This post describes and illustrates procedure(s) for cleaning the laser lens and rubber hub in Funai manufactured DVD Drives.
Funai manufactured recorders seldom need to have the DVD Drive's rubber hub cleaned so the rubber hub cleaning SHOULD NOT be performed as a "routine" servicing procedure
If there become frequent instances of read, write or finalizing failures or other disc related errors after extended use
there is a possibility that the DVD Drive's rubber hub (atop the spindle/turntable) is soiled. Another concern is a dirty laser lens.Keep in mind that opening the recorder's case will, or might, void the warranty.THE DVD DRIVE LASER LENS AND RUBBER HUB CLEANING PROCEDURE(S) DO NOT REQUIRE REMOVAL OF THE DVD DRIVE FROM THE RECORDER.
Here is the DVD Drive cleaning procedure for most Funai manufactured DVD Drives:
Disconnect the AC power cord. Remove the recorder's top cover. Release the DVD Drive's rear cover clips, as seen in the first and fifth photos, and lift off the rear cover.
Rotate the DVD Drive's white gear toward the front of the recorder
, as seen in the second photo. This causes the disc tray to extend and the rubber hub, spindle and laser assembly to descend in order to provide cleaning access for these parts, as seen in the second and third photos.Here is a procedure variation for those Funai DVD Drives that do not have an exposed white gear:
Extend the disc tray and then disconnect the AC power cord. Manually position the disc tray about half-way extended, as seen in the fourth photo. After cleaning, manually extend the disc tray to the fully open position before replacing the DVD Drive rear cover as well as the recorder's top cover before reconnecting the AC power cord.
A can of compressed air may be used to remove loose dust. In the third photo the red pointer indicates the rubber hub/spindle assembly. Use a clean cotton swab, dampened, not dripping,
with 91% isopropyl alcohol and very gently roll the cotton swab over the laser lens one time only
. Then use the dampened
cotton swab to gently pick up dust and/or oily residue from the rubber hub, as seen in the fourth photo. The rubber hub is also accessible for cleaning from the front with the disc tray extended about half-way out, as seen in the fourth photo.
Drift the disc tray back into the DVD Drive, then rotate the white gear rearward
until the hub/spindle and laser assemblies rise up to the parked position, refit the DVD Drive's rear cover--taking care to properly anchor the pointed part in the forward slot above the white guide wheel
as seen in the first and fifth photos--then refit the recorder's case cover and reconnect the AC power cord.
Note: The first four photos depict a DVD Drive in a Funai manufactured Toshiba D-R410 from October 2008. Other Funai brands are similar. The fifth photo depicts a DVD Drive in a Funai manufactured PYE PY90DG from September 2006.
