ACER AL1718A monitorhoz Flash tartalmat keresek
Sziasztok! Keresek ACER AL1718A monitorhoz flash tartalmat. Sajnos ilyen mentésem nincs, az AL1716, AL1717 tartalmakkal el sem indul. Súlyos táphiba miatt az órajel, a képhelyzetek nem állíthatóak be illetve pld. a függ. képhelyzet 100% fixen, 2 cm eltolással. Egyéb flash tartalmakat bepróbálva ezen paraméterek beállnak, de ha pld nincs menü, akkor hiába, használhatatlanok. Saját bin állományt többször visszaírva látszólag jó az első újraindításig. Valakinek mentése esetleg? Üdv: Sándor

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..
