Buzzing sound in base unit - Uniden Cordless Phone

Try moving the base unit that the phone cord is plugged into. Keep it away from heavy power users like the microwave and refrigerator. You would also want to keep it away from other transmitters such as your wireless router. Also make sure the base unit is not near your power meter or circuit breaker box. Hope this helps. Good Luck!

We do not advise doing so. The Quinny Buzz seat unit should only be used with a Quinny Buzz chassis and likewise the Maxi Cosi Foray seat unit should only be used with a Maxi Cosi Foray chassis. A combination of the two has not been tested or approved for safety standards and we cannot guarantee the safety of using such a combination.

Hi Charles,

Sorry for the late reply, I'm offline upon purchasing my service.
You have said that you can hear a low buzzing sound before the unit gone to subsequent shutdown and the lamp blinks green(meaning that the unit try to turn on the lamp for consecutive attempts but not generally mean that the lamp itself is faulty.) and the temp led light come on.

As a matter of fact all the information you have mentioned linked to the symptoms you've encountered right now. A low buzzing sound might be caused by faulty FAN inside the unit that trigger the error code (blinking of the standby/temp led light) and turns off the unit automatically due to thermal protection circuit.
However, the technician might be true also that the buzzing sound came from the faulty color wheel. To confirm it, you have to verify where the buzzing sound came from. Color wheel is in front of the lamp assembly. Faulty color wheel can produce the same symptoms you've encountered right now but most of the time, it shows 3 blinking led light at the front panel (Timer, Lamp, standby/Temp).

I would advice you to open the back cover of your unit, fixed the lamp door safety switch with the tape to make it in closed position( if it is on open position the unit will not power up), and then turn on the unit and observe the fans if will spin or not, and check also where the buzzing sound came from before the unit gone to shutdown.
I've suspected that the fault came from the fan based on the led light flashes. Please let me know what you will discover after following the steps above to verify where the exact fault came from. Also, let me know the exact status of the led light at the front panel, (Timer, Lamp, standby/Temp ), which of them lit solid/blinking, it will help us to narrow the caused of the symptoms.

If you see mist in unit and not coming out fan motor in base of unit bad. Four screws in base and fan unplugs

I Had the same problem.
I found out what it was. The buzzing sound came from the AC/DC charger. I changed it and everything is working fine now !
Try with a AC/CD adaptater putting it on the right voltage and check if it's working without this buzzing sound.
Have a good day !

Without power to the unit no sound should be generated. Make sure there are no other connections.

MAYBE you have a wall transformer behind it that is buzzing. MANY wall transformers develop buzz.

Another source is flourescent lights and even some of the low voltage halogens have noisy transformers in the base.

If everything is working as it should - the problem may be with the motor.
Either the starter is starting to fail, or it may have gotten wet. Check for leaks around the base, and be prepared to eventually replace the motor.
If you can deal with the humming, there is no reason to replace it at this time, and there is nothing you can do to quiet the noise.

Thanks for using FixYa!

You're getting electrical interference, probably near the base unit since you hear it on all the phones. Try moving the base unit to the other side of the desk (away from say a clock or radio), or check where your phone wire going to the base unit is running. It may be laying on top of an electrical cord or going across some other electrical device that has a motor.

There may be some sort of electrical device like a mobile phone or something that is near the base unit of the speakerset... try clearing the space around them.. or else it might be cuz of a loose connection... check n reseat all the cables & hopfully the problem will sort out...

You haven't specified where the buzzing sound is coming from, if it is coming from speakers, changing capacitors in the audio section will fix the problem, especially the filters. Now if it sounds like a hissing sound from back of the tv, the CRT base socket is the culprit. It is an easy thing to fix, and the base is cheap, but make sure you purchase the exact same type of base or it will harm the CRT. Good luck.
