Tuner tv X3M tv AB300

Recommended Posts

Am tunerul din titlu , in care a curs ceva solutie (nu stiu ce ), Circuitul integrat,



Il suspectez de defect . Iam gasit soclul si contactele oxidate rau , cu ceva verde  , ca oxidul de crom . Ma gandesc ca sar putea sa fi alterat memoria .

Nu gasesc un datasheet ptr el .

Daca a avut careva de aface cu acest ci , as dori sa stiu daca este memorie programata . Si daca se poate programa , si daca cineva se baga sa-l reprogrameze . Sau poate nu este asa .

Ca forma arata asa . Are 11pini pe fiecare latura




Multumesc .
