LG LM556200 Power Board LED Blinks 4 times
 LG 55LM6200  Screen goes dark after a few minutes, suspect protection mode is engaged-- no sign of thermal issue. On power board there is a LED, blinks amber in 4 blink cycles. Measured voltages ok, both backlight strips appear to be good. I have the SM, there is no reference to this power board LED, beyond the fact that it is there. Does anyone know what the blink codes are for these LG power boards? Thanks!

Aki tud írjon merre keressem a bánatát,relé, ic-fesz stb..ja még annyi a tápelkók ellenőrizve. üdv a mestereknek! fragola.

LG32LC41 ZA LCD Tv nem indul (LP78A chassi)
Üdv. Mester urak! A tv nem indul, a táp az STV5V- ot kiadja. A LED nem világit. IC 500 tápfeszültségei megvannak.A quartzon nem tudok mérni rezgést. Azt szeretném kérdezni, hogy indulásnál szkóppal kellene-e látni a resetelést? KA75270 reset ic van benne, mikor rákapcsolom a készülékre a feszültséget akkor az ic kimenetén megjelenik a feszültség, de nem látom, hogy kis időre testelné a reset bemenetet.
