I came home from college and I brought my microwave back and when I tried to plug it in at home it didn't work. The display screen lights up, but no numbers come on, and when I press the buttons on the keypad theres is no response from the microwave. The light bulb turns on when I open the door, and when I unplug it and plug it back in it makes a beep, but thats about it. What can be wrong with it?

Re:
It may be in child lock mode. Your owner's manual will cover that.
On the Sanyo EM-S5595, for example, you turn the child lock off and on by pressing and holding the STOP/CLEAR pad for 3 seconds. Yours may be the same.
You may also have a bad keypad, which in many cases can be replaced.
A bad keypad may be worn out due to age, may be damaged, or it may have gotten wet or otherwise contaminated.
Moisture and contamination can be caused by not using the fan when boiling on the stove top, direct spraying of cleaners, by storing the microwave in an unheated garage or shed, or by infestation.
I warn my customers to never spray cleaner directly onto the microwave keypad, since the liquid can get inside and "lock up" or even ruin the keypad or controller.
Instead apply an alcohol-based cleaner (such as the purple kind) to a cloth (since paper towels can scratch) and gently wipe it off.
I suggest to my customers that they NEVER use any ammonia-based cleaner (like the blue stuff) on a microwave, since the ammonia will crack and distort polycarbonate plastics.

The Keypad is either faulty, or disconnected. Open the case, and remove the screws, holding the outer shell on. Inside, there should be a small board that covers the Keypad. Check to see if there is a ribbon cable, or some other type of connection going from the board to another part of the microwave. If all of the wires are connected, then you will probably need to replace the keypad.
I would contact Samsung, they seem to be aware of the issue with the control panel failing on there otr model and are replacing them free of charge under there "epidemic warranty"
Check the power supply. Make sure the microwave is firmly plugged into a working electrical outlet and that your wall outlet is active if your home uses outlets controlled by a wall switch. Check your home's fuses or circuit breakers to ensure they have not been tripped. Without power the microwave will not respond to any input.
Make sure the parental lock is inactive. Some ovens, like the one shown in the image above, feature a keypad lock to prevent children playing with the controls. Most keypad locks can be cancelled by holding down a button or combination of buttons for a few seconds.
Make sure the door is firmly closed. Some microwave ovens will not allow any control panel input if the door is open.
Remove the microwave from the power, wait 10 seconds, then plug it back in. This will reset the microwave oven if there is a temporary problem with the software.
Press the "Stop/Cancel" button several times to cancel the current operation and return the microwave to standby mode. Re-enter your cooking instructions using the keypad as usual.
The solution is to troubleshoot the microwave as explained below.
1 Check the power supply. Make sure the microwave is firmly plugged into a working electrical outlet and that your wall outlet is active if your home uses outlets controlled by a wall switch. Check your home's fuses or circuit breakers to ensure they have not been tripped. Without power the microwave will not respond to any input.
2 Make sure the parental lock is inactive. Some ovens, like the one shown in the image above, feature a keypad lock to prevent children playing with the controls. Most keypad locks can be cancelled by holding down a button or combination of buttons for a few seconds.
3 Make sure the door is firmly closed. Some microwave ovens will not allow any control panel input if the door is open.
4 Remove the microwave from the power, wait 10 seconds, then plug it back in. This will reset the microwave oven if there is a temporary problem with the software.
5 Press the "Stop/Cancel" button several times to cancel the current operation and return the microwave to standby mode. Re-enter your cooking instructions using the keypad as usual.

you can try removing the outer cover and being careful,check all ribbon cables to the keypad by removing if they are plugged in and not soldered to the keypad circuit board and re plugging them back in,if this doesnt solve the problem you will need to replace the keypad board
I don't have Magic chef, however, I would try hitting cancel, unplugging the microwave and waiting a few minutes, then plugging it back in to reset it. Alternatively, you could go to your manual under troubleshoooting. I wish that I could help you more with this. Good luck to you. Please let me know if you figure this one out.
