Hi, I need a help on my Samsung DLP 61" HLR6167W. After replacing a digital board by the Circuit city technician, the picture quality on my TV has been distroyed. There are lots of visible pixels and the picture is not as sharp and crisp as it used to be. I called Circuit City customer support again and the same technician showed up again. This time he went into the Service Mode and changed the default factory settings without having any clue of those settings. Now my TV is even worst than it used to be. Is any one can help me to find the original Service Mode factory settings for my TV. Is there any way to revert these settings back? Also, where can I get a service manual for this model?
