Thanks to jmack and other pointing me to the right direction (particularly the right contact in ARCAM). I finally got my DV88+ fixed. I had to pay for one-way shipping back to ARCAM but it was fixed and send back to me in about 2 weeks. The little lines are GONE! I guess the lesson of the story is to get to the right person (Matt in ARCAM in this case) and the problem can be sorted. Thanks jmack!
