Every Kindle Fire HD USB charging jack repair I've done so far (to fix broken or not charging kindle) could have been prevented with some additional supporting solder. I do not know if this is by design or simply defective ones that made it through quality control inspections. I will look at yours for FREE and if it needs the additional solder, I can do it while you wait (as long as Kara is here). Regular fee is $39, but I'll discount this preventative repair to $25. Discount is for prevention repair only, not if your port is already damaged. Please let any friends you know who have Kindle Fire HDs about this offer for me. THANKS!
