-@alexreid a reflow probably will not work since you have images just not a backlight. I'd start by checking things like C1100 to see if you have 3.3V going to your backlight enable circuitry etc. (also possibly a backlight fuse) to see what the power situation is on that one. Post some good images of your board with your question so we can see what you see. Use this guide [guide|21499|commentid=417084] for that. We might identify the components in question. Check things like step 12 of this teardown [guide|6525] it shows your LED driver (HV9982) in the fuchsia square.
