YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

But here is a basic method if you are mechanically minded and have electrical safety knowledge.

The lamp is sat in a housing and its position is adjacent to the vent holes that it shines through.
If you feel confident, disconnect it from the mains power, remove anything in the cavity.
Remove the microwave cover. Purchasing a new replacement lamp will be useful as it will give you an idea of what it looks like. Locate the dead lamp remove the lamp and fit the new one. Replace the covers. Plug it back in and try the lamp by opening the door.
Hope this helps.

If you mean a loud buzz that cuts on and off as the oven works, it is probably the outer metal cover vibrating as the magnetron powers up and down. Try holding/ pushing/ poking the metal cover while the oven is working, if the noise abates or goes away, this is the problem.
You may get relief by simply tightening the screws securing the cover, if not, maybe a little careful insertion of a thin strip of cardboard or similar, at the point the vibration occurs, may dampen it. Good luck.

you have to replace the control board id use it long as i could then get a new one as microwaves are getting so cheap its cheaper to get a new one as it is to fix
