Panasonic DP-UB150-K Laser Replacement

Press the eject button to open the disc tray.

Unplug the power adaptor to leave the tray open.

Unplug any other cables.

Remove the 3 Phillips screws from the back of the case.

Slide the top case up and back to remove it.

It helps if you pull the left and right sides out a bit to clear the base.

Unclip the front of the disc tray.

Support the tray while you unclip the front.

It should slide up and off.

Release the latches on the left and right sides plus the two underneath.

Slide the front off and guide it over the open disc tray.

Remove the 3 Phillips screws from the drive lid.

Unlatch the left and right sides.

Lift the drive cover slightly up at the rear.

Slide it back to clear the retaining slots at the front.

With the drive open you should now see the laser unit mounted on rails and driven by a motor.

Gently open the black retaining clip on the laser unit ribbon connector.

Disconnect the ribbon cable.

Unhook the 4 spring clips holding the rails in place. There are 2 clips per rail.

You may need to use a screwdriver to guide the hooks free so be very careful not to damage the delicate ribbon cable.

With the rails free you can now lift them and the laser unit out of the drive.

My "new" laser appeared to be used so I didn't need to remove any antistatic solder points.

A parts catalogue (https://fixpart.co.uk/product/panasonic-...) shows solder across a couple of points on the lower right hand side of the laser.

If these are present on your new laser you need to remove them with a soldering iron. You may get away with just touching the iron onto them but don't be surprised if you need to use some desoldering wick.

Turn the old laser unit over. Remove the screw holding the white motor arm in place. Fit it to the new laser unit.

Mount the laser on the rails. Add a spring clip to the end of each rail.

Insert back into the drive while making sure the white arm on the side of the laser unit engages with the worm gear.

Hook each of the spring clips into place. Make sure the clips are under tension and aren't loose.

You may need to use a screwdriver to push them into place. Be careful not to damage the ribbon cable.

Gently open the black retaining clip on the laser unit ribbon connector.

Insert the ribbon connector and make sure it is lined up and square.

Close the black retaining clip.

Now is a good time to make sure the laser lens is clean!

Gently clean it with a cotton bud/Q-tip and some isopropyl alcohol.

Refit the drive cover by sliding the front in first to engage the retaining slots. Then lower the rear into place.

Make sure the left and right latches are clicked into place.

Refit the 3 Phillips screws

Make sure the button pushers are lined up with the switches on the orange board.

Clip the case front in place. Latches are on the left and right sides with two underneath.
