Kedves elektro tanyázók az adott hangpanel beépítve van a monitorban , az alapvető nagy kérdés az lenne milyen háromlábú állat lenne a panelt meghajtó kapcsoló üzemú táp IC Mivel szublimálódot a fenn nevezett háromlábú állat tokozásának írott fele ezért nem tudom a típusszámát , ha valaki javított ilyet és emlékszik a táp iC típusára megköszönném a megosztását a tudásának. Üdv: teodor.

Sziasztok! Szükségem lenne ACER AL1916Csd tipusú monitor main board-ra. Tipus:715G1558-1-AC. A panel U401 és U702 ick között kb 5x5mm-es területen átégett. Köszönöm előre is István

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..
