Acer V223HQ - ILPI-075 Rev.A power supply turns off
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..
ACER GD245HQ Monitor nem üzemszerűen működik. Megoldva!!!
Kedves kollégák!
Valószínűleg Flash vagy eprom hibás a kicsike. A kijelző teszt üzem módban van a végtelenségig(szinek váltogatása). Ehhez keresnék tartalmat.
Elvileg a szokásos orosz aranybánya oldalon van hozzá.

Sajnos én ide nem tudok bejelentkezni(teszt kitöltést nem tudom értelem szerűen lefordítani). Ha meg tenné valaki,hogy letölti.Nagy lenne az öröm!!!
üdv.
Acer S221HQL csak egy pillanatra van kép! Kész!
Sziasztok! A fent nevezett monitor nem ad képet, csak egy pillanatra. De ennek a háttér világítása már ledes, rajzot nem találtam hozzá. Valaki találkozott-e már ezzel a fajta monitorral, hogy merre kezdjem? A tápban nem találtam hibás elkot, de a min-bordon sem, tápok 5V, 3.3V, 19V . A kijelző háttér csatin milyen feszeknek kellene lenni?
Acer V193W
Sziasztok! A fent említett monitorral kapcsolatban szeretném a segítségeteket kérni. A készülékben nemrégiben cseréltem CCFL csöveket és mint mindig most is csak másodlagos monitorként volt tesztelve a művelet végén. Nem is volt vele semmi gond,de mint később kiderült nem működik 640x480-as felbontáson,vagyis a a gép indulásakor nem ad képet. Feléled ugyan készenlétből de a kijelzőn nem látni semmit,egészen addig míg az oprendszer elnem indul. Szerintetek mi lehet a gond,merre keressem a hibát? Előre is köszönöm. Üdv mindenkinek.
