The LCD on my Sharp microwave oven recently failed, outset with a few segments simply apace getting worse. I've seen quite a few similar models with the same trouble and a quick Google search proves this. Precipitous even offered a recall at 1 stage.

If your microwave oven suffers a similar fate and you could give this a endeavor. Note that it is not actually an LED brandish as some seem to think; Abrupt have simply done a pretty convincing job of making the LCD await like one.

First up, merely open your microwave if you take experience working with electrical devices. Microwaves operate using very high voltages that can remain stored in a capacitor even after switching the unit off.

Disconnect the microwave from the supply and remove the cover. Practise non touch on the magnetron, transformer or capacitor.

Take a note of all the connections to the power supply PCB on the rear side of the front panel. Disconnect all of the wires.

The front panel is held on by a single screw near the top. One time this is removed, open the oven door and slide the panel upwards to remove it.

The LCD is mounted on the dorsum of the controller PCB and connected via a ribbon cable. This cablevision is attached using what appears to exist conductive gum. I gauge this glue breaks downwardly over fourth dimension causing dodgy connections to the LCD.

I was able to mostly fix the display in my microwave only by running a hot soldering iron across the black glue. This may work for you lot. Information technology volition probably require some trial and fault until the display works. Simply don't connect the microwave to the mains supply with the encompass removed!

I decided to scrape all of the black mucilage off and repair each joint using a conductive pen. As the pen is quite clumsy (it'south basically correction fluid with silver instead of white pigment) I establish it easier to draw a continuous line across the contacts, so advisedly scrape away the excess betwixt each pin. After I covered it with a strip of hot glue for protection.

While non particularly elegant this has stock-still the brandish completely!
