Hi Folks,
I have a Dell inspiron mini 1012 laptop but there is no back light, although i can see the user interface fainthly in the background. The back light comes ON instantly when switch ON and goes OFF (so-called 2s to black). The laptop works well with an external display.
I've opened it and tested the LED back light to be OK (by testing all the LEDs and all lighted-up). The logic board fuses all tested OK and I've measured the voltages as well as the one directly at the back light connector and it reads ~15V and stable but the backlight doesn't still turn on. However, if i touch the metal casing of the back light, i can see all the LED lighting dimly. What could be the issue and what / where more can i do / check?
Let me know which read need emphasis, so that i can take a better photo of it. My phone camera can't take a better photo of the entire board -- my apologies.
Thanks
