Sziasztok!
ACER AL1912 monitorba keresek MRT M8064I típusú IC-t.
A hibajelenség a következő. Elindul a monitor ACER logo megjelenik, szépen elhalványul, aztán háttérvilágítás megy, fekete kép, LED zöld, de gombok nem mennek. Ki sem lehet kapcsolni. EEprom-ot cseréltem, de nincsen változás. Szerintem ez a halott, mert a gombokat is ez az IC kezeli.
Ha valaki találkozott ilyen hibával és nem az IC volt, az kérem ossza meg velem a tapasztalatait.
Akinek van ilyen IC-je, az legyen szíves segítsen meg vele.
Köszönöm!
Üdv.
Jó napot
Kérdezném Acer1711 típusú monitor elindul-e számítógép nélkül.No signal stb.felirattal?
Köszönöm
Van egy Acer AL1715 típusú monitorom, ami induláskor 3-4 másodpercig rendesen mutatja a képet, majd nem látszik semmi. Elemlámpával bevilágítva látszik halványan a megjelenített kép. Innen gondlom, hogy a háttérvilágítással lesz probléma.
Valamint halk ciripelő hang is hallható, mikor a monitor nem ad képet.
Nem igazán tudom, hogyan tudom kideríteni a hiba pontos okát, ezért gondoltam, hogy itt kérek segítséget.
A segítségeteket előre is nagyon köszönöm!
Hi,
I'm sorry for writing in English, but I don't understand any single word in Hungarian and I couldn't find an English subforum there.
I have changed the LVDS controller and now it's working perfectly, but I need help with the backlight. The CCFL lamps in the screen are OK. I connected the screen to another inverter (from BenQ T705, made on TL1451 which also has "protect" function) and the backlight worked perfectly. Again, I connected other screen to the malfunctioning ILPI-075 inverter and the screen also goes blank.
I changed all THT electrolytic capacitors on the board, but not much has changed. Before, the backlight was turning off almost immediately, now it glows for 1-2 seconds and then turns off.
The HV side of inverter transformers is about 470 ohm, they look OK.
I measured random capacitor in the +16V line, which is supplying the high voltage inverters.
We can see how the voltage went down while the backlight was powered on.
Also, the ON/OFF signal on ICL837's pin 8 is always present after powering up the power supply, even after the backlight turns off.
I don't have any idea what to check now..
