There are several things you need to check, Check the lubrication in the bushings on the platter and make sure it is not sticky. You can clean it with 91% alcohol and relube it with silicone spray. The other things are all electronic tests to see if components are bad. There are several electrolytic capacitior on the power supply board and these need to be tested and probably replaced due to age. This is a soldering type of repair. You need test gear to see if they are bad. The last thing to test also on that board is the voltage regulator.

RPM high n everytime i shift then car speed keeps on going fast n i dont even step onto the accelerator so i can add more speed of stay on a constant speed

You have to change your clutch kit. I just had this issue and after changing it it runs smooth again.
Just to confirm, you shift gear up, your engine roars (goes up to 4000 or more RPM) but doesn't gain speed until few seconds later after the RPM is back to normal.
If so that's the clutch plate causing the issue.

Anyone know what dots on the platter should be still at 33 or 45 rpm, never been told or shown, tried adjusting them manually one day, now i have dips on both pitch controls and its not helping my cause

The large dots tend to be for 33. Records will not maintain constant speeds as they play so you have to get it the nearest you can. You can keep adjusting it, but it's only needs to be done if you notice the loss of speed or increase.
There are 4 sets of dots due to the variation in power. 50 or 60 HZ. You select the dots for your national grid output.

Failed (Error code: WCD44-RSI)

Oh I know! Pick me, pick me! (Lol!)


You mean WCD-44-rm5?

Spindle test. Actually finding out if the spindle motor is spinning the Spindle, at the maximum spindle speed in RPM's, the spindle is rated to spin at, (At maximum spin up)
Also a few other quick tests.


!O_O!

Basic construction of your harddrive. IDE (PATA) or SATA;

Inside the harddrive's case are;

1) Platters: They resemble CD or DVD disks, and are usually made of metal, or glass.

The Platters are coated with a magnetic medium. (Ferrous substance. Think Iron )
There may be 3 to 6 Platters, or more, inside the harddrive case. They are coated on both sides with the magnetic medium.

2) Spindle, and Spindle Motor:
The Spindle is part of the Spindle Motor. It is the shaft of the motor.
Comes out of the Spindle Motor, and the Platters are attached to it.

The Spindle Motor is designed to spin the Spindle (Shaft) certain Revolutions Per Minute, when called upon.
The maximum RPM's it will spin is stated for the harddrive unit.

Older harddrives were rated at 5400RPM.
(Slower before the above time period)
Newer harddrives usually spin up to 7200RPM.
Gamer type harddrives may spin 10,000 or 15,000 RPM's.

http://www.behardware.com/articles/727-1/western-digital-velociraptor.html

3) Read/Write Head:
The magnetic medium on the Platters, is arranged by a Read/Write Head.
There is a Read/Write Head above, and below, every Platter inside the Harddrive.

The name indicates what the Read/Write Head does. When the Read portion of the head is activated, it reads what is ON the Platter.
When the Write portion is activated, it writes TO the Platter.

(The magnetic medium is arranged, by the Write portion of the Read/Write Head. It is arranged in a series of 0's and 1's.
0 being OFF, 1 being ON.
This is changed into Machine Language the computer can use )

4) Actuator Arm:
The Read/Write Heads are attached to an Actuator Arm.
The arm swings the heads back, and forth, across the Platter's surface.
(When called upon it can swing the Read/Write Heads back, and forth, at HUNDREDS OF TIMES A SECOND. -> HUNDREDS )

5) The Actuator Arms are attached to an Actuator Motor.

The entire assembly above is encased in a.....case.
It is assembled in a Clean Room. A room that is 99.9 percent dust free. The outfits the assembly technicians have to wear resemble a NASA space suit. They have to walk through an air corridor, and be b-lown off by air jets, before they can enter the Clean Room.

The harddrive's case has a small filter on it. This helps keep the atmosphere inside the harddrive, as it is outside the harddrive, but with NO moisture, NO dust.

On the bottom of the Harddrive case is an electronic circuit board. Controls the hardware inside the harddrive case, and is connected to the motherboard.

The Spindle test is to see;
1) If there is any axial, or horizontal runout. That is to say if the Spindle wobbles, so to speak. If so the Spindle Motor bearings are bad.

