Sunt si cu 07 ,04,01in coada.Am avut eu una cu 06 de la un display busit,dar am vandut-o.Parca e cu memorie inclusa in VCT.Afara n-are decat un 24c32.

 

Asa e, are spi-ul inclus in VCT, am rescris vre-o doua bucati cu postalul(nu aveam atunci RT-ul)

Am facut factory reset si la fel face.

Circuitul incercuit este hc4066ag Quad Analog Switch/ Multiplexer/Demultiplexer

Acum 14 ore, Costica Tv a spus:

Daca asta e singurul defect, nu prea as crede sa fie din soft(VCT)....c-urile de aluminiu prezinta un grad mare de uzura...un test rapid cu feonul(incalzite bine), apoi rescris eepromul....cred ca merge si gol.

Am incalzit cu feonul si la fel face.
