Default Samsung DVD-709 disc speed

Hi all,
I have a Samsung dvd model DVD 709/XSA

DVD will play although it seems to have a jump or pause in the picture/sound
every few seconds
This coincides with the servo motor disc speed slowing down, i can hear the
motor
revs change as if it gets to correct speed then slows down and repeats this
over/over

Anyone with any info would be appreciated

Are these motors interchangable between different DVD players ( not same
make )

thank you

Does this occur on *all* DVDs' ?
It might be something simple like dirty/scratched DVDs' or a
very dirty lens on the laser.

Yes seems to be all , have tried 6 different dvd`s

1st dvd was a brand new one

Have cleaned lens, and tried more dvds but still does the same
Seems as though the motor or speed is ramping up and down
and not holding if you like at the top speed

I would try to clean the laser first, and check for binding of the sled
motor/gears. A lump of dust or dry grease on one of the gears that
moves the laser across the disc could have that effect.

Samsungs have a bad reputation for laser pickups going bad.
