors which lose the ability to maintain high voltage. This problem can be repaired but you cannot do it yourself. This type of TV can have DANGEROUS high voltages present inside even after it has been turned off for WEEKS. I'm talking HEART ATTACK voltages. Call a qualified service technician.

Usually factory defaults are set to the middle settings in your menu structure. If you have values then it would be the middle of the value.
Is there any certain reason why you wish to go into the service menus?
