Verificare traf linii tv

Recommended Posts

Salutare prieteni, vin la dvs cu rugamintea de a ma ajuta cu o idee simpla dar eficienta de verificare a trafului de linii din tv, nu dispun de aparatura pentru verificare acestor transformatoare de linii. Multumesc

Sanatate permanenta ! O sa-ti dau o metoda (nu e "profi" si nici 100% concludenta) pe care am folosit-o zilele trecute : o sursa recuperata dintr-un TV>pe bara B+ se leaga un bec>pornesti sursa=becul se aprinde>legi doua fire pe pinii B+ si colector ai trafo. linii>un fir il legi la masa sursei iar celalalt in anodul redresoarei din care se face B+ la sursa.Traf. OK=becul ramane aprins , defect se stinge becul.Am probat traf.uri sigur defecte si sigur bune (chiar unul nou).Recomandata de @Mac01.

Simplu de tot:

-jos BU de pe placa,apoi facut strap CE,

-intrerupt pinul B+ al trafo. de sasiu,si legat in anodul diodei de B+,adica la trafo. chopper,

-urmarit daca apar tensiuni"recuperate",daca trafo se incinge,etc.
