Does not read CDs and DVDs or chokes | Mechanics | After changing the optical unit, the focus was not activated, the cause was bad contact in the flat cable in connection with the main board, after cleaning the contacts on it, the focus started working again, however, when it was in the DVD after a period of 10 minutes, the DVD the image started to choke, and this always happened within 10 minutes in the case of this DVD (disc) if you put in another DVD disc it would always skip at another time, for example it would always skip after 25 minutes, this showed that it was a mechanical and not electronic problem, the cause was the optical drive guides that were out of adjustment, because after changing the unit I didn't adjust them, as I didn't realize this, after aligning the guides the DVD started reading DVD discs again normally. | Bili |
