Thank you for the info, Janice.
Before doing anything else, lets try a system reset:
1) Unplug the power cord from the outlet
2) Wait at least 1 hour (60+ Minutes)
3) Press and hold the power button (on the set, not the remote) for 60 seconds
4) Keep holding power button while plugging back in, and for another 60 seconds after. When plugging back in, go directly to the wall outlet, bypassing any power strips or surge protectors.
If this reset process does not work, it would unfortunately confirm a hardware fault, which could be the internal sensor, but is more likely a faulty remote.
You have 2 options here.
You can buy another remote, but they are really only available used: http://www.ebay.com/itm/like/371584636192?lpid=82&chn=ps&ul_noapp=true
Or, since it is less than a year old and under warranty, you can call sanyo to file a warranty claim and ask them to replace it for you.
Getting a new remote would be faster, but you may be better off calling them anyway, because they would hopefully replace the entire system, in case this is a fault with the internal sensor on the main unit. If you want to reach out to them, you can do so at(###) ###-####/p>
