It's been *many* years since I played with DVD players (when they became uneconomical to repair), but I recall many lasers being shipped with a solder blob jumper on the ribbon cable to prevent static damage. The blob had to be removed after the laser was installed. If the laser doesn't work at all, see if there's a blob jumper on the ribbon. There also might be a trimmer adjustment on the kapton ribbon, but I wouldn't try adjusting that until every option is exhausted. I recall tweaking that a bit as the laser got older to improve readability, but pushing it too high would also damage the laser diode IIRC. |
