Impamvu nyamukuru nuko hariho igishushanyo kumurongo wa firime cyangwa kuzibira kuri ecran yatwikiriwe, kandi umuringa ugaragara kumwanya uhamye wurwego rushyizweho na anti-plate utera PCB kumuzunguruko mugufi.
Kunoza uburyo:
1. Ibibi bya firime ntibigomba kugira trachoma, ibishushanyo, nibindi. Ubuso bwa firime yibiyobyabwenge bigomba kuba byerekeje hejuru iyo bishyizwe, kandi ntibigomba gukubitwa nibindi bintu. Filime igomba gukorerwa ireba hejuru ya firime mugihe wandukuye. Bika mu gikapu cya firime.
2. Iyo uhuza, firime yibiyobyabwenge ireba ikibaho cya PCB. Mugihe ufata firime, koresha amaboko yawe kugirango uyatware cyane. Ntukore ku bindi bintu kugirango wirinde gushushanya hejuru ya firime. Iyo buri firime ihujwe numubare runaka, ugomba guhagarika guhuza. Reba cyangwa uyisimbuze numuntu udasanzwe, hanyuma uyishyire mumufuka wa firime ukwiye nyuma yo kuyikoresha.
3. Umukoresha ntagomba kwambara ibintu byose bishushanya nk'impeta, ibikomo, n'ibindi. Imisumari igomba gutemwa kandi igakomeza kugenda neza, nta myanda igomba gushyirwa hejuru yimeza, kandi hejuru yimeza igomba kuba ifite isuku kandi yoroshye.
4. Mugaragaza igomba kugenzurwa cyane mbere yumusaruro, kugirango urebe ko ecran idafunzwe. Iyo ukoresheje firime itose, akenshi birakenewe gukora ubugenzuzi butunguranye kugirango harebwe niba hari imyanda ibuza ecran. Mugihe nta icapiro ryigihe runaka, ecran yubusa igomba gucapurwa inshuro nyinshi mbere yo kuyisohora, kugirango inanasi muri wino ishobora gushonga burundu wino ikomeye kugirango hamenyekane neza ecran.
