Hi there! My Acer Aspire 7520G-302G16 does not

The video adapter is integrated into the motherboard. If it is the problem then the motherboard needs to be replaced.

If your notebook has an vga connector on it you can plug in an external monitor. If the external monitor works then your video adapter is good.

The next step, which is my guess, is that the notebook monitor or connection that is bad. The wires run through the hinges so they can get pinched or damaged.

Both of these possiblities will require expert-level skill to resolve. Taking apart a notebook can be very tricky. I recommend you go to Acer's website and locate a service center.

If you are feeling very brave you can Google for assembly instructions and go to eBay and find spare parts. Use a digital camera and take pictures as you take it apart so you will know how to put it back together.

If this helps please vote for my solution.
