acer aspire 5532, working fine, replaced lcd ribbon with one for web cam, now dark screen, can barely make out the images. Hooked to an external monitor and displayed fine. Installed the driver for the web cam and alls well on external monitor. How do I correct the dark screen issue. I dont want to use a external monitor and I dont think its the screen. I removed it and hooked to a dell inspiron and the screen lite up as it should. Have replaced the inverters twice so I know thats not the issue.
