ionutz1985 Posted May 16, 2015 Share Posted May 16, 2015 salutare mesterilor. am o problema la backlightul la acest tv, se stinge la 2sec dupa care ramane imaginea si sonoru am verificat electrolitici pe parte de invertor dar nici o sansa. Link to comment
tehtronics Posted May 16, 2015 Share Posted May 16, 2015 Este cu FAN7311 ? Verifica +14,5V, lipituri trafo invert., conexiuni lampi ... Pune o rez. 560 ohmi intre pin1(FAN7311) si masa...asta doar de proba Link to comment
