Yuav luag txhua tus neeg nyob hauv lub ntiaj teb no nyiam txoj yeeb yaj kiab, TV series lossis movie. Ntau npaum li peb xav tau, tej zaum qhov chaw saib TV poob. Nws feem ntau tshwm sim hais tias TVs nrog cathode ray tube (CRT) pib hloov xim hauv daim duab: koj lub TV yuav muaj kab ntsuab lossis xim liab nyob ib ncig ntawm cov npoo ntawm daim duab. Kev qhaj lub TV TV yuav pab tau kom tshem ntawm qhov tsis zoo ntawd.
Nws yog qhov tsim nyog
Ib qho khoom siv tshwj xeeb (txhawm chim) rau demagnetizing duab hlab
Cov Lus Qhia
Kauj ruam 1
Raws li txoj cai, nws yog qhov muaj peev xwm txiav txim siab lub qhov tsis ua haujlwm ntawm tus saib, uas yog, txhawm rau txhawm rau pom qhov tsos ntawm kab txaij ntsuab txhua hnub. Muaj ob qho laj thawj:
- lub tshuab tsom kab hluav taws xob (TV kinescope);
- kev hloov ntawm daim duab raj ua daim npog.
Kauj ruam 2
Lub tshuab hluav taws xob nyob hauv TV tau tshwm sim vim qhov tseeb tias tej zaum yuav muaj cov khoom siv hluav taws xob nyob ze TV, uas muaj lawv lub zog sib nqus. Lub counteraction ntawm cov rog no ua rau muaj hlau nplaum. Yog tias koj them sai sai rau qee cov khoom siv hluav taws xob hauv tsev muag khoom, tom qab ntawd cov khoom tiv thaiv kev tiv thaiv (hom kev tiv thaiv) yog qhia hauv phau ntawv qhia lossis tus nqi muag. Rau ntau cov qauv ntawm cov khoom siv audio, qhov kev xaiv no yog qhov yuav tsum tau ua. Piv txwv li, cov lus tshaj tawm rau lub khoos phis tawm, uas tsis muaj kev thaiv kab lus rau cov neeg hais lus, ua rau muaj kev poob ntawm kev ua tau zoo ntawm cov saib ze. Kev hloov pauv ntawm daim duab raj roj raj tsis tuaj yeem siv tau, yog li nws tau kwv yees tus nqi ntawm lub ntsuas tshiab (daim duab raj).

Muaj 2 txoj hauv kev los kho koj lub TV's magnetization: +
- thaum lub tshuab hluav taws xob tsis tshua pom tshwm hauv TV, kev tiv thaiv tau tawm tsam xws li qhov cuam tshuam uas cuam tshuam cov duab ntawm lub vijtsam (lub voj kev sib tsoo). Nws yog qhov txaus kom tua lub TV thiab tso nws nyob hauv kev tos (so) lub xeev rau ob peb mus rau ntau teev (nyob ntawm TV qauv).
- yog tias lub "demagnetization voj" ua tsis tiav, tom qab ntawd koj yuav tsum tau yuav, lossis qiv zoo dua, lub khaub thuas tshwj xeeb uas demagnetizes koj lub TV CRT. Thaum demagnetizing nrog cov khoom siv no, cov kab ke tseeb ntawm kev nqis tes yuav tsum tau ua raws, uas tau hais kom meej hauv cov lus qhia ua haujlwm. Lub hauv paus ntsiab lus ntawm CC qhov ua haujlwm tsis zoo tuaj yeem hais qhia rau koj los ntawm tus phooj ywg los ntawm koj, tej zaum, yuav nqa lub cuab yeej no.
