Are new, malfunctioning digitizers the norm?

텍스트:

I am new at mobile phone repair, but have been a tinkerer all my life, and repaired my phone twice Optimus S, bad USB port, and volume rocker).

The evo 3d came to me in pieces with a broken glass.  The owner had bought a new digitizer, disassembled the phone, did not have a heat gun, and got stuck.  I removed the old digitizer, and installed, including new two sided tape the digitizer he had purchased from someone on ebay over a month prior.  Upon booting the phone, I noticed it was hard to unlock.  I turned the screen test mode on, and there was a horizontal dead zone in the digitizer, about 1/4 to 1/2 inch high about an eighth of the way up the screen.  So, after checking cables and connections, I ordered another digitizer from a different vendor.  It has a similar issue.  I have tested this one on the side without instaling it.  Looking close you can see a scratched/divoted spot on the reverse of the glass where the circuits come down.  This digitizer was packed as new, with plastic protectors on both sides, in a bubble wrap sleeve, in a bubble wrap envelope in another bubble pack that contained the free tools the vendor shipped, so I doubt it is shipping damage.  The damage also was not on the plastic protector covering that side.  Looking closely, the item appears new.  No scratches, no removal marks, and no adhesive remnants.  I am linking a pic of the damaged area here:[http://i.imgur.com/lFGh8.jpg]

So I guess my question is, is this common when ordering parts on ebay (it was a top rated vendor, I am emailing them now), and if so, what are tips to avoid it?
