Sziasztok! A fent nevezett tv-hez kérek javítási tanácsokat. A hiba jelenség: ki veri a biztit, és a táp meghajtó tranyó (ON 4827, cserélve BUT 12-re) azonnal elszáll. A tranyót kiforrasztva, bekapcs. után a primer fesz. rendben (285V), és a készenléti táp is elindul. Köv. lépés: új BUT 12 be, bizti helyére 60W-os izzó. Az izzó közel telj. fénnyel világít,(a tv-re így csak kb. 60V eik) de a táp el kezd működni (természetesen a szekunder kőrben a névleges feszültségek töredékei, kb 40% mérhetők) Egyszerű eszközökkel mérve egyéb zárlatos, vagy szakadt alkatrészt -idáig- nem találtam, ja és a BUT 12 kollektor "hidegítő" 1,5nF cseréltem, de hiba továbbra is fenn áll. Előre is köszi.
Unreliable start. Mostly Led flashes red once every 4 secs suggesting Power Unit or LCD Panel. No Start
Sometimes normal start
Thanks for any help.
