Plazma lg 42pj550 USB áramlimit
Üdv Mesterek! Fenti készülékkel kapcsolatosan lenne kérdésem az USB mekkora árammal terhelhető? egy 2,5" winyó tartósan üzemelhet róla? Természetesen nem külső tápos. Előre is köszönöm!
LG CE-28H86ST Nincs készenléti.
Szevasztok! Nem világított a készenlétit jelző LED. Széthúztam a tévét, megáldottam. Mindig hasonlóan szoktam kezdeni, mielőtt elkezdeném a hiba keresését. Azaz a gyanúsítható pontokat végigforrasztottam a táprészben, a gyanúsítható elkókat (ESR) kicseréltem. Például a C808 100uF 35V. Erre eltűnt a hiba. Nem szeretném, ha visszaköszönne. IC801 STRF6656 táp IC van benne. Ebben a tévében nincs T803 készenléti trafó. Mindössze egy darab RL801 relé van benne a demagnetizáláshoz. Olyan rajzot találtam, hogy: MC007A_CE28H86T.pdf A vizsgált részek egyeznek, de ez a rajz is opcionális részleteket tartalmaz. Most jár a tévé, mit gondoltok, keresgéljek tovább, szokott ezekben elbújni egy hiba? Köszi!
LG 26le3308 doesn't power up
Hi everybody, my first post here.
I've found on this site many information and the service manual about the TV in subject, but I stumbled upon a strange issue.
I repaired the earphone socket (pic attached) that had been stripped away and now the TV doesn't power on, it only gives a short beep when you touch the power on button and nothing happens using the remote. I checked the usual things (audio paths, cracked solderings, damaged tracks, power supply, power rails), but I cannot found what's wrong.
Any idea/clue on what to (double) check this time?

Thanks in advance smiley
