Pitch LED not working

This could be the result of pitch adjustments gone awry. Also, you may have both the 45 and 33 1/3 buttons pushed down which cause it run at 78. Here are a few trouble shooting tips and you can find the full manual for the TT at the link posted below:

Record sounds too fast or too slow. 1.) Turntable is set for wrong speed. Make proper speed selection for record type being played with platter speed buttons. 2.) Variable pitch is engaged. Depress quartz button or return pitch adjust slider to center detent position to engage quartz lock. Moving pitch adjust slider produces no effect. If the LED next to the pitch adjust slider center detent position remains green when the slider is moved, quartz lock is engaged. Depress the quartz button to disengage the quartz lock and activate variable pitch. The LED should turn RED

How to tweak the playback speed on Panasonic SL-HM42 turntables


You will need:

1. 1x small Philips screw driver
2. 1x small flat-head screw driver
3. An ear for correct pitch and a little bit of DIY skill!

Step 1 - Remove the wooden base plate

After ensuring that you've removed the the rubber turntable slip mat and securely docked the turntable arm, carefully flip the turntable over onto its lid to expose the wooden base plate, as per below.

Using the small Philips-head screw driver, remove the screws holding the wooden base plate in place, then gently lift the base plate off the turntable.



Step 2 - Expose the pitch adjustment screws

Once the wooden base plate is removed, you will see the speed-controller circuit board on the right-hand side.


To expose the the two speed/pitch-control screws, firstly remove the screw holding the speed-controller circuit board in place, then gently lift the circuit board up on the free side.


Step 3 - Correct the turntable playback speed and pitch

The easiest way I found to correct the playback speed was to flip the turntable carefully back into the original position, allowing the speed-controller circuit board to hang free as shown below.



Next, play a record that you know well and are able to tell when the speed/pitch is correct (assuming you have an ear for correct pitch, that is!), then at the same time using the small flat-head screwdriver, gently turn the speed adjustment screw(s) to adjust the playback speed up or down until the correct playback speed and pitch is achieved (or at least until it no longer annoys you ;).

Turning the screws clockwise (to the right) will increase the speed/pitch, and anticlockwise (to the left) will decrease the speed/pitch.

NB - Both screws allow for fine pitch control, so if the second is already at maximum speed, you can use the first screw for additional speed.
Step 4 - Reassemble the turntable again

When you're happy with the speed of your turntable, remove the record, the mat again & locking the turntable arm, replace the screw holding the speed-controller circuit in place (as per Step 2) and then finally replace the screws holding the wooden base plate, as per Step 1.
Happy listening!

Make sure that the "Pitch" button is turned on (LED is lit) before trying to change the pitch. If it is, make sure that it's not disabled in the settings.

Use the slide on the pitch control to move forward or backward until the dots stay steady. If it is a little old the quartz control won't work as well.

switch on the printer while u holding the pause button and leav it aftre 7 seconds it will print the default setting page.later on you can change it according to the paper setting.

Hope this helps. Please rate my response.
Thanks.

There is nothing wrong with your turntables. The Strobe dots are only a guide to give you an idea of the speed your platter is rotating. Nothing more, nothing less. The pitch control decal is not 100% accurate, it is simply a guide to tell you where the 6% position lies, 3.3%, etc.

As long as the quartz lock function works, and the large middle strobes are nice and solid, and do not move, your fine.
