Eroare 9 Sony KV21T1K

Recommended Posts

Sanatate permanenta ! Sasiu BE-4A , a avut STR- S5706 fript.Dupa inlocuire sursa e OK , tensiunile mici in regula.B+ e 144V (o fi bine...) la tub de 51cm. Eroare generala pe I*C , SDA sau SCL sunt tinute "jos" dpdv. logic-asa zice manualul.Nu sunt impulsuri de comanda pt. FL.Va rog un sfat , mersi ! LE-doar pt. fractiune de secunda apar impulsuri (cu BO decuplat de la B+) , mai caut.

strs5707  este  echivalentul  superior  ca  putere  al  lui  strs5706 ,  deci  problema  dvs  nu  este  cauzata  de  aceasta  inlocuire .  problema  reala  actuala  a  majoritatii  strs-urilor 5707  din  rsr  este  ca  sint  niste  rebuturi  de  2  bani  gauriti .  daca  sursa  este  echipata  cu  amplificator  de  eroare  de  genul  SE 1xy , schimbati-l  si  pe  el  ,  dar  si  optocuplorul . daca  nu  exista  SE1xy ,  atunci  incercati  direct  montarea  de  ups001 ,  pentru  ca  strs5707  de  buna  calitate ,  nou  si  la  bani  putini  este  f greu  de  gasit .
