Small circle indent? Maybe you should elaborate. If you're talking about the sensor, the best thing to do is check the troubleshooting guide that comes with the system (I believe it's in the operating manual). I've found that if you have an open window in front of the TV (facing you), that it disrupts the signal. Also, if you have alot of wireless computer peripherals, i've heard that they may or may not have an effect. Like I said, check the troubleshooting guide.
I have been having some problems with my wii. It has been making a small circle indent on almost all of my games. So i sent it in to get repaired. I get it back and its still doing it. I just want to know if its happening to any other of u guys. If you fixed the problem tell me how.
