Tub defect sau puternic magnetizat ?

Recommended Posts

Va salut ! Am un televizor Sony KV-21T3K care deformeaza puternic culorile in colturile de jos , am incercat de mai multe ori sa il demagnetizez cu bobina special facuta , i-am verificat sistemul propriu de demagnetizare , i-am scos difuzoarele afara , deflexia nu fusese miscata de pe pozitia ei originala , am incercat sa o reasez , am si rotit-o cu 180 de grade insa petele raman in acelasi loc.Tind sa cred ca este masca deformata cu toate ca nu se observa lovituri in carcasa insa vreau sa va cer o parere inainte de a aruca tubul .Imaginea arata asa :multumesc !

Cu alt tub va merge 100% bine indiferent ca la asta este masca de vina sau magnetizarea..Eu as scoate din cupla bobina tvului si as incerca asa demagnetizarea apoi rotirea bobinei de deflexie cu tvul pornit sa vad cum se misca petele.

Am incercat si ce ati spus dvs, am pus si alta deflexie , petele raman in acelasi loc , este masca deformata :sparge: Multumesc pentru sfaturi !
