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..

Sziasztok!
Hozzám került egy ilyen acer monitor, két napig megy szépen aztán egy napig csak duplaképet ad aztán megint jó, én még nem találkoztam ezzel a hibával.Javítható egyáltalán.
üdv
Van két ACER AL-1715 tipusú monitorunk mindkettő ugyanazzal a hibajelenséggel, nevezetesen: időnként elpirosodik a kép majd egy idő elteltével visszavált rendes képre és megy tovább mintha misem történt volna.És ez ismétlődik véletlenszerűen.
Amugy minden látszik rajta rendesen csak pirosas árnyalatot kap a kép.
Ha találkozott már valaki ezzel a hibával mondja már el nekem általában mi okozza ezt a hibát ,hogy kevesebb időt kelljen hibakeresgetni.(A SM-ja megtalálható feltöltve.)
köszi

Kedves kollégák! Ritkán foglalkozva TFT-vel kérem tanácsotokat! Az ACER AL1714 monitor normálisan indul (kifogástalan világosságú és szinű ACER felirat) de utána a számítógép képe "túlvezérelt" jellegűen világos, a fekete világosszürke. Ugyanakkor az OSD menüt kérve az kifogástalan világosságú és szinű az általa elfoglalt képtartományban.. Cseréltem a main-board panelt, a jelenség változatlan. E pontnál kérem tapasztaltabbak segítségét!
Köszönettel: mehringa
