Hluav taws kub ceev teeb ceev zog mov
Jul 28, 2015

1. siv ib resonant capacitor C6 lawm (Circuit Court luv) los yog siab kom txhob muaj (ces mos), yuav tsum muab hloov los ntawm siab saum 1kV thiab lub ntim zoo polyester los yog CBB capacitor.

2. qhib lub teeb ntsiabteeb. Yog lub teeb tsis tau ib tug dub loj teeb taw lawm nyob rau thaum uas tig mus 0. 047 μ F/400V polyester capacitor kev.

3. qhib Circuit Court los yog los pauv qhov nqi ntawm R1, R2 (R1 failures ntau dua), tus muab ntawm 1/4W zoo thiab kuj tau nrog tus ua hauj.

4. transistor qhib Circuit Court. Tsuas yog ib tug transistor opens, tab sis tsis tau hloov tau ib tug xwb, mas yuav tsum hloov txhua voltage 400V los yog ntau dua ntawm tib hom paired keyboards. Nws tsis ntog teeb pom kev zoo los hlawv raj dua.

5. teeb nyem. Teeb ib tug dub loj, tsis tau xyuas seb cov D5, D6, txias ham ob leeg los qhib, yog D5, D6 mos mos lawm los yog phem lim capacitor muaj C1 to thiab yuav tau muab teeb nyem.

6. teeb kom sib, kov teeb tej zaum yuav pom pom los dov, yuav tsis txaus tau txog C3, C4, tsis txuam.

7. yog ib zaug xwb qes zog zog txuag roj taws teeb liab los sis ci phenomenon, koj yuav tsum tau kos lub D1 ~ D4 mos, tsis muaj C1 yog ntsia rov mus, los yog to, hwj huam mov luv Circuit Court.
