Hi , I need some help to fix this problem . I have inspiron N5110 and the problem is no display , however , when connect external display in DB-15 ,display is OK. I test LCD on another laptop , LCD is ok . where is the problem that causing no display ?? please , I need schematic sheet for N5110 thanks
Either it's the LCD video cable like urie said, or your GPU needs reballing. If a BGA (Ball Grid Array) processing device gets too hot, the solder cracks and the processing unit will have a bad connection.
Yep, I've replaced cables before, I agree. You could even try your cable in the other laptop to verify.
Since it works fine on external monitor then it can’t be the ram or the gpu, check the monitor switch that turns the display off when the top half is shut that could be stuck.
Actually, abbs is right, I kind of looked past that, try and external monitor to eliminate a faulty GPU. Thanks abbs +1
LED screens tend to go bad on 1 drop. cheap tho 65$ for "15.6 however i see he tested it on another and works. problem is between GPU and LCD cable port on mobo.. if u unplug it with battery conected ive heard it damages something(diode or gpu). TAKE BATT OUT before doing LCD cable change.
