The image of LD-1100 was disturbed

It will stop for a moment
And it cures right away

On a CLV disc it happens 1 or 2 times
It certainly does not always happen

Where is the variable resistance of the board to be coped with?

I think that it is PC board VR 201
Is it the correct answer?

Intellectuals, please

I solved it.

To be someone's power
I will list it.

Basic item
①HE-NE Laser & Mirror Cleaning
② Adjust substrate resistance VR4 or VR2

VR2 has returned to a wonderful playback image

These are effective for LD-1000 (JAPAN) & LD-1100

Dirty

Before and after construction

It is effective for plain touch which is innocent (unpainted)

Nail remover (acetone blend)

It will melt away many years of dirt

Caution) There is a fear that letters will peel off

Nail remover → plastic wax → completion

It turns into very good white

Very nice.
Sometimes nail remover is too strong but the player is not an expensive one and it came out really nice.

Enjoy that player for years to come.
