Citire 24C64

Recommended Posts

Am un 24C64 de la un TV care aparea numai dungi si vreau sa-l rescriu dar nu pot sal citesc deloc.

Din pacate nu am facut in totalitate schema. Am folosit un 7805 sa alimentez 24C64 si nam mai pus o dioda zener ca nu e necesar pt cip.

Problema este ca imi zice device not responding cand il citesc, dar daca pun un 24C04 mi-l citeste bine.

Nu am pus nici diodele 1n4148 ca folosesc alta sursa de alimentare.

Nici nu stiu cum fac sa-l citeasca.

Poate e defect fizic EEPROM-ul.

Am incercat 2 de pe diferite tv-uri de acelasi model.Unu era cu dungi si altu era programare defecta. imi aparea 16:9 pe ecran si cand dadeam de butoane imi zicea parca in poloneza sau germana, for optimal perform...nu mai stiu exact dar nici nu puteam sa-l opresc din buton.Oare sa cumpar 24C64 noi?
