la unele clone cablajul este facut aiurea ...nu e lipit bine se poate sa se fi desfacut ceva , undeva...candva ...cand l-ai transportat
si astfel nu functioneaza corect
nu sunt elecronist ..dar unul mai bun poate isi da seama unde e hiba...daca nu... atunci cred ca trebuie luat altul
Din fericire si-a revenit.
Am uitat sa precizez un lucru foarte important, aveam imagine gemini 460 maxvar cu timebomb pe el, cu toate ca avea mac original. Nu stiu ce sa zic, a mers asa mai bine de o luna, dar ar fi coincidenta prea mare sa se fi activat bomb-ul exact in ziua cand am plecat cu el de acasa..
In concluzie mare grija cu imaginile cu bomb in ele :) se gaseste 460 fara timebomb oricum... Ciudat e ca mergea totusi dreamup-ul... poate are cineva o explicatie pt asta.
Azi m-am apucat si mi-am facut un cablu JTAG si am reusit sa-i rescriu bootloaderul. A mers din prima, si a durat 5 minute. De asemeni a pornit ultima imagine incarcata cu dreamup. A fost prima mea experienta de genul asta si ma bucur ca am trecut si prin asta :) stiti cum se zice, nu esti sofer pana nu faci o pana de cauciuc...
Am folosit un programel de DOS care nu a mers sub Windows 7 64 bit, doar pe XP. ( [Only registered and activated users can see links. Click Here To Register...] )
Cam asa arata cablul:

Multumesc pentru sfaturi si numai bine!
Sanatate!
Frumoasa lucrare, nimic de zis.
Dar si mare noroc - din cate stiu sunt doua variante de soft, pentru cele doua variante constructive de tuner - Philips sau Alps. Daca jucarica functioneaza, inseamna ca ai gasit varianta de soft potrivita.
E adevarat ca cele mai raspandite sunt tunerele Alps si, probabil si softul adecvat este mai usor de gasit.
Bafta in continuare!
Programelul stie si de alps si de philips. Eu nu am specificat si baga varianta pentru alps default.
Cam asta a fost output-ul la mine. Imi place mesajul de la sfarsit :DQuote:

am cumparat un dm500s azi si am pus o imagine gemini 4.60 si totul a fost ok ,a mers pe net am pus cccam,lam deconectat de la net iar dupa 1 ora lam oprit din telecomanda si lam pornit din nou si am avut surpriza sa am un mesaj "warning" precum e clona si ..................... si nu mai pleaca nici macar ledul nu se mai aprinde pe el.ce e de facut?
sa il duc inapoi la magazin?
ajutor urgent
pe mess daca se poate sony2567
Of Of Of...de ce ai pus gemini......??????
Mergi inapoi cu el...daca se poate ...daca nu JTAG scrie pe el. Se poate face dar cere un minim de cunostinte.
Pana la urma se pare ca acest time bomb actioneaza cand opresti receptorul din butonul shut down de pe telecomanda.Deci nu are nici un timer ci e legat de o conditie exacta.:)
PS: Cine nu e sigur pe ce are si stie sa ii faca jtag poate incerca sa opreasca si sa porneasca receptorul din telecomanda,pana la urma oricum se va intampla si din greseala.Sper sa nu ne trezim cu o avalansa de receptoare moarte.
O alta problema la DM 500 S clona... merge totul ok dar nu prinde niciun canal. Am incercat reinstalari de imagine, si cu serial, la fel.
Am masurat pe intrarea de LNB, unde ar trebuie sa fie 18V si 14V in functie de polaritate si am cam 2,2-4V maxim.
Ce poate sa fie? Trebuie alt tunner?
Am rezolvat, era vorba de tranzistorul Q72 si siguranta resetabila (PPTC) F70.
Problema e dezbatuta pe topicul [Only registered and activated users can see links. Click Here To Register...]

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:

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.

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:
