I have a 900 MHZ Fisher Price baby monitor and have used it for over a year everynight. Last night it started being super staticy all night long. It is designed to light up when there is sound by the transmitter but now it lights up when there is static so I can't even turn the volume down. I can't hear my baby at night and have this on or I would not get an ounce of sleep! Is there something I can do to correct this? I tried to change the channel... switch receivers. Turn off transmitter for a while. Nothing worked! Help
