Helló mindenki!

Javítom ezt a monitort, púpos volt 3 db 470uF 35V kondi, kicseréltem, de sajnos elötte már elküldte az APM4048DU4 dual mosfet-et az örök vadászmezőkre. Mivel ez egy TO252-4 -es tokozás, nem tudom mivel tudnám helyettesíteni.
Az AOD606 jó lenne, de az sem kapható.
Van ötletetek?

Gege

Sziasztok.
A bevezetőben szereplő monitorba keresek veszek csövet. Még nem szedtem szét a hosszát pontosan nem tudom, de kívülről mérve 420mm. Tuti az a hibás mert rövidebbel működik, még azt megnézem hogy egy vagy kettő kell. Csak egy buta kérdés, nagyon homály lenne a széle ha beledugnám a 350mm-est? Előre is köszönöm a segítséget akinek van. Üdv.J

Sziasztok,

idekerült egy ilyen monitor. Az a baj, hogy az OSD néha átvált valami ismeretlen( szerintem nem is létező) nyelvre, melynek következményeként úgy néz ki a képernyő mintha különféle nagyságú négyzetekkel lenne telepingálva. Szerintetek kínozzam üres eeprommal? Vagy nem is eepromhiba?
(Valami szoftverezésről olvastam az előzményekben).

KÖsz.

Üdv.

Tamás

A témában szereplő monitor egyáltalán nem ad életjelet magáról. Bizti jó benne, munkaellenállás jó, a fólia nincs elégve sehol, kondik nem púposak, diódák nem zárlatosak. Abszolút nem indul a táp, semmit sem csinál. Én a táp IC-re gyanakszom, de nem merem megrendelni, mert 4 ezer forint körül van és az egész monitor sem ér nagyon többet. Szerintetek?
