Sziasztok,
megakadtam egy ilyen monitorral. Kb. 1 éve javítottam, akkor át lett kondizva (beleértve a primer puffert is) és működött is.
Most konnektorba dugva egy pillanatra narancssárgán felvillan a LED, azon kívül semmi. Háttérvilágítás sem indul egy pillanatra sem. 12V és 5V megvannak, 3, 3V is jónak tűnik de életjel nem látszik a LED egyszer felvillanásán kívül.
Mi lehet? Eddig táp-inverterjavításra mind elindult...
Köszi.
Hali!
Van nálam egy ilyen moncsi, tud valaki hozzá gépkönyvet?
Az a hibája hogy gondol egyet kikapcsol aztán be és így tovább, ezt hidegen melegen is megcsinálja...
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!

The backlight in my old Acer monitor is only half-lit and there comes a 50 Hz buzzing sound from the inverter transformers.
The LCD image itself is fine.
What could it be, the CCFLs, the inverter or the power supply, does anyone know? Are the CCFLs OK?
