No display on LCD but external monitor works fine

Thanks for your quick reply! I have already stripped down my MacBook before so replacing the cable is easy, as for the capacitor will re-soldering the joints work?

How would the cable lose a pin? And would the socket on the board have the missing pin inside it?

I will try your solution and post the results. Thanks again

I really think you need to focus on the connector first.

The cap likely will need replacing if you try to re-solder it as the contact surfaces have degraded to the point any soldering will likely fail to adhere to the part.

Forcing the cable into the connector at an angle, it's just very delicate! Use a magnifier to see if you can spy the remains in side the connector. Its possible the pins inside are also damaged by the loose piece.

So I ordered a new screen cable and fitted it, still no picture :(

just a quick question, is the screen working but the backlight is off/broken? using the external display make sure you have mirroring on so the same image will be on both displays. then take a light and shine it onto your macs screen... if the screen is not working at all then it will stay black, if its just a backlight issue, you should be able to make out portions of the screen image depending on the angle you get your light at...

just trying to help you get a more precise symptom list for the gurus on here

@xshawk - Luke stated it was:

"I connected it through HDMI to an external screen and it shows up fine, everything else with the laptop works fine too."
