I have microwave model fmv156dcg. After a period of time the digital display has become hard to read. If i squat down a bit and look up at an angle I can read the display but it's almost impossible to read looking straight at it. Is the display bad or is there an adjustment for the display. The physical orientation of the display has not changeds so it's an intesity setting or some other kind of problem. Thanks in advance.

If you have a smoker in the house, the display may be coated with tar from the smoke. Spray some window cleaner on a soft cloth or paper towel, and gently wipe off the display face (do not scrub; it scratches easily).

The power supply capacitor on the controller board may be going bad. Unplug the oven, remove the top/side cover, and inspect the electrolytic capacitors. The tops should be flat; if any are domed or obviously leaking, they should be replaced (note: sometimes the top of the capacitor has a thin plastic disc covering it; doming of the disc is normal). See the photo below to identify good and bad electrolytic capacitors. This photo is from a TV or computer power supply and your controller will not look this. You're looking for components like bad ones marked in the photo or the good ones next to it. If you see a bad capacitor, post a comment with the capacitance (e. g., 2200 uF) and voltage rating, and I'll recommend a part number that I know will be a good replacement. The cost is usually under $2 plus shipping from whatever supplier you choose.

It is possible that the display itself is going bad, but this is not very common.
