The wire colors from tone arm to cartridge on philips 437 are red white blue and green. the letters on the grado f3+ cartridge are l r g h . which wire goes where?

sounds like your missing the cartridge......the cartridge screws to the head shell, & has 4 wires connected to it...blue / red / green / white.
then the stylus,which is the needle, attaches to the cartridge.
then the hole thing connects to the tone arm, with the head shell.

Yes the correct replacement stylus for a Grado F3 is the Blue stylus. This is the stylus that will fit the older F3 model cartridge.

(1) Yes, wires could be mixed. Here are the codes L = White, LG = Blue, R = Red, & RG = Green

(2) Wires on tonearm base are disconnected.

(3) RCA plugs might need replacemement.

(4) Cartridge is defective.

(5) Plugged in the wrong input of the receiver.

ps, The Bue/white code is Blue +, white -

OK this is what I did: First I soldered a wire each end of a 1.5v battery. I then bared the other ends of the two wires and tinned them. Then I touched the wires coming from under the dash in pairs until I heard the resultant sound coming from a speaker. This then told me the position of each speaker in the car. From there it was just a matter of noting the color codes for each pair of wires and from which speaker they came. My Gregory's Laser KH manual had wiring codes, but entirely different to my vehicle. Also there is no indication of what color matches what letter code! Cheers. Gerry

Most likely you can adjust it in the Service Alignment Mode (SAM).

Press 062596 followed by the STATUS button (upper left). Navigate to "White Tone", press the right key to enter and select "Normal" mode. Set the colors:

Red = 135, Green = 128, Blue = 133.

The "Cool" and "Warm" menus are deltas from the "Normal" settings:

COOL: R -3, G -1, B 5
WARM: R 2, G -3, B -13

Press the "MENU" button to return to the main menu, then the "Power" button to turn the TV off.

It apears the lead wiring contact arrangement is typically generic. Green over Red and Blue over white. I searched Google by images and found the wiring arrangement in a detailed photograph of a Denon headpiece with cartridge installed.
So always remember to draw a diagram before disassembling something.

Red - Right Channel +
Green - Right Channel -
White - Left Channel +
Blue - Left Channel -
