Does your stereo have a childs lock? If it does; why? Anyway the cd open button could be defected. Possibily a loose connection on the cd open switch on the inside of the unit. Also dose the remote have this function? Check the battery. Clean the remote sensor on the front of the remote and on the stereo.
Hope this helps.

SOURCE: TV will not power on
The MZ73L is a posistor, its basically 2 thermal resistors back to back. One is connected across the mains, the other one connects the deguassing loop to the mains. When the TV is 1st turned on the mains connected R is cold so its neighbour is cold, that allows a large surge of current into the degaussing coil. The mains connected one rapidly gets hot and heats up the other one, this increases the resistance of it and the current being dumped into the degauss coil fades away. As the 1st one is a heater it will get hot and you will see signs of heat on the PCB, BUT its still a very good place to start. The heat is normal, but if the 1st ceramic disk in it has died then you will short the mains and blow the fuse with it.
