Question about Broan-NuTone RC515 Door Chime Remote Control

1 Answer

Repair at home

I have 4 of your Broan RC515 since 2006 and they all work. One started making a buzzing sound from the speaker which means one of the filter capastors is geting weak and alowing 60HZ to go through. I took it apart and found nothing looking in bad shape. I have electronic understanding but instead of replacing one cap at a time I will just ask you which one would be the most likly one to do. If you can send me a schematic and I will find it my self. Thank you, Robert J Cavasos. rjcrepair@eartklink.net

    using this esr tester while all caps are still connected to the CB won't work will it?

  • rjcrepair Aug 16, 2008

    Thank you for your info. I don't intend to buy a $200 ESR tester just to fix one door bell. I will just buy a new one when this one quits. However if you would send me the schmatic diagram I will be able to pinpoint the most likely and work my way through all one step at a time.

You Need to Buy a ESR Electrolytic Capacitor Tester. Can get one on Ebay ( Affordable ) or Shop around. I Bought one New when I was a Troubleshooter & Making A Lot of Money for abt $200. Largest paper or Metal Electrolytic Capacitors are usually Your Main Problem. Elect Caps Dry out from Heat-age. Capacitor Testers DO NOT Find these Problems I Tried them. More Often I always find More than One Bad ESR Electrolytic Capacitors on All Audio, Intercom, Computer Monitors, Color Tvs I Service. The two leads You put across all Elect Caps on Motherboard or Chassis Instantly Tells if good-bad. I Make and Save Money on all Products I Often service with ESR Problems. Esr Tester Pays for itself Quickly. Takes Disassemly and time to Restore Service But I always Get the Job Done.

    The ESR Tester is Made and will work IN Circuit. No Unsoldering. It Finds all Bad ESR Caps. Don't have Circuit. I Fix almost everything without a Schematic when its Bad ESR Caps. Bending, Weaving, Hum are all the Symptons. OverHeating of Semiconductors & Tubes will Happen with this AC Ripple NOT Being Filtered. If You Locate the Low Voltage Power Diodes Look for a Large Electrolytic Cap Near them or trace wires. 2 Clip Leads and a Replacement Electrolytic Cap can Be Paralled across a Large Questionable Cap with the Same Value or Voltage or in the Ball-park on Capacity. Do this Unplugged. Lo & Behold when You Plug it back in Hum May be Gone. Then Unplug Mount and solder Replacement. I'm Sure You can get a ESR Tester Very affordable & Reasonable if You Shop Ebay-Ham Radio Clubs at the School.

How to connect tv, direct tv box, and home theater together properly ?


Hi Vincent

That would be a heap of detail to go into. Time consuming...

Hopefully this quick pointer might help.

What is HDMI
High Definition MultiMedia Interface

Note the word MultiMedia
This Means....Both HD Video & Sound through the one cable.

HDMI is the latest state of the art connection.
Use this wherever possible. It's made for High Definition
More Convenient

Use a HDMI cable from one device to the other wherever both devices have that port type (connector).

You don't have to pay a premium ridiculous price for HDMI Cables as in the Monster type. Overpriced.
Well made regular brand & Gold pins are nice. Keep them Short.
Long Cables loose quality. 1 Meter is default.

Your LCD TV should have more than one HDMI port for inputting & outputting media (sound & video)

HDMI can be used for INPUT or OUTPUT
Eg OUT to an Amplifier or IN from a device like DVD Player.

On the OLDer equipment you will Have a YELLOW connector. That is used for the Video signal.
The RED is RIGHT AUDIO.
The WHITE is LEFT AUDIO.
Fiber OPTIC cables are a better way to transfer AUDIO than the red & white cables. Cleaner.
But this only works if the 2 devices have an optical port available.

Some New Amplifiers are smart and may require you to select the optical port in the settings instead of the default HDMI.
This may also apply to HDMI Port Choice.
Simply plug the HDMI in first & check.
Use a known source e.g. play a DVD or CD or Radio Reveiver as a signal.
ONE HDMI Port on the TV might be an OUTPUT ONLY channel (PORT) to an External Amplifier (if you wish to use one)

HDMI on external devices will be Outputing video & sound on their HDMI Port
To the INPUT HDMI PORTS on the TV.

Some TV's will fall back to a particular HDMI port on power fail or startup therefore not requiring you to use the remote every time.

External SPEAKERS should have the polarity checked. Eg Red (or marked wire) to the same post on either speaker. This makes sure that the speakers travel forward together at the same time. Pumping sound forward then retracting together....
so they are not fighting against each other.
.......This is called out of phase & distorts sound.

Hope this Helps

Enjoy Your New Entertainment

Tip

Testing your remote controller.


It's something that i have repeated and that is pretty usefull because everybody can do this at home.

Sometimes it's only a matter of pressing on a button and everything is back to normal but it's not always that easy for everybody to get there...

To make sure your remote is fonctional do this test:

Open your radio and put it on a AM frequency, ideally just noise and not on a used frequency.
Approach your remote emitter to make a direct contact to the antenna.
Press on every button of your remote to test them all.
You will ear a buzz sound each time you press on a button.That means that it is fonctionnal. If one button do not make the buzz there is a problem with that button.
That's it!
If it pass the test then the problem might be a matter of programming the remote. Sometimes you just have to press the component you want to use on the remote.

The remote utilise the am frequecy to transmit that's why it does make interference sound. (buzz)
It won't work on FM frequency.

good luck!

Volume buttons not working


Either the mute button was pressed. Press the mute button once. If audio does not return, press mute again to return it to its original status. There could had also been a loose audio cables. Make sure loose audio cables are plugged in. Either the speakers are damaged. If so they need to be replaced right away. There could be distorted audios which means the audio cables or damaged and can easily be replaced. Buzzing audio wrong button on the remote was pressed. Press only one of the buttons on the remote one start with CBL,TV,VCR,DVD,and the AUX.

Audio system buzz with dimmer-controlled track


It may be too late given the date of this post, but the buzzing has nothing to do with the bulbs (usually, dimmers and lamp buzzing are a common problem which is why you probably got the suggestion), but in your case, you have radio-frequency interference from the dimming circuit leaking into the audio circuit. The best things you can do is either minimize the RFI, or separate the audio circuit away from the dimming circuit. Based on what you're saying about the PC input, it sounds like the main culprit is that specific audio wire going between the PC and the sound system - can it be run differently so that its further away from the dimmer/circuit. Are the PC and the dimmer on the same breaker? - If so, maybe noise is radiating from the dimmer into the PC through the power wiring - putting on different breakers could help.
One more note, the best dimmers, in terms of RFI performance, are reverse-phase control dimmers (usually designed for electronic-low-voltage... and be careful because they often get confused with magnetic low-voltage... and those will not help. Without going into too many specifics, the ELV dimmers have a much softer on/off/on/off dimming cycle when compared to standard incandescent dimmers (this is a circuitry thing with a much more complicated explanation), but as a result, they tend to have significantly fewer issues with RFI. They can be an expensive solution for simple problem solving, but the MIRELV-600 should do the trick (again, don't be fooled, the MIRLV-600 is the magnetic low-voltage product, and for what you're doing, won't help).

Powers itself off


Cause
• The speaker wires are frayed or sticking out
of the jack, and are touching the back of the
receiver or another set of wires.

Remedy

• Reinsert the speaker wires, making sure there are no
stray strands of wire and that they are inserted fully.


thank you
