My TV is a 52HMX84 which is 52 inches but shares the same features as the 62 in TV. Starting a few months ago, I notice that some visible color bands are moving slowly up the TV at all times. I have tried all types of adjustments in temperature, color, brightness etc., but I can not remove them. This problem is present whether I am using HD cable, playing DVD or playing PS3 games.
The bands are caused by unsheilded power cables that are near the set. sometimes your tv cable or antenae cable is near a power source and it is picking up unsheilded EM signals. Remove all power sources near your tv and tv cable.

The tv lamp was replaced when? The tv on about 4 or 5 hours a day right?The lamp was replaced about a year or a year an a half ago?The projection lamp is dead,the life span is over.Must replaced with a new lamp.
If you are connected to a cable box, first disconnect that and then watch another source. If the band goes away, the issue is with the cable box or the input line has a bad ground and time to notify the cable company. If it is still there, you might have a bad capacitor on the power supply board inside the TV. I feel however the cable will be the issue...Please take a few minutes to rate my answer...Thanks
the reflecting mirror is likely loose and falling down inside the light reflecting tube. you should have seen the band getting darker and larger, the small mirror is in front of the lamp and bends the light, remove the lamp and look down the tube (light path)
Did you get this problem resoslved? I had the same issue a few months ago. I tech came by and took my TV to the shop, a few days later he said it was fixed as they needed to make some adjustments.....The TV has been fine up until a week or so ago and now the red dots have appeared again. Was wondering what happened to yours.
