Default WEIRD problem with CD player

Well, Tipping the deck doesn't move the the sled thru any part of that
1/16 inch, unless it is tipped past 90°. So something else on the sled
is moving when it is tipped to cause it to see a reflection.
The closed drawer position, I am sure, is not the issue.
The sled doesn't move to track zero until it sees a reflection.
I can hold it there in a position that otherwise doesn't work (flat or
tipped front to back) and it still doesn't start up.
The side that is loose appears to be designed that way. There is
nothing that would hold it top AND bottom. Gravity keep the top roller
in contact with the rail. A piece as you describe would assist gravity
to hold it in just this position. There is no adj on that roller to
make it bring the sled up. There were no loose pieces in the unit.

I might be able to jury-rig this to make the roller bigger and bring
the sled up.

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 ?
