sziasztok érdekelne egy benq t905
lcd monitor táp rajza olyan problémám van vele hogy a fénycsövek vezérlése nem müködik 2sc 5707-es fet-ekekkel van
Sziasztok!
Keresek a címbéli monitorhoz flash tartalmat (mentést).
RTD 2122L (vagy RTD2120L) procit cserélni kellett, de program nélkül nem működik sajnos.
Köszönettel előre is.
Üdv: Sándor
Sziasztok !
Benq Q7T4 LCD monitorhoz keresnék táp-inverter panelt.
Köszi: Pgimv
Sziasztok!
Hibajelenség: nincs kép.
12V és 5V táp rendben van (12V helyett 18-19V van), hibát az inverter környékén gyanítom.
Inverter rész 3A biztosítója kiolvadt, Q759 (2SC5707) kapcsoló tranzisztor zárlatos, panel két inverter trafó környékén meg van barnulva. Tranzisztort cseréltem. Ezután bekapcsolás után rövid időre halványan megjelenik a kép, majd eltűnik.
Kicseréltem a vezérlő IC-t is (TL1451AC), de nem változott semmi..
Rajzot a Tanyáról szedtem le, Q7T3 típusjelre keresve.
Hogyan tovább?
Gondolkozom a LED-esítésen is, ha a javítás nem jön össze, vagy túl sok energiát kell beleölni.
Üdv, lcsaszar
