Acer Aspire 4710Z - Screen Display is not working. Pls suggests. However laptop is working with external monitor. would appreciate for early reply.
if u checked the bios settings and windows (operating system settings) and it appears to be ok, than it must be the hardware.
ccfl bulb, inverter, tape. try also to darken it to the minimum and change the display device back and forward again (keys fn+f6 or sth close)
