Linear tracking turntable realistic lab 2100 ...the arm doesnt move at all? Is there a way to fix it?

i recently bought one with the same issue. it has nothing to do with a turntable belt as the list of useless suggestions state below. you must remove the lid (when open, it should slide out by lifting directly upward), then you remove the rubber mat and metal plate. there you will see a plastic cover held on by 5 or 6 small screws...remove those and the cover. this cover exposes the opening that your tone arm will have to be above to remove the entire plastic shell that houses the entire inner workings. So, with the power ON...use the << button to move the tone arm over the opening (you may want to give a gentle push to the mechanism to guide it along). Once it's over the opening, you can begin to remove the entire cover. there are three screws on the top side of the unit (way down in three holes that were under the platter), then there are a number of screws on the bottom of the unit around the outter edge and one near the center. With those screws taken out, the cover should be able to be removed. Inside the unit, on the left (all the way to the back) is your small motor that spins a small black belt that turns the gears that pull the tiny steel cable attached to your tone arm assembly. On my turntable, this belt had sat so long that it had conformed into an oblong shape and wouldn't spin properly around the two wheels/pulleys. Make sure that you still have a belt there. If not, search the global interweb for one...$5-15 maybe?! I was able to remove my belt, cleaned it up a bit with soap and water (made it slightly pliable and tacky enough not to spin on the pulley/wheels), then put it back on works now. Hope this helps?!?!

It seems like you need to adjust the pitch control. Try looking at the platter strobe light and seeing if it is at the correct speed. If not adjust the pitch control until you can see the dots align. As for the not returning, your automatic motor may be busted.

The wires connecting the play stop & cue have come loose on my optimus LAB 1100. I need a diagram to show me where to hook them up PLEASE!!!

The Levitator is a tone arm "auto lifter" for turn tables and record players that do not have an "auto-return" feature, or has one that is broken. If your needle rides in the "wax trail-off" area of a record it can damage the needle, along with making a horrible noise. It is not enjoyable to have to babysit your records and manually take your tone arm off the record the moment it is done. The Levitator does it for you so you can relax and go about your business. When the record is done the tone arm trips the lever triggering the lifter to raise your tone arm/needle off the record. It is designed with adjustable height to fit any turntable. These are available for sale through Ebay,or please see video to order your own.

Realistic LAB-500 turntable at 33 1/3 jumps to 45 rpm

go to this site?
possibly your capstan needs cleaning? remove the platter and locate the capstan which is usually made of brass? if it is dirty, ie; black use cotton balls and neat alcohol (spirits ) to clean it. also, consider changing the belt as it may have stretched?

Arm does not track properly but skips across records

Just guessing, but it sounds like you haven't counterbalanced your tone arm.  When a tone arm skips, it's usually because there's too much counter weight on the rear of the tone arm.  You want between 3-5 grams, but first you have to calibrate your tone arm (balance it so you know where zero is).  If you don't know how to do this, refer to the Ion directions called "Tonearm Setup" in the instructions.

You need to adjust the downward force by adjusting the counter weight which is on the back of the tone arm. Rotate it so it's closer to the tone arm fulcrum to increase the weight on the arm, like tightening a nut on a bolt.
