Laptopul Acer 8930 nu are imagine

Buna ziua,

 

Am un laptop Acer 8930 ce nu are imagine, el porneste, se aprind ledurile de power, HDD, miniconsola, insa nu am imagine.

 

Are cineva sa mi dea o schema opentru a analiza problema mai in de amanunt, nu am gasit decat service manual, dar nu am nici o schema.

 

Ma intreb daca sa zicem placa video dedicata ar fi arsa, defecta, mie laptop-ul ar trebui sa mi mearga si fara aceasta placa??? si sa mi ceara placa video dedicata in cazul in care rulez jocuri, etc. Sau cele 2 placi nu pot lucra decat una cu cealalta?.

 

Tensiunile de 3.3V si 5V sunt prezente pe placa , nu mi dau seama ce ar trebui sa mai verific, sa localizez defectul.

 

Va multumesc!
