DVD player defect,posibil dump alterat

Recommended Posts

Sanatate permanenta! Placa de baza sa-i zicem(are 8X8 cm.)--AL1389L.Alimentarea +5/+12V corecta.Nu aprinde afisajul nu face comenzi.DVD player-ul e inclus intr-o "boxa" portabila  PORT 8 DVD USB Radio.Am scos partea de afisare si comenzi si am probat-o intr-un DVD player BUNTZ--cupla identica nr.de pini,semnale si e OK.Pe un site strain se recomanda rescrierea memoriei flash EN25F80.Are cineva dintre domniile voastre un dump pt. asa ceva ori vreun sfat?Poza e de pe net dar e identica cu cea reala.Multam! PS- am citit memoria,daca e nevoie postez dump-ul.

Pt. d-l Bughiu: nu se incalzesc,sunt buni,scosi de pe placa si masurati. In ce priveste sfatul d-lui Spitfire doar metoda 2 as putea-o incerca.Multam amandurora pt. ajutor !

Pe astea le stiam iar bin-ul extras e cel din #12.Am scris dump-ul de la tine si nu misca nimic.Stii cumva daca fara memorie mai afiseaza ceva al tau? Multam!
