Sziasztok.
A címbeli tévé inverter trafójának szekunder tekercsein az alábbi értékeket mérem ohmban:egyik tekercse 980 ohm a másik pedig 1030 ohm. Ekkora különbség (50 ohm) már trafóhibára utal? Amúgy mennyire szoktak megegyezni ohmikusan a szekunder tekercsek? A trafó száma: TMS93264CT
Egyébként a tévé háttér világítása nem műkszik, csak egy másodpercre felvillan majd elalszik tehát inverter hibás. Kérdésem még, hogy esetleg egy rossz csőtől megy tönkre a trafó vagy pedig simán a nagyfesz húz át benne?
Köszi!
Üdv Mesterek!
Ebbe a tescós csodába keresek flash tartalmat.
17MB82S a main, VES400UNES-05-B a kijelzője.
Köszönöm a segítséget...
Sziasztok!
Most kaptam :)
Megyek át mamámhoz a padlást rendezni, ma pont jó idő van hozzá, így csak később leszek gépnél.
Addig pár tapasztalatot osszatok meg velem légyszi, mikre figyeljek majd.
Bekapcs után a készenléti led zölden vibrál. Nem villog, tehát nem elalszik kigyullad és ezt ismétli, hanem csak vibrál.
Köszi!
Remélem nem trafós... Bár van egy komplett belem :)
Üdv:

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:
