Sziasztok! Fenti készülékben 6871qyh045c Y main van. Csereszabatos vele 6871qyh036d y main? Véleményeket előre köszönöm István
"FONTOS! Olyan fórum téma nevet válassz, ami beszédes, minél pontosabban illeszkedik arra, amivel kapcsolatban írsz. Egy lehetséges jó elnevezés
pl: ORION LCD PT26S chassis 17MB12-2, a tápja nem indul
Az nem elég, hogy pl: "LG LCD-TV" vagy "HP laptop" és hasonlóak. Illetve érdektelen, nem releváns információt se tartalmazzon a cím!
A helytelenül elnevezett topik felfüggesztésre, majd 48 óra után törlésre kerül! Felfüggesztett állapotban nem tudnak mások addig hozzászólni, amíg ki nem javítod a címet.
A hibás cím utólagos javítása (48 órán belül) a "Szerkesztés" fülre kattintva végezhető el."
hi.
a fenti tv-nek elment a fénye..
hang van, rávilágítva -halványan- kép is látszik..
a táp panelja . BN 44-00468a
az inverter panelja: SST320-3UA01
kerestem a szokásos oldalakon, de ez a tipus nagyon fekete báránynak tűnik, mert semmi lényegeset nem találtam róla.
valakinek lenne esetleg rajza-tapasztalata-netán beszerzési forrása a panelokhoz vagy netán-netán bontott paneljai??
üdv: egon

This is a LCD TV brand EMERSON, model LC320EM3F and is completely death.
At first revision, we detected some bad components in the switching power source:
Switching MOSFET K10A50D, RESISTOR 0.19 Ohm, 2W, transistor switching controler 2SC5344, Zener Diode 1ZB36 (36V) and the 4A fuse.
I had the SM of LC320EM9 model, so, the values of the components are different.
I replace them all twice and they always broke again! FRUSTRATING!
Then I realyze that changin the values nearly to the LC320EM9 model, I would obtain better results (see FILE ATTACHED)
I replace the 0.19Ohm resistor by a 0.39Ohm, maximizing the pulse received for the control transistor, for that purpose, also changed the 2.4KOhm resistor for 5.6KOhm. The switching MOSFET used was IRF640 replacing K10A50D, and transistor 2SC5344 was replaced by 2N5551. Finally we add a Zener diode not included in original board (marked with blue circle) limiting the colector voltage and gate voltage to 26V.
For short, when we connect the power cord, every thing was fine, except than voltages at secondary of main transformer, was only 3.2V DC in all rectifiers.
Found a diode in short-circuit (circled in red), replaced it and BINGO!, the TV return to live again!!!!
I Hope it serves as a nice experience for the future.
