Astazi am incercat sa readuc la viata un optibox. Simptomele era asemanatoare cu cele descrise de esteticu; comunica cu pc-ul prin dream-up, pot instala imagini, dar nu afiseaza nimic pe tv si ramane ledul verde aprins fara sa comunice cu telecomanda. Sursa a fost schimbata, telecomanda verificata....la fel si cablurile video.
Am incercat cu jtag. Acesta e logul:

Se pare ca e o problema pe partea de video. Daca as putea sa vad un log la bootare poate mi-as putea da seama unde e problema. O sa incerc cu hyperterminal cu ajutorul unui cablu serial. Poate reusesc ceva.
-
Pentru conectare la dream cu ajutorul hyperterminal e nevoie de cablu null modem.
Trebuie puse urmatoarele setari:
COM port 1 (sau 2)
- Bits per second = 115200
- Data bits = 8
- Parity = None
- Stop bits = 1
- Flow control = Xon / Xoff
La mine apare asa:

Ai verificat tnsiunile 5v. 3,3v. 1,8v. 2,5v?

Cele de pe placa de baza sunt OK.

Am rescris bootloaderul (OK), am reinstalat imagine (OK), dar totusi nu merge. Inclin sa cred ca e o problema la placa de retea.

Incearca sa masori alimentarile de AX dupa bobinute ,L1,L2, si schimba condensatori electrolitici C63,C17,C23,iar apoi scote ax si porneste aparatu sa vezi ce mai vorbeste cu tine
-
Inainte de a scrie bootloaderul verificati f bine tensiunile de pe sursele interne ,sant simtome de ,,Adios amigo daca o tensiune nu este in parametrii ,asa ca ,atentie mare.
---------- Post added at 14:57 ---------- Previous post was at 14:55 ----------
Ptr @radutiu ,AX-ul afecteaza numai daca este scurt pe el sau gaura ,posibil la descarcari atmosferice sa crape si flash-ul
-
Flashul il vede daca nu-l vedea nu apuca sa-l identifice si sa-l scrie
-
Nu am schema ca sa vad ce anume se verific. Pana una alta am luat unul nou si am verificat in consola ce scrie la bootare. Problema la cel vechi e placa de retea. Priviti logul la un optibox bun:
