Default What does this symbol mean, in a Philips CD player service manual?

Is it a special resistor?

Most of the resistors between an IC's power supply pin and the supply rails are drawn this way. With the "!" and the 2 parallel bars.

Any idea?

The symbol generally means that the resistor is flameproof.

Thank you

Do the 4 grey resistors look like flameproof ones?

No. Look for resister #3205. It might be one of the blue ones.

From Philips:
"Safety regulations demand that the set be restored to
its original condition and that components identical to
the original types be used.
Safety components are marked by the symbol ."

Many other components are often marked with that symbol, like diodes, optocouplers, trafo's, coils... and not only safety resistors.

The blue ones are caps. The 4 grey resistors have the same symbol in the service manual.
They aren't the #3205, but this one is difficult to access and to photography

Default What a mouthfull

It means that to retain the standards to which the safety certification was issued, the same part must be used for replacement. It must also be fitted in the same pysical position, with the same accessories: eg sleeve, stand-offs etc, where used.
This can sometimes mean that the resistor is flameproof.

Yes, this symbol isn't only on resistors.
But I haven't found this text in my service manual

Thank you!

Philips always draws resistors in different ways on the same schematic because of diferent wattage etc. Somewhere in the manual you will find a note explaining which one means what. Have you got the whole service manual or just a part of it ?

I've got the whole service manual.
The resistors with a ! are 0.66W
