I have the same problem with a FISHER tangential turntable. Press PLAY and it goes to the end of the record without lowering the arm then returns and stops.

You have sensor problem or sensor amp.

Without any repair began to work with this problem plate.

"normal" plate

from the very beginning was checked the contact in trimming resistors, a few turning back and forth.

I am not sure what the problem seems to be, the OP post is confusing, however, if the real question is: why his automatic turntable does not correctly identify a particular LP,
then the answer is that all automatic ones have LPs that do not like, and the sensor adjustments have to be set up accordingly.
For instance, one solution coming from factory for some Technics turntables is to to provide a green matte to be placed upon the rubber (black) one - this, according to Technics, improves the detection of an LP (in particular the coloured ones) and avoids the needle to drop upon platter and get damaged.

If only the start is wrongly identified maybe this is your problem.
If the pieces are not correctly identified (including the first one) then you may have a displaced position, which is correctable by adjusting the string of the arm (lots of tests needed).

And it may be that some players cannot be set to accept eg 45rpm with 12", only with 8".
