Default WEIRD problem with CD player

NO, I have pushed it to be sure it is all the way in.
The tip is from side to side so gravity is not at work here. A

front
to back tip will not cause it to operate.

Also, it will only CONTINUE to play in any position once play is
started. If I tip it to read the TOC then lay it flat it will not
start playing.

I HAVE discovered something else.
The sled rides on 2 rails. one side has a sleeve on it, the other
rests on a roller. It will move up about 1/16 inch on that side.

If I
try to start it while flat AND holding that side up it works. Once
started, I have to let it go so the sled can move and it continues

to
work.
Since that is not giving me a 45° tip, it does point to the lens

or
something inside being too far off to see the reflection in its

normal
position. Since it comes back at a 45° tip I have to think

something
inside is loose rather than the lens gimble as that only seems to

move
in the plane of the CD. HOWEVER, there isn't anything else in the

assy
that moves except the lens is there??????????
THEREFORE, it has to be the lens gimble, RIGHT?????????


Weeeeeelllllll ... Not necessarily. Firstly, just because you have

manually
pushed the tray all the way in, that still doesn't say that the

whole
loading process has completed correctly. There is often continued

movement
to complete the loading cycle, after the tray is fully home.

Sometimes, for
instance, a tray lock slides into place, finally working a switch,

to tell
the micro that loading really is complete. However, leaving that

aside for a
moment, I think that you can be pretty sure that a 1/16th inch of

vertical
play at one of the slides, is not correct. Are you absolutely sure

that
something is not broken or displaced or missing from the mech at

that point
? It's not uncommon for there to be a phosphor bronze finger

attached to the
laser assembly, and resting under the slide rod, to take out just

the sort
of play that you are describing. If it definitely works under all
circumstances with the deck flat, but that side of the laser lifted,

then
logically, that must be where your problem lies, right ?

All this talk of CDP-302 got me to finally repair mine. Disc tray
pulleys all gummed up with that 'wonderful' Sony oil that turns to
peanut butter. Clean / lube and runs properly. I forgot what good
servos that machine has. Thanks for the reminder.