[Platters have to stay Dead Level. The Read/Write Head is spaced off of the Platter, by about .00003 of an Inch.
(3 hundred-thousandths)
May be closer my figures could be off,
In comparison an average human hair is .003 of an Inch thick.
(3 Thousandths)

Due to the speed the Platters spin at, and the closeness of the Read/Write head to the Platter, the Read/Write Heads actually float on a cushion of air, when the harddrive is active.

When you hear or read the term 'Head Crash', it means one, or more of the Read/Write Heads, has touched a Platter, (Or Platters), and wiped off some of the magnetic medium ]

2) Spin up speed. How long it takes the Spindle Motor to spin up to the required RPM's. Actually, how long it takes the Spindle Motor to spin up the Platters, to the desired RPM.

Doesn't reach the RPM goal? Spindle Motor bearings are probably bad. (Or a failure in the electronic circuit board, on the bottom of the Harddrive. Doubt it. Usually just fails altogether )

A) http://computer.howstuffworks.com/hard-disk.htm

B) http://www.youtube.com/watch?v=s8-pHHv9LYQ&feature=fvwrel

Point?
The test indicates your harddrive is going bad. I would (Pronto) copy off my personal information. (Disk/s, thumb drive/s, storage on the internet, etc)

How do you put on a drive belt?

Hi Janie, Thanks for your question. To replace a drive belt.
1, Remove the rubber platter mat to expose the platter.
2. Put your thumb and forefinger through the two round holes and lift the platter off. You may need to give the centre spindle a light tap (whilst applying upward pressure) with a screwdriver handle or some similar tool that will not leave any marks or damage.
3. Remove the old belt and wipe the platter pulley and motor pulley with an alcohol swab to remove any old belt residue.
4. Place the new belt around the platter pulley making sure t is sitting flat without any twists.
5. Flip platter over the right way up. There are1or 2 larger rectangle shaped cut outs in the platter.
6. Through the cut out pinch up the belt and slip a finger or belt hook between the platter pulley and the belt gripping the belt ready to fit over the motor pulley.
7. Align the centre hole of the platter with the spindle and place platter back into position keeping a grip on the belt.
8. Slip belt over motor pulley and give the platter a light clockwise rotation to ensre the belt is riding correctly.
9. Replace the rubber mat and then run the turntable to ensure correct operation.
Job done.

Note the new belt should sit on the platter pulley and not fall off when the platter is flipped over the correct way up.

When changing speeds between 33 and 45 always be sure that the platter is turning to ensure proper placement and rpm.

All the best, John. [email protected]

I can't get my Marantz 6025 turntable to turn? It has not been used for many years.

As you Marantz 6025 is a belt drive type turntable, the most possible problem is that the belt has been cut or destroyed. You can check it out before order a new one.
Here is the replacement procedure. Pull up the rubber mat, pull up the platter and find the belt. If the belt is removed from the platter, replace it with the glossy side outward. Pull the platter back at the original position. Turn until one of the 2 big openings come over the motor pulley. With your finger place the belt from the platter at the motor pulley. Pull the rubber mat back. You are ready. Here is a schematic for all the above:

Marantz tt2200 mc or mm?

Not sure on the answer to this, but I would recommend using a MM cartridge. Simply because of the cost involved in reproducing the proper sounds utilizing an MC cartridge, as well as the maintenance involved. In addition, the cost of an actual MC cartridge. Expect to spend about US$200 for an average one. For that kind of money, you can get a top of the line MM cartridge. Plus, they are hard to source, especially when the needles break.

Hope this helps some.

Braking not working right

Well, does the platter spin at a constant speed (33 or 45 rpm), or does it spin super fast? If it spins at a constant speed, and it just wont stop, replacing that pot should do the trick (VR201 can be purchased HERE). You can attempt to replace it yourself (soldering skills are required), or just buy the part, and have a service tech replace it for you.

If it does not solve the problem, then the issue is with one of the IC's (integrated circuits). This is a more complex diagnosis and repair. But try replacing VR201 first, then taking it from there.

Good luck!
