The lube... I don't know what it was originally, it 'looks' like Lard (Animal fat - I've gotta remember this is a worlwide site...)
I caused some controversy when i fixed my CDP with WD40 (speay on oil) applied to the pickup arm... to me its fine, but according to some people it'll make the arm stick again when all of the moisture has gone... but, i did it at least
5 months ago, and its still going sweetly... so even if it were to seize up tomorrow, i'd just re-apply the oil, and away i'd go
Thinking more about this, (extra) especially if you want to apply the spray on oil, I would strongly
advise removing the little metal clip (mentioned in my last post) and spraying THAT
... that way you limit the chances (albeit they are very small) of the oil / grease going somewhere that it shouldn't.
Then, just put the metal clip back, screw it back, put the case back together (although don't screw it up)... put in a CD, do the quick track access thing, and then play the CD in the place you normally have the problem... Problem solved? goody goody, screw it up and away you go... Problem unsolved? just have another go?Warning!
When you unscrew the D777, make sure you know where the ESP, AVLS, and Resume switches are (on the back) and Hold (on the lid) are as the little plastic toggles can move around when the unit is undone, because they are normally connected to little micro switches and the screw that holds the laser assembly together is very small and easily lost!!!!!
This applies more to Redshifter...
If you've unscrewed the little metal clip on the rear of the assembly, the laser will 'free-wheel' up and down the arm... you may need at this point a little micro-flat headed screwdriver (I used 1.4mm head) to remove large deposits of the encrusted white goo from the spindle near to the motor as well as lubing the pickup arm!
... hopefully you'll see what I mean if you're brave enough to open up...
If you're not brave enough to take the unit apart, I presume (although don't know) that you can use a cotton bud (Q-Tip?) covered in whatever lube you're gonna use, and smear it on the screw-arm that you can see if you look into the pickup arm... then just run the laser up and down the arm a few times... try that way, its probably less scarey that way... those (in total) 7 screws, with how small they are, are VERY easily lost...
Your call, but... let me know how things go?
