Szevasztok!
Egyik saját, családi monitorunk, teljesen rapszodikusan kapcsolgatja le a CCFL-t,
nem az inverter tilt le.
Egyértelműen a prociból kijövő inverter on/off feszültség megszűnése okozza.
Átmelegítés, egyéb varázslás, nem járt eredménnyel. A main-board cseréje megoldaná e gondot.
Újat nem tudtam rendelni, de egy működőt szívesen vennék.
Mellékelem a képét.
üdv
Sziasztok!
Az említett monitorhoz keresnék scaler panelt/EAX52749301/, vagy a scaler IC-t/FE253MOH-LF/.
A problémája az, hogy szemeteli a képet.
Üdv:helpme
