VFDs (vacuum fluorescent displays) are tricky, most likely you are looking at replacing the entire board. This contains the display and the entry key plus their logic. If you open it up check the connections for cold soldier joints, beyond that it's probably time for a new oven, much cheaper!

Interactive display on microwave


Is it the LCD display that you are speaking of? Is it full vertical or horizontal lines that are out, or only certain LCD segments of the numbers/letters?

The lcd display is not displaying properly at all and the light is no longer working. But its still heating! Could it be some sort of fuse?


It will be the display driver or illumination that has packed up. A replacement display panel is required.
Consult an authorised Microwave dealer for price and advice.

The display no longer works on my Model R303CW Sharp Microwave. Is there a part that will fix the display?? Everything else works fine.


Nope , could be dry joints or corroded pcb or defective display driver or supply ? Only can be told once opened and inspected.

The Display is Dim. Hard to read the numbers.


I have the same model and problem. The time display is totally unreadable. Looking for a solution as well. I suspect given the cost (I believe around $60), it's time for a new one. Anyone have any suggestions or easy repair ideas?
