crt tv WESTWOOD mod. HA5-21US-A sasiu K-2129TOP-D A/0

Recommended Posts

As dori schema acestui tv echipat cu     
   multifunctional  TDA11156PS/N3/3
                memorie  24C08
                sursa  FSCQ0765RT opto EL817 , 6diode in secundar, TL431~componentele din sursa au prefixul 5**(D,R sauC)
               cadre TDA8172
              sunet  TDA7266
          trafo linii BSC25-N0608
       comutator AV  CD4052
       tuner  DWE-8053-V (LONGSIGN)
Schema prezenta pe forum cu acest sasiu nu corespunde, precum si multe altele gasite.Problema este de sursa, IC schimbat, diode, condensatori,opto, TL431, verificat eventuale probleme in secundar , tot nu porneste sursa.A pornit dupa schimbarea FSCQ0765 si a mers cam 30 de secunde, cam atat.Tv-ul a mai fost la cineva, ma gandesc a nu fi schimbat ceva aiurea (s-a mai intamplat).Multumesc anticipat!

Ca si aplicatie pt. CQ0765 seamana oarecum, desi sunt diferente destul de mari, cred ca printre multele scheme care le-am gasit ,ar fi si aceasta..., dar stiti cum e : "ce nu a reusit sa faca D-zeu in 6 zile..., restul s-a fabricat in China..."

Multumesc mult d-l Palcu!..., mai "cercetam"...
