A nevezett beteg azt produkálja, hogy bekapcsoláskor bevillan az LG logó félig, a másik fele a logónak teljesen csíkos. Vibrál, majd 3 másodperc után eltűnik, és fekete lesz a kép. A háttérvilágítás megy, de nincs kép. Mi lehet a gond?
Köszönettel:

| Sziasztok. Keresek e fenti LG oledhez mainboardot. EBU63585001 |
Sziasztok !
Javításra került hozzám a fenti LCD tv táp(LGLP2637HEP ) hibával a szokásosnak mondható 6V-os problémával.
Q209 smd FET mellet 2db dióda szokott lenn D251 és D252.
De ebben csak D251 van beforrasztva ,D252 helye viszont gyárinak tünik,mintha soha nem lett volna itt alkatrész.
D251 anódja a testre katódja Q209 (IRF7807Z) G-re megy. D252 anódja Q209 S-re, katódja Q209 G-re menne,ha benne lenne.
Mi a tapasztalatotok ,ilyen változat is lehet ?
Üdv.
Van egy ilyen TV-m és két hete már így sípol, mostanra már elviselhetetlen lett, inkább be sem kapcsolom.
Anyámék/idősebbek nem hallják, de minket fiatalabbakat nagyon zavar.
Belülről teljesen kitakarítottam, de semmi változás.
Szerintetek mi baja lehet, javítható?
Kezdő vagyok még TV javításban.
Előre is köszönöm!
