adam, just to make sure I understand correctly. We are talking about a iPhone 3GS with a new LCD and a replaced 6R8 backlight coil. It still does not have a backlight? Is the phone being recognized by iTunes? can you see anything when you angle a light against the screen? Have you checked the contacts on the logic board to make sure they are not bend or broken?

adam, first off I recommend a different shop. The one you used should have known that the 3G and 3GS are not identical. Second I am not sure if he changed the backlight coil. See if you are going to get your money back :-) Anyhow, you do have a new LCD and digitizer. Check on the coil 6R8 repair and make sure that it was done right. If the LCD is good, the coil is good than the next issue will be the backlight IC. It is a BGA and needs to be reballed. Not necessarily a DIY'er task.
