Sziasztok!
A fenti monitor normál módon, azaz a számítógéppel együtt rendesen indul, bármeddig hiba nélkül működik. Ha viszont kikapcsolom a monitort, vagy beállítom a gépen, hogy használat nélkül lekapcsolja, akkor utána már nem kapcsol vissza, csak villog a standby led. Ilyenkor, ha kihúzom-visszadugom a VGA csatlakozót (csak ilyen bemenete van), akkor viszont bekapcsol. Még annyi, hogy induláskor, mikor betölt az op. rendszer, egy időre megjelenik ez a felirat: D-SUB POWER SAVING MODE.
Van valakinek ötlete, mi okozhatja a hibát?

This elderly monster arrived with the error “ 4 blinks “ which the manual suggest is a power board fault There are TWO power boards and a standby power board inside.
On removing rear cover there were two swollen 220uf caps on the standby board, sadly replacing them the 4 blinks remained.
Swapping the two power boards over[ as they look identical , gives a “ 2 Blink “ error , the limited info in the manual suggesting that the fault is on the lower board [ main 2 ].
Both boards have a PFC voltage of around 380 volts at switch on before the relays click out, I have done cold checks on both boards and there are no obvious differences.
The manual has only a block diagram of the power supply so it’s difficult to be sure of values / voltages.
My question is has anybody seen or worked one of these or similar beasts
Many thanks Ken

Sziasztok, kis segítségre lenne szükségem, kaptam egy Samsung 19" LCD monitort, sajnos az invertere nem működik. (nincs fény). Sikerült letöltenem hozzá doksit, de sajnos az inverter fet tranzisztorai megégtek, és a típusuk a doksiban sem szerepel.
Egy hibrid nyák van a panelhez forrasztva, MJ17BS. Panelen jelölés IP601. Tudna nekem valaki segítséget nyújtani, vagy helyettesítő fet-et találni?
Monitor típus: Samsung 920N, Type No: GH19LS
Előre is köszi, Dricsk
Sziasztok!
VG2439m-LED - ViewSonic monitor bekapcsolás után megjelenik a ViewSonic logo, majd az aktuális képernyőkép, 5-10 sec után sötét a kép és éppen hogy felvillan 3-5 sec időközönként.
Szétszereltem, semmi elváltozás a paneleken, csatlakozók szét-összeszerelve, tápegység kondenzátorain semmi elváltozás. Bekapcsolás után a jelenség ugyanaz.
