I agree with some of the posts here, but I understand the OP's hesitation. Until you have done it, it is a bit daunting. Removing the pickguard is not hard, but if you've never done it, it can be "tricky". Sure, it's only 8 screws, but you need to pay close attention to how tight they are / were when you remove them, and not over tighten or under tighten the screws when putting them back. That is a "feel" issue; if you've not developed that "feel" with hand tools and wood, then it's easy to under tighten and have them fall out, torque down the screws and warp the pick guard, or worse yet strip the screw holes. However, a bit of care and a few techniques can prevent that. I would suggest - if you are going to take the pickguard off to take a look - to loosen the strings, then take each screw, and loosen it a half turn, then re-tighten it a half turn a few times so you get a feel for how tight they should be. There is a somewhat wide range of torque that these need - it's not an exact science. Then remove the guard, put screws in a cup or something, and look at the pickup connections, mounting screws and springs, etc. Post pictures if you want help with what you see. YouTube, as @Sconnie mentioned, is a great way to get a feel for what you will see / what you will have to look for. However, if you are uncomfortable doing this on a new guitar, then take it somewhere to have someone look at it. Chances are, it's either a screw that needs to be replaced, or just a connector that needs to be touched with a soldering iron. It won't be expensive. Absolute worst case is a pickup died - and your screwdriver work was just coincidence. Still not a big deal or hugely expensive - but that should be covered under warranty.
