Question about RCA WHP141 Consumer Headphones

1 Answer

No power. Headphone will work fine, then stop. Power light on transmitter is off. When I re-plug in the adapter or when I plug the power cable into the transmitter the power light flashes, but does not stay constant. Then the power come on and things are fine for a while, then power goes out again. I assume the problem is with the cheap power connector, but I guess it could also be with the adaptor. The adaptor does not appear to overheat, but it isn't warn either like other adaptors I have plugged in.

On the 15-12-2014 i bought a lloytron 5 in 1 wireless headphone, the manual says i need a 4.5V DC adapter for mains but nowhere does it say the amount of (amps) needed before i buy one,since there are so...

I would think anything over 300 mA would be ok. But I would go for something around 1 to 2 amps.
As long as the voltage is 4.5 it doesn't matter if the current is 10 Amps or a 100 Amps. They will only draw as much current as they need. The maximum working current is only 30MA.

Max consumption current 30MA
Power Supply 2 x AAA batteries

Frequency 85
Transmitting Distance 10M
Complete Voltage 3V
Max working current 7.5mA
System mode RF
Power Supply 2 x AAA batteries or 4.5 DC not included

Set up the transmitter. Wireless headphones rely on a transmitter that sends audio via infrared or radio waves to your headset. Use the digital audio output (coaxial or optical), RCA outputs (red and white) or headphone jack on your TV to connect the transmitter. The connection will depend upon which outputs are available on your TV and/or the transmitter.
Use an RCA-to-headphone adapter. If you don't have a headphone jack on your TV and the transmitter includes only a headphone connection, connect an RCA-to-female headphone connector. This will allow you to plug the wireless transmitter into the female headphone end and then hook the RCA ends into your television's audio outputs. You may also need a 3.5 mm (mini jack)-to-1/4-inch adapter if the headphone plug on the transmitter doesn't match the television jack.
Read more :
Set the transmitter on top of, or next to, the television. For infrared transmitters, you'll need a direct path between the headphones and the transmitter. Placing the transmitter on or near the TV will allow you to take advantage of the clear path you already have.
Plug in the transmitter and turn it on. Charge the headphones if necessary.
Turn on the headphones. Adjust the volume and settings and you're ready to watch TV.

From the manual:

1. Plug the stereo audio cable into the headphone jack of your audio
source (e.g., stereo, TV, CD player, DVD, etc.). If your audio source
has two RCA output jacks instead of a headphone jack, use the
supplied Y cable to connect your headphones to the two (red and
white) RCA jacks.
2. Connect the other end of the stereo audio cable to the AUDIO IN
socket at the back of the recharging cradle/transmitter.
3. Connect the AC/DC main power adapter to the DC IN power
supply socket at the back of the recharging cradle/transmitter. Then,
connect the adapter to an electrical outlet.
Important: This power unit is intended to be correctly oriented in a
vertical or floor mount position.

Bought my headphones in South Africa, now living in the UK. My AC adaptor to power my charger of my headphones is not functioning properly. Could this be caused by the incorrect power adaptor, as it...


Welcome to Fixya. You can check if the power output in South Africa and UK is the same. If you have 110 or 240V in africa check if the Voltage in UK is 110 or 220V aswell. If it is the same it only means that the adaptor is bad. If you can go to a store in UK find an adapter that is compatible with the headphone you can test it and see if it will work.

Thanks for using Fixya.

The LEDs on the transceiver are not lit, thus i have to hold the transceiver RIGHT next to the headphones, to work, do you think it coud have finally gone?

The fact that they work up close indicates the headphone end is working, and the transmitter is retaining some function.

The question is why aren't the LEDs on the transmitter not lit.
The first thing to check is if the unit is getting proper power.
The first thing to check is the power adapter.
If it's not supplying 12V then it needs replacing.
The voltage and current should be marked on it somewhere.
There should be a marking for polarity also.
Any 12V DC adapter that supplies 200ma or more will do, provided the plug fits and the polarity is correct.

If that does not get them working, you could open up the transmitter and look for anything wrong in there like burnt or damaged components, but the power supply is the part more prone to failure

The right headphone on my sennheiser eh 150 doesn't work, Iv'e opened up the headphone and both the cables are securely held in place so its not the speaker, the cable is also fine no sign of any damage,...

I have the same problem, but in my case, I pulled accidentally the cable when it was plugged, but I can't neither see any damage in the cable,plug or headphone; in fact, it looks very strong. I did the same, opened the headphone, but everything's in its place. I've been browsing for two days and can't find any article related to this problem. It would be a shame to have to get rid of these headphones, they sound great!

RCA headphones - nicad or alkaline batteries WHP141

Your wireless headphone unit requires two rechargeable AAA batteries.
Rechargeable batteries are uncharged when you purchase them. Before
you can use the wireless headphones, the batteries must be charged for
16 hours. Follow these steps to install and charge the batteries.
Installing the Rechargeable Batteries
Take care to follow these steps to correctly install the batteries.
1. On the right headphone, locate the battery compartment (1).
Use the finger depression on the compartment to turn the battery
compartment cover counterclockwise to remove the cover.
2. Insert two AAA rechargeable batteries, carefully following the
markings inside to ensure the batteries are inserted properly, with
the + and - ends in the correct positions.
3. Replace the battery compartment cover.
Charging the Rechargeable Batteries
To recharge the headset unit, follow the directions below. Note: The
cradle/transmitter on the WHP141 is not a recharging cradle, although
you may place the headset in the cradle during recharging.
Follow these steps to recharge the NiMH rechargeable batteries.
1. Make sure the ON/OFF switch (2), located on the right headphone,
is in the OFF position.
2. Connect the AC/DC main power adapter to the DC IN power
supply socket (11), located on the back of the cradle/transmitter.

4. Connect the charging cable (10), located on the back of the
cradle/transmitter to the recharging input (3), located on the right

Sentry HO900 headphones

The H0900 should come with a mini-plug adapter. The headphone jack in my TV was deeply inset, so I kinda reversed it. The adapter plugs into the transmitter, then the Red/White plugs, into that, then the long end of the cord into the TV.

Works fine for me. My problem will be posted seperately.

Logitech wireless headphones

Trying re-syncing the transmitter and the headphones. Hold down the power buttons on both until they alternate red and blue blinking, worked for me and now they work just fine. Got that from the Logitech FAQ website.
