Sziasztok.Samsung CW29A114N/chasics:ks7a/ ,az a probléma bekapcsoláskor 3-4-et villan az elején a led és a villogás ütemébem kattog benne a relé.Utánna működik szépen,de ha ki akarom kapcsolni akkor relé egyfolytábam kattog és villog a led.Gácsi.
Jó estét mindenkinek!
A hiba vízszintes csík volt. Az IC301 LA7845 ki volt durranva,a D402 táp dióda zárlatos volt, az R424 tápellenállás szakadt volt, a fólia amelyik a D402 felé ment felégett,a D203 zéner zárlatos volt
Ezeket kicseréltem,és még kicseréltem a táp kondenzátorokat mind:C302, C307, C402, C404.
Megjött a kép, viszont az IC nagyon melegszik.Pár perc után süti a kezem a hűtőborda.
Ez normális ennél a tipusnál, vagy van valami módja a melegedés mérséklésének?
Köszi előre a segítséget.

Szevasztok!
A fent említett szerkezetből az ügyfél elmondása szerint néha sípoló hang tör fel.
Valszeg valamellik tekerenc sípol.
Nem kívánom, hogy a monstrumot idecipeljék.
Azt tervezem, hogy az alaplapot náluk kiépíteném, elhoznám és a gyanusított tekerencet fixálnám...
Mellikre jellemző, hogy csipog?
Poz. szám?
Mivel lehet tartósan elcsendesíteni?
Megtisztelő válaszaitokat előre is köszönöm.
