I have ne 9870 micowave. Its part of touch pad was not working so,I had to give it to some local repair shop.He disconnected all the wire & could not fit it. I had given to another National repair shop & he repaired the touch pad but could not join the wire for use. He informed if circuit detailds they got then only it can be done fully. Do you have maual with circuit details. Kindly help. Diapk Biswas dipak.biswas@ptg.contitech.in
