Question about Sharp R-1750 Microwave Oven

2 Answers

Sharp R-1750 I have my Sharp R-1750 microwave for 6 years. Recently the screen stopped working. All symbols gradually disappear and then after a while (a couple of days) it goes to a blank screen. The microwave still works but the screen does not. When I unplug and then plug the microwave back in, the screen works and then soon stops working again. Thank you very much for your solution.

    I have the same problem. I took it apart and it seems to be a loose connection between the lcd panel circuit and an intermediate side mounted board. It is a very thin ribbon cable black on one side and with white on the other w/ adhesive connections on the ends. I wiggled the bottom end of the cable and the lcd came back for brief moments. This has to be an easy fix or people would not do it for $39 including shipping.

    Here are some pictures of the faulty ribbon cable.

R9H84B Sharp Microwave Convection from 6-6-1997, power stopped and turntable stopped. Light works and sounds like the power is working but nothing gets hot.


Is this the unit with the door that swings down like a conventional oven?? I think it is. This sounds like a door switch but could be a magnetron or cook relay on the control PCB.
