Üdv. Mindenkinek!
Fent nevezett TV pár perc után (lefagy)el megy a kép,(háttérfény marad)újabb pár perc után a hang is megszünik.
A Videó és a fő procit(hőprofilosan)átmelegítettem, a fő és a mainboard tápjai rendben megvannak.
Emiatt keresnék hozzá eeprom iletve flash tartalmat.
üdv.
Sziasztok! Fenti plazma YSUS (EBR61018101) zárlatos Q16(IRGP4086 SUS DN) és Q11˙(30J124 SUS UP) valamint szakadt R503 és megnyúlt R729-el(mindkettő 2r2 ohm) érkezett. Cserélve kijelzőn 10mp-re fény megjelent - igaz nem homogén intenzitással, de teljes terjedelemben- majd újra elszállt mindkét igbt. Kijelzőn kívül okozhatja más is? Köszönöm a hozzászólást István
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!
