JVC LT-32E33W firmware hiba
Sziasztok.
A címben szereplő TV-n megjelenik a logó, majd tovább semmi. Ezután gombokra sem hallgat. Firmware hibára gyanakszom, valaki tudna segíteni vele? 

Minden jót,
János
JVC LT-40VF52M, 17MB211S, standby LED flashes, it doesn't turn on
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:
