VZ 2000 turntable problem

Hello

I’m in Fance and I recently bought a Sharp VZ 200 in pretty good condition for its age but the turntable was not working already. The tape, the tuner and the AUX are OK and the 4 speakers working.

When I first tried the record it didn’t work, I stoped it and start a few ties, open close the door, I saw the record turning verry slowly for a few second once but never again, I wasn’t able to move the tone arm using the buttons but I when I was playing with the other buttons (side A/B, repeat…) I could see the LED (green and reed) switching on and off.

So I order the 2 turntable belts,I'm almost certain they are the right ones the drive belt was sold on Ebay as a sharp VZ 200 drive belt and I order a square 4" tone arm belt through an american specialist website (forgot the name). I downloaded the service manual and started dissambling to give it a good cleanup and try to restaur it for my best friend 30th birthday !!

I didn’t break anything at least I think so, I totally dissambled it all the way to the speakers, cleaned the electronic with contact cleaner, polish the plastic etc…

The turntable belts were both seriousy damaged so I was confident it would be easy restauration ! I finished reassembling today and didn’t break anything, I think so ! But it still won’t play a record, and this time when I play with the buttons (side A/B, repeat…) the green and red lights don’t respond ???

So I took off the turntable again but left it pluged and notice that the gearbelt motor (the one with the tonearm belt) was slowly spinning but wasn't moving the belt… I took off the tone arm belt and the motor start spinning at a normal speed (I guess). I probaly have to seriously clean the little wheels systems after the tone arm belt, it’s not easy to turn even by hand.

I stopped there today I needed a break ! I have a friend who understand all the electronical schema of the manual so he is having a look on possible reasons for those problems but do you have any idea on

why this turntable is not spinning ?
why the green and red lights doet work anymore ?
how to fix the tonearme system ?

I was hoping by trying to think logical that when you start the turntable it first put the tone arm to a rest position before starting to spin the record and allows you to use the buttons ?? makes sense ?

Thank you verry much, hope you had a nice Christmas !!


PS : I also have 2 VZ 3000, both with problems but différents, I’m supposed to make one working (for me this time) but if you know that I can find spare parts in those that can fix the VZ 2000 let me know.

I didn't read all what you described about the problem. We can help you solve the issue. The link below will help you replace belts.

This instruction will help you a lot.

Sometimes, belts that are too tight will cause motors to spin more slowly. That's just an idea of what might be wrong regarding the belts.

I would suggest reading all the threads in this tech section regarding the VZ units. I am confident everything has been covered.

Also, check the downloads section for VZ service manuals.

check if power is getting to motor
There is a small switch on the door to stop the motor when door is open
It could be broken i have seen this before
the little arm can break from age
I have just started parting out one if you need parts
Cheers

Hi guys and thank you for your help !

I do have the service manual and the strip down instructions, I have already finished dissassembling and reassembling with a good cleanup and a rebelting of the turntable. I did almost break the switch you're talking about nikonfoo but I saved it and it seems it's working.

Here is what I plan on doing next

check the turntable drive motor to see if it receive power or not and if it's working with external power directly apply
check the PCB for cracks
clean up the wheels system after the tone arm belt probably grease the inside of the axes
check the pulley and wire system of the tone arm and make sure it's in correct position

Am I doing things right ? any ideas or things I could forget ?

Here is a picture of the VZ when I bought it



This is when I finished dissassembling





Sorry I didn't take pictures after reassembling the first time but it's really nice and shinny all polisshed with all the knobs... almost perfect !
If only the turntable was working !

I have the service manual and i also used the strip down instructions of Kev and order the SM 4.0 drive belt on turntablebasics.com
I might be wrong but I thing the problem is after the belt, I hope after a good cleanup the tone arm will be free to move again and the turntable will magicaly start after that !!!

Are you sure those are both same unit. One is American version (black) and other looks Europe. (Red n blue)

By the way the top functions buttons are usually an issue with these and may need a verygood cleaning.

My bad, upload wrong picture I forgot I downloaded pictures to show people how it works, here is the good one

Check if the turntable motor is getting power. There are cases where the main turntable motor has gone bad.

Both motors can go bad. In one of my VZ the pulse advance circuit went bad, so the tone arm won't advance on the record groove and jumps back to the beginning.

The pulse advance small motor moves the tone arm to the center or the record as the record spins. So that motor spins fast in the beginning to move the tone arm and land on the record, then it spins little by little to advance the stylus on the record groove.

Once you check the power on the main motor leads we will get some idea. Trace the 6 wires from the main motor to the PCB and see if connections are okay.

Cracking of the board happens only if the whole unit was dropped or smashed somehow.

Tone arm movement is linked/activated with the small motor rotation.

It has been a while I played with my VZ2000, 3500 and all so I forgot a lot.

Our members here knows more about VZ2000, so they will have better suggestions.

I would also check switch at bottom that powers up turntable portion

Thank you all for your time and ideas I don't have the VZ at my place because I have a friend with an "electronic workshop" at his house. He sadly don't have the time to help me a lot but I have all I need there, I'm going there tonight and hopefully I'll come back to you with some good news !!

Verry happy to come back to you with a working turntable and it was all my fault !
I played with the tone arm wheels system by hand to understand how it was working but I went too far and actually bended the switch ,it was during the first day of the restauration... I somehow with a lighter rebend correctly the switch spend 30 min looking on the floor for the little copper piece that fell off and put the switch back in position. The thing I didn't notice was that now the tone arm system had gone too far after the switch that indicate the rest position !

Here is a picture of the situation before fixing the arrow point a piece of the wheel that should be on the right side of the switch but there it's not !


So I simply took the switch off turn the wheels backward a little bit, rebelt and miracle I have a fully working VZ 2000 !




But my work is not completly over yet ! The four light indicators of the record (repeat side...) don't work, all the commands respond perfectly but the lights are not working ! Any clue ?

Happy for you! Nice to know the turntable is working now.

Never seen those indicators not working. That is very strange.

So I think the problem is there, my knowledges on those things are verry limited and quite old but I have to try fix those lights !

So correct me if I'm wrong but the lights I'm talking about are the n°1 on the picture, the buttons should n°2 then and I've identified Gnd with n°3.
My best chance is that somehow the LED are simply dead, so if I check between Gnd and each of the LED if I receive power when I press the corresponding button I should find out ? Am I dreaming ?

If it's not that simple or an evident broken wire that I haven't seen yet, I'll be happy to have any suggestion by peole who understand diagram better than I do to give me leads on where to look for a broken wire or a bad connection that would stop those LED from working and only this !

Once again thank you guys for your help and support, we're almost there !

so lucky it didnt snap the plastic arm on the switch
Great stuff
Nearly there

Are any of indicators lighting? Not even side A? Very doubtful that all indicators are out.

None of the lights are working but when I first bought it they were ... must be a beginner mistake during restauration... hopefully I can fix it but at least my friend would have his first almost fully restaured VZ 2000...
I'm gopiing to work on it tomorrow, D day is new year eve (surprise 30th birthday party) ... fingers crossed

Next thing I would try is cleaning the switch board for these operations
