I have the reoar seat enterntainment package (RSE) and my rear console no longer works, im assuming some how my Parental control button was activated, but i dont have a clue where it is or how to enable or disable it..btw this is on a 2004 tahoe.

do you mean the panasonic DVD system? The parental control button is located right at the front of the dvd player, within arms reach of the driver.

On an '04 RSE, the screen says ' Parental Control ON' when it's active. Does the screen say anything?
