Hi, this is the second time I attempt this fix, the first time it worked perfectly. The problem is that with this second machine there's a couple of pixel lines that have not tickled back to black even though I have been patiently going over them for quite some time (2 rounds of 10-15 min) is there anything else that I could try or should I just go on over the same area until I see something happen? Thanks in advance
