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 AND........it works now. Hope this helps?!?!

I had the same problem with my 2100. I broight it to Radio Shack in Wildwood Florida, I live nearby, an it cost $21.40 to replace the belt and clean the track for new grease.

Concerning the Realistic Lab-2100,an excellent explanation on how to remove the plastic shell by Cory Gleasor which I have followed to the last screw! Trouble is the tone arm on my deck refuses to move at all power on,off or otherwise.Which means I am unable to remove the shell as the tone arm won't move to the opening! Does anyone have any ideas please.Thanks.

I have had one of these turnables since the mid 80's as cory greaser said you have to remove the cover to gain access to the innards. The tone arm is mounted on a buggy that runs on two rails the grease on this buggy degrades over time and becomes very sticky. You need to clean all the old grease from the rails & the bottom of the buggy. Then renew with a non-sticky silicone grease.
