Question about Philips HTS3450 System
There are several causes for this problem.
1) Faulty DVD drive. Most drives have a dual laser, one for CD, and one for DVD. Check the player with both CD, and DVD. If it reads one and not the other, then it is most certainly a faulty laser. The laser assembly or whole mechanism will need changing.
2) Dirty or dusty lens. If the unit is kept in a dust environment, dust and dirt can be drawn into the machine by the fan. Try using a DVD lens cleaner. If this doesn't work try a CD lens cleaner. (Dual laser - see 1))
3) Condensation. Condensation can build up on the laser lens if the unit is kept in a humid environment. Also, this can be caused by a cold environment. In this case, condensation forms as the unit warms up. In either case, leave the unit in a warm dry environment for an hour.
