LG OLED55C9PLA TV does not start :(
Hello guys,

I have a LG TV OLED55C9PLA which does not start at all. Unsure
The only sign that is alive is some vertical colored lines on the right side of the screen that are appeared at the beginning and that's it. After that black screen.

I have uploaded a short video (more than 3Mb) to understand better what I mean.

If you have any experience from such problem please help me to fix it.

Thanks in advance.

LG RE29FB51 RQ MC036A nem hangol
Sziasztok! A készülék val szin villámcsapott. Eredetileg nagyon nehezen kapcsolt be valamint raszter hibás volt a kép. Képtartalom nem volt csak zaj vagy kékképernyő, onscreen rendben. Hangolási menübe nem lehetett belépni. Írtam bele egy eepromot ami hatására már rögtön indul, képgeometriát be lehet állítani és a hangolási menü is aktív. Viszont állomást nem talál, 5v-33v megvan. AV-ről sincs kép.Tehát csak kékképernyő és on screen van. Ami gyanus hogy az scl vonalon jóval kisebb a jelalak mint az sda-n. Tunert tettem bele változás nincs. A digiboxról lekötöttem már az alaplap scl vonalát, igy sem jó (szerintem) a jelalak. Szóval ha van valakinek működő digiboxa vevő lennék rá. A száma 6870VS1510B(2) MC036A
