Question about Sennheiser PX 100 Consumer Headphones

1 Answer

I am trying to replace the jack on my PX100's. I have a replacement jack and have worked out which colour wires to connect to the various pins. Problem is resin cored solder suitable for other electronic repairs etc does not seem to solder the wires- that is it won't 'run' to solder the lead on the terminal. Any solutions, tips?

See my tip on headphones jack/cable problems. Also sometimes they put on a special coating on the wires. You have to scrape the wire or file it to remove it. Spit is also good at making the solder stick!

DC Jack diagnosis:
1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop

My monitor resolution colour is changed to pink.


Check the data-cable between the computer and the monitor, and try a different cable.

Or, try connecting the monitor to a different computer, to see if the video-card in your computer is not working correctly.
If necessary, replace the video-card.

Colours on your monitor are produced by "mixing" the 3 "primary" colours: red/green/blue in various proportions.

Or, if part of the monitor that produces one of those 3 primary colours has stopped working, then the resulting "mix" will have too much RED/PINK. Fix/replace the monitor.

Monitor changed to yellow colour.... what is the problem...?


Monitors mix the 3 "primary" colours, in various proportions, to produce all other colours.

Mix equal parts of all 3 colours, and you get WHITE.
Mix equal parts of only 2 colours, and you get YELLOW.

So, either:
1. your computer's video-card is not sending the 3rd colour;
2. your video-cable between the computer and the monitor is broken, and is not transmitting the 3rd colour;
3. your video-cable is not TIGHTLY connected at each end;
4. the electronics inside the monitor that SHOULD be producing the 3rd colour have failed.

Try connecting the monitor to a different computer, with the same video-cable. If it works correctly, your video-card is the problem.

Try connecting the monitor with a different video-cable, to see if replacing the cable fixes the problem.

Try connecting the monitor to a different computer, with a different video-cable. If it still is incorrect, then the monitor needs repair/replacement.

Jack plug broken off


Buy a $4.00 1/8" jack replacement from Radio Shack - part # 274-0869, which has small screw connectors that don't need soldering.
Strip about 1" of the braided insulation at the old jack end, which will expose 4 very small wires: Blue, Green, Red, Copper.

Attach the Green & Copper wires to the tallest pin on the replacement jack.

Attach the Red to the shortest pin, and the Blue to the medium pin.

Remember to slide the jack cover onto the headphone cord before attaching any wires!

This works great, I just did it.

Want to replace PX100 wires


Just be careful, maybe try to find a guide to dissasembling the PX-100's - I had a pair go bad that I tried to open up and I mangled them somewhat - of course I wasn't being super careful, nor were they in great condition at that point. There's a lot of you tube vides about replacing the ear buds with other ear buds - it should be straight forward, minus the extra care for taking the PX-100's apart. Any concerns about impedance matching for the wires? Could this represent a degradation of the PX-100's sound if the wires are diff. impedance?

Telephone wall jack


Did the old wall jack work before you removed it?
Are the wires still connected or do you remember where the wires used to go.
If so, then what I would do, is with a phone connected, start disconnecting 1 wire at a time. When the line goes dead, then you know that is one of the wires that you need to use. Reconnect that wire, and mark it, and Keep doing this until you find the other wire that makes the line go dead.
Then you will know which 2 wires you will need to get the jack working.
Usually, the standard color wires that you need for the new jack is Red and Green for a single line phone jack.
Hope this helps.
Good luck.
