Not sure if you have fixed this, but you have two holes, one where the Blu-ray player is and another in the left wall where the TV slides down. Access both holes by taking the drawers out below the Blu-ray. If you pull the drawers out until they stop, you will see that there is a black plastic "finger" in the track. One side you push up, the other side you push down, this releases the drawer so you can completely pull it off the tracks. Take out one or more drawers to make this an easy job. To put the drawers back into the track, put the fixed portion of the track on the drawer into the part mounted. Once aligned, simply push it all the way in, the catches will pop right into place on their own, all back to normal!
