probema monitor

Recommended Posts

salut. am un monitor dell E772p. problema este ca  imi apare pe ecran "main menu" din senin si se autoseteaza singur, dispate cateva secunde si apare din nou. Daca incerc sa-l setez eu nu raspunde la comenzi.  Am dat o scanare pt. virusi dar nu au fost gasite probleme. Nici dupa restartare nu s-a remediat ploblema. Am pus monitorul la o alta unitate si  se  intampla la fel.

Stie cineva care poate fi cauza problemei si daca se poate face ceva.

Multumesc.

In cazul problemei de mai sus, foarte probabil ca memoria EEPROM a MCU-ului, unde sunt stocate variabilele, sa fie compromisa.

Ati gasit cumva si un manual de service ? Va intreb lucrul asta deoarece eu nu am gasit nicaieri asa ceva.

 Am de mult timp acest monitor, nu am gasit un manual de service.Azi cand am deschis pc ul imi apare "control menu is locked" iar butoanele de setare nu mai raspund la comenzi, dupa un timp a inceput iar sa se autoseteze la fel ca si ieri. Credeti  ca problema este din unitatea centrala?(nu prea stiu ce inseamna memoria EEPROM a MCU-ului).

Multumesc oricum pt raspunsul anterior.

Incercati sa inlocuiti switch-urile. Acestea in timp oxideaza si dau comenzi aiurea in placa digitala.
