1. Kab mob degaussing txawv txav: cov duab xim tsis zoo lossis qee qhov chaw;
2. Tsis zoo li rectifier thiab lim Circuit Court: peb tsis muaj faults: lub peev xwm ntawm lub lim capacitor txo, uas yuav superimpose cuam tshuam rau cov duab thiab suab, thiab txawm ua puas lub hloov raj;
3. Cov zis hluav taws xob ntawm kev hloov oscillation thiab voltage stabilization yog qhov txawv txav: muaj lub suab "squeak" tom qab khau raj lossis lub suab degaussing ntawm "cha" tuaj yeem hnov qab tom qab booting, thiab peb lub tom ntej no tsis muaj;
4. Lub switching tube pib-up Circuit Court los yog lim capacitor muaj peev xwm ntawm lub sampling Circuit Court txo: peb tsis muaj faults;
5. Cov qauv ntsuas hluav taws xob tsis zoo: lub ntsiab hluav taws xob hluav taws xob nce randomly, tab sis kev tiv thaiv Circuit Court tsis zoo tag nrho lossis tsis ua haujlwm, tom qab ntawd cov duab dheev dhau los ua ci dua thiab xim yuav sib dua. siab;
