I repaired a PD-8500 4 years ago and at the beginning I thought that buying the IR was the only option to go through the different steps of the TEST mode.
Then I realized that << and >> buttons (available only on the remote) were only need to move the carriage to a given position, which can be carefully done by hand.
What is important is that you can access >>|, PLAY and PAUSE which respectively triggers FOCUS SERVO, SPINDLE servo and PLAY mode...but these buttons are available on the device.
So long story short, at least for me, RC is not (strictly) needed.
Hello friends!
I think that the remote control will be useful in the future.
There are track search buttons on the front panel, but there is no fast forwarding.
And the volume at the player’s output is adjusted using the remote control in a similar way.
It’s also convenient, you don’t need to turn down the volume on the amplifier.
The remote control will arrive, there will be a second series on CD repair.
All the best to you. Vladislav

Hi guys!
Today I finished tinkering with the Pioneer PD -8500.
The remote control arrived and things started to work.
In test mode (electronics turned off), I configured the grid.
A homemade 75mm test disc came in handy.
I did not remove the tray and all the screws for adjusting the planes are accessible from behind the disk (75mm).
There is a rhombus made of sinusoids in the photo; all edges of the rhombus should be as tight as possible.
After exiting the test mode, the automatic electronics adjusted the laser.
Reads discs quickly.
Out of 50 discs, only one jumped.
It was recorded on a computer.
Original discs can be read and rewound with confidence.
Even scratched discs can be read without problems.
Thank you friends that you and your site pushed me to restore this well-made car.
I got a great experience from this work.
DACs PCM 63, this is a great sound from this CD.
Best regards, Vladislav.

Thank you Mauricio!
For such a disk you need a wood cutter with a diameter of 75-80mm.
Such cutters are used by carpenters when they make holes for sockets for electric plugs, with small teeth.
The photo shows a sample.
Could not send video, more than a minute 70 MB.
Great site!
You can now help people and solve similar problems. A laser like this appeared on Alliexpress (500 euros), but installing it requires exactly the same procedure as replacing a laser diode.
With respect to you and to all forum participants, Vladislav.
Great weekend to everyone!
