Keypad Problems Could not find any information regarding Samsung Microwave MW4552W; 2007 model. When one powers the microwave on, the LCD pad lights up with all green characters and the keypad does absolutely nothing. It looks like as if something tilted it. Reminds me of the movie ''The Matrix'' but without the characters moving up or down. Tried a ''hard reset'' and nada. Is there a way to reset the keybad. Perhaps pressing 2 or 3 special buttons at the same time? Someone please help me. Thanks! Robert

The microwave has a two door switch. I removed the microwave case and took an inside look as to check if anything is out of the ordinary. The keypad's circuitboard looks fine; all transistors look in place. I forgot to mention earlier when describing what appeared on the keypad. Where the clock displays, it looks as if it has digits of "8" across the board (looks like five "8's"). Under the first "8" it says "Auto Start". Under second "8" it says "LBS" and "DEF". Under the third "8" its says HOLD" and "TIME". Under the fourth "8" it says "SENSOR" and "BROWN". Under the last eight it says "TEMP" and "COOK". To the top far right it says number 18 and underneath it says "POWER". Under "POWER" it says "OZ" and next to it "SL" and underneath roman numeral number III.

So every function lights up like a christmas tree! If I open the door and then close it, I notice the fan moving a little bit. To see if I can "reset" the keypad, I disconnected the majority of the cables, put them back in place, turned on the microwave but still gave me the same problem.

I can't seem to find any forum, any user guide for this model. More help please....

Thanks!
