There seems to be 2 issues with this unit. Usually when the platter speeds up very quickly, one of the IC (integrated circuits) are faulty and needs to be replaced. However, I've never seen the 33/45 lights come on in addition. So, perhaps the issue started with faulty 33/45 switches, and it then caused a short to one of the IC's.

This will have to be professionally serviced, as it is not an easy fix. There are various circuits on the main board which control the drive, so it's a matter of diagnosing which is the culprit. The 33/45 switches will also need to be tested/replaced.

yes, first you have to microwave it, that works

I have a different Sony model (PS-LX-150H) that had a similar problem. I hadn't used it in awhile, and then when I did, I noticed the speed problem.

IF your PS-LX250 is like my PS-LX150, there are small speed adjustment screws accessible from the bottom of the unit. On mine, the two adjustment screws were labeled - one for 33rpm, the other for 45 rpm. Basically I just fiddled a bit with them using a very small precision screw driver until I could verify that I had reached 33 rpm (I used a stopwatch and literally counted the number of rotations/minute after making adjustments.)

Now it sounds right!

If it is a belt drive model it might be that the belt is out of place and therefore causing the speed to be wrong. This might be due to age or wear of the belt. I would look at that before adjusting.
If it is good and you can't see any mechanical fault causing it. Then look for a preset pot (or two) on either the pc board or on the motor itself. They will adjust the speed. If you find two - one will be for 45 they other 33.
Bear in mind the motor might have gone wrong!
