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:

JVC LT-32VH42L led tv Nincs háttérvilágitas /MEGOLDVA/

Vestel belsősElőször azt hittem tápegység gond, de probáltam másikkal azzal is semmi.Arra jutottam, hogy bontom tovább, A világitást 2db JL.D320B1235 számú ledcsík adja, kérdésem az lenne, hogy nem tudnátok megmondani milyen smd ledek vannak rajta, milyet lehetne rárakni a hibás led helyére,?Vagy valami más megoldás, led szalagból valamit összehozni?Most tartok ott ,hogy pattintgatom le a fényszóró vackokat, úgy gondoltam azt majd pillanatragasztóval visszarakom.

JVC PD-42B50BU tv melegedés után becsíkozódik
Ez a plazma kb öt óra után a fényképen látható módon becsíkozódik. Kontaktra nem reagál. Valami ötletetek? További járatás után a vizszintes csíkok sűrübbek lesznek. Láthatóvá tettem a képet.
