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:

hello
i need the software in the memory IC /eeprom of a jvc LT-42A85BU LCD TV. anyone can help please?
maybe someone has this board and want to make a copy? the software is damaged in my tv, it's useless now :(
Sziasztok!
Nevezett készülék villámlást követően nem adott életjelet. Tápegységének készenléti áramköre hibás volt. Ezt javítva már van készenlét, sőt (látszólag) be is lehet kapcsolni. Mérve hamar kiderül, nem indul az üzemi táp. Ennek meghajtója vélhetően rossz, hiszen mérések azt mutatják. Na itt jön a bökkenő, mert semmit nem találok róla... 1D11101.
Esetleg valakinek ötlete???
Köszönettel: Kiss Z.

Sziasztok!
TDA8358J, L402, C499,C408,... CSERE, és a hiba továbbra is fennál. Rossz lenne a TDA9365 20-as lába? Na fárasztjuk még egy kicsit. Az építő szándékú hozzászólásokat szívesen venném! :)
