Last night we heard a pop sound in Kitchen, could not figure out but then saw no time was displayed in microwave, (Note Microwave was not being used at the time of POP)
Removed the plug and used other appliances to make sure outlet has power and everything worked, so we ruled out any trip or no power in the outlet.

Opened the Microwave and tested the power with meter and it is showing that power is coming.

Left the oven off plug overnight and tested again
and afterwhile plugged it again to see, if anything has changed but still not working.
Seems like there is no life on the control panel where all the keys are located.
We do not have any warranty and just bought in 2007, please help:(
