There is a internal locking mechanisim that has 2 or more switches that is usually attached with two or more screws next to the door latch side. Crack open the micro and adjust this by shutting the door then pushing this assy toward the latches untill all the switches look like they are being pushed in fully. If this doesn't solve the problem one of the switches or possibly more are defective. Call a local appliance repair center and get a switch there called micro switches.

After a bit of digging, it appears to be an issue with the door not being closed correctly (or at least the it thinks is isn't.
I know its a different model but the functionality is identical...

It's usually a broken tab on the upper switch holder, allowing the switch to rotate
just out of position.
This tab can be hard to see, since it is under the bottom edge of the switch.
While replacing the switch holder is the preferred solution, using hot glue to secure the switch to the holder is much easier and quicker. Just be sure not to let the door be slammed from now on.

I had this problem too:
it turns out that it (apparently) just needed some 'warm-up' time!
After being plugged in for about 15 to 30 minutes,
the buttons suddenly "came to life"...
Note that when it's flashing 88:88 you are supposed to _start_ with the 'Stop/Clear' button. After that, set the clock (press "Clock", enter the time with the number pad, then press Clock again).
Hope that helps.

When I opened up the microwave cover, noticed that the door latch mechanism was worn and not holding up the interlock switch. A thick piece of tape on the worn piece of plastic and microwave was back to working (I had symptom of the timer counting down without the microwave turning on)
