Sziasztok.
A fenti tv-vel közdöttem.
Minden rendben van vele elvileg ha a menü gombot megnyomom a távon rendesen bejön a menü.
Ha itt lépni akarok bármerre kilép a menüből vissza a tv-hez.
Így nem tudok gyári beállítást se csinálni meg igazából semmit.
Epromra gyanakodtam, kivettem tettem bele üreset, így el se indult.
Tartalmat nem találok hozzá.
Szervíz manuál szerint FT3 sasszi.
Esetleg volt már ilyen hiba valakinél?
Merre tovább?
Köszönöm előre is.
I copied the spi flash and nand from a working board of the same model, but it still won't turn on and the standby LED flashes 13 times. Before reprogramming, the LED also flashed and the TV wouldn't turn on. It also wasn't possible to upload software via USB. I read this via UART:

Sziasztok!
Ezt a készüléket Angliából hozták be, de se BG, se DK hangnormán nincsen hangja csak sistereg. Próbáltam volna bejutni a szervízmenübe de nem sikerült 4725 kodokkal, vagy nem is itt lesz a gond? Segítségeteket előre is köszi.
Sziasztok.
A tárgybéli készülékkel küzdök.
Hang van,osd van kép nincs.Feltekert G2 vel szürkés visszafutásos jelenség van.
Tápfeszek rendben.Forrasztások rendben.
A VDP 3134 Y okozhatja a hibát?
Nagyon nem méjedtem bele egyenlőre.Találkozott már valaki ezzel a hibával?Segítségeteket köszönöm.
Béla
