Senzor IR PixelView DVD player

Recommended Posts

Am un DVD Player PixelView model DVD912A. L-am imprumutat cuiva si cand mi l-a adus am constatat ca nu ii merge telecomanda.Telecomanda in sine pare OK, am testat-o cu camera digitala si se observa activitate la LED-ul IR.Am masurat si pe senzorul IR al DVD-ului. Am 5v pe alimentare, iar pe iesire imi oscileaza intre 0.7V si 1.2V. Daca bombardez senzorul cu semnale IR de la telecomanda pot masura pe senzor o scadere de voltaj de aproximativ 0,1-0,2V (pe pinul de output).Eu suspectz a fi defect fie senzorul IR fie oscilatorul telecomenzii.Cum as putea testa senzorul IR al DVD-ului? Pe el nu scrie nimic si nu il pot identifica.Multumesc.

Am decuplat circuitul senzorului IR al DVD-ului si m-am cuplat cu un senzor Ir facut de mine pt winlirc. Acum am 3.6V pe pinul de output al IR. Telecomanda tot nu merge, absolut nici un buton. Pot masura cumva iesirea de pe pinul TSOP-ului?? Nu am osciloscop, am decat un DMM DT9208A.Ma gandesc sa schimb oscilatorul din telecomanda, un 455. Maine ma duc sa-l caut prin magazine, prin casa n-am decat un 485 dintr-o telecomanda mai veche.. :smt005
