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 a fenti Lcd tv-nek a bal szélén függőleges csikok láthatók.Tud valaki segiteni.Kép mellékelve
Sziasztok!
Ennek a tvének a tápjával szívok most, megszaladt a tápja. Eddig cserélnem kellett a 145V diódáját (HER308) a táp icét (NCP1207) fetet (2sk3562) két diódát a primer hűtőbordánál (BA159 ) még a biztonság kedvéért az optot (tlv817) és a TL431-et. Az ellenállásokat kiforrasztva átmértem a primer oldalon, de nincsenek megszakadva, a szekunder oldalon a TL ic körül is átmértem az ellenállásokat itt is jók. Bekapcsolva lüktetve csiripel, a 145v helyett 30V van a többi tápfesz sincs meg, a sor le van kötve, a hangvégfok is. Mit nem veszek észre, valamelyik tranzisztor a LM317-esek környékén?
Sziasztok !
Fenti TV-n csak készenlét van !
alaplap : T.MT5310.S97A
flash IC : 25Q64
Ha a tanyán is megtalálható 29" TV-hez való flash dump-ot beleírom, akkor elindul a TV , de nincs kép csak a háttérvilágítás jön meg...
Az interneten csak rossz dump van fenn...
Előre is köszönöm : LCDdoki
