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 tv sasszija: 17MB62-2.5
Lehet ezt a sasszit factory resetelni?
Köszönöm!
Sziasztok!
Jó kis occo tuskós tv. Még a JVC is elhatárolódik tőle. Tápok jók a main-on (T.MT5310.91A 12016)is. A szokásos firmware hibára gondolok amit bele is írnék az MX25L6506E flash-be.Viszont nincs mit bele írjak. Valakinél van-e működő ilyen tv amiből ki lehetne menteni a firmware-t? Előre is köszi.
Sziasztok.
Bajban vagyok. Adott egy JVC 11AK19Y-os tv amiben szerintem beteg a PTC. Az igazság hogy már nagyon régen cseréltem, akkor mindig jó lett, most beraktam egy másikat egy Philips tv-ből és rögtön kilőtte a biztit. Ami benne volt az egy MZ73B 14ohmM (ez van ráírva), és amit találtam a HQ-nál az pedig ez: http://www.hqelektronik.hu/info/hu/ptc30rm270v.html és nem stimm valami szerintem. 30/380ohm a HQ-s az enyém pedig 14ohm-os, pedig a betűjelzés ugyanaz. Valaki világosítson fel hogy jó-e, mert ami kilőtte a biztit az 35/165ohm-os volt.
Köszi előre is.
Üdv
Ide írom mert ugyan az a TV és elakadtam. Ez egy JVC és nem indul el. A tápban cseréltem az MC ic-t, a fet-et, a puffer elkót, az optocsatolót és semmi. A készenléti piros led 3-4 másodperc múlva kigyullad és ennyi. A szekunder oldalon nincs meg a 150V és a többi is hiányos. Segítsetek légyszi hova nyúljak mert most még gondolkozni se tudok, van egy kis egyéb baj. Viszont meg kellene csinálnom mert az enyém és lemaradok a jóról. :)
Köszi előre is!
