Salut !

Am la reparat Acest Lcd cu mainboard TP.SIS231.PT85 cu panel LC320TU3A , caruia i-am skimbat softul prin metoda stick , si

am intampinat si eu aceeasi problema ca in topicurile precedente , si anume butoane inversate la comenzi si nu mai recunoaste telecomanda.

In fine dupa toate astea am decis sa ii scriu memoria flash cu un dump (in prealabil am salvat dumpul de pe memorie- nu cel original) si apoi surpriza : nu mai pornea deloc si nici sa ii mai bag firmware cu stickul nu mai mergea statea doar in stand-by. Pana la urma am reusit sa il fac sa porneasca cu dump si soft dar nu mai porneste bara de leduri (meniul se vede cu o lanterna pe panel , ia comenzi de la butoane) tensiunea pe bara fiind de 39Vcc fata de vreo 70. Am schimbat si OB3350CP controlerul ledurilor dar la fel.

Rugamintea mea ar fi o schema al acestui sasiu si o parere despre ce fenomen se intampla .


Pentru eventualitatea ca cineva mai are nevoie de dumpuri ale acestui sasiu atasez Linkuri cu dump si Firmware
