Yo5odl Posted May 9, 2022 Share Posted May 9, 2022 (edited) Buna ziua! Acest tv este echipat cu placa de baza 17MB110 sursa 17IPS12 display VES490UNDL-2D-N11 porneste , apare logo apoi in 10 secunde intra in stby. daca pornesc cu telecomanda iarasi se repeta. am verificat sursa si convertoarele DC-DC toate tensiunile sunt ok. am incercat sal resuscitez cu stick dar nu vrea sa porneasca update. ma poate ajuta cineva cu fisiere bin pt U81 MX25L1606E si eventual pt U80 MT29F4G08ABAEA ?

sesebe Posted May 9, 2022 Share Posted May 9, 2022 Sursele le-ai verificat cu osciloscopul? Verificarea doar cu multimetrul este useless in cazuri de astea si nu elimina o posibila defectiune la surse. Quote Link to comment Share on other sites More sharing options...

Yo5odl Posted May 10, 2022 Author Share Posted May 10, 2022 cu acest dump Digihome palpaie ledul rosu de 5 ori si se opreste, am pus stick-ul, se vede ca face upgrade, palpaie rapid vreo 3 minute dar tot aceasi rezultat ca se opreste dupa pornire Quote Link to comment Share on other sites More sharing options...
yokoono Posted May 10, 2022 Share Posted May 10, 2022 (edited) Sper ca ai rescris memoria cu programatorul si nu cu stickul. Daca ai rescris-o si nu se vede nici o modificare treaba este mai complicata. Edited May 10, 2022 by yokoono Quote Link to comment Share on other sites More sharing options...
Yo5odl Posted May 10, 2022 Author Share Posted May 10, 2022 memoria am scris cu programatorul , tot se opreste. apoi am facut upgrade cu stick , dupa ce termina procedura tot se opreste. pe urma am demontat U80 MT29F4G08ABAEA si da eroare la citire. acest nand sigur e defect urmeaza sa-l inlocuiesc.

Yo5odl Posted May 12, 2022 Author Share Posted May 12, 2022 (edited) Am incercat cu mai multe dump-uri de la rusi dar nu da semn de viata doar palpaie , numai cu dump-ul original porneste-se opreste care doar cu erori am reusit sa-l citesc Edited May 12, 2022 by Yo5odl Quote Link to comment Share on other sites More sharing options...
