My 1620 has around 50-60 burns on it. Has never given me a problem. I turned it on after not using it for 2 weeks and it reads fine. I'm using shrink , and everything appears to be fine thoughout the entire process of burning on the computer screen. It says "shrink has finished burning", and I don't get any errors. But when I remove the dvd, it's still blank, as if the "write laser" isn't turning on but the drive doesn't realize it. Anyone know the problem. Thanks for any help. I have done searches but can't find any results with this problem.
