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. [email protected]

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

    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.

My Marshall MG50 DFX Has an awful buzzing sound that comes out of it after startup.

I would check C22 and C24 the main smoothing capacitors. They can fall out at worst or just have bad solder at best.

My monsoon computer speaker system bass has a constant buzzing sound as soon as you turn it on. The 2 speakers are fine but the bass is consyantly buzzing/humming

if your computer came with a motherboard disc the sound drivers could be on it
you might have to uninstall then restart your computer then reinstall both the sound drivers and the sound card make sure you have both of these devices backed up to a disc before uninstalling
a yellow? question mark means you need to install/update driver to do this
right click to install driver also
click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question mark? Right click to reinstall drivers
click start control panel sounds and audio,volume,advanced,speakers select appropriate speakers also audio you will find 3 drop down lists make sure you have the correct settings there
click start control panel sounds and audio devices you can adjust the volume there also select speaker volume you can change your settings there you can also tick in the box place icon in taskbar
if his does not fix the problem

have you tried this control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or navigate to the device manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable)
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer
hope this helps

I have a djm 400 and it has started producing a buzzing sound through the speakers. I can take the same speaker cables from the djm 400 and hook them up to my backup mixer and the buzzing goes away. What...

Since it works with your other mixer, the DJM400 is probably fine. You have a ground loop.

Make sure ALL, and I do mean ALL... (re-read that if there is any confusion) interconnected equipment WILL BE powered from the same receptacle or source. If speakers or amps are powered from one place and the DJM is from the other end of the room you likely have a ground loop and you can ex[ect buzzing. Run extension cords alongside the audio leads if necessaryy to carry power from where the amps or speakers are plugged in back to the DJM400 and ANY pther connected equipment.

When starting a new cycle no water fills in. It just makes a buzzing sound

An inlet valve can buzz normally...However, if water is not flowing it probably means that the inlet valve is faulty..Make sure that the filters on the inlet valve are not blocked..If they are clear it's probably a faulty valve... Good Luck....Nomess

Buzz sound

sounds like relay chater might be a bad capastor out of spec near the relay i dont have the spec on this tv but some sanyo tv had that kind of sound and it is a bad capastor like 470u at 25 volts in them. Look for a bulg on the top of caps around relay area. Board marking are like c 601 this is not the right number for your set just to let you know sort of what you are looking for the c standing for capastor. Be sure to unplug tv before youtake it apart there is high voltage in the set even after you unplug it.the cap shuld be black or blue with a silver flat top even if they look good still can be bad cant tell untell you test them on a machine.

Buzz in speakers

Not sure what you mean by "buzz" but this sounds like capacitor issues, take it apart if your able and look for caps that are bulged on the top and replace if you find some

Buzzing sound

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.

Speakers have no sound

the buzzing sound is normal for half way, however it does tell you the speakers work, First thing is to make sure the mute is not make sure you have it plug into the out put just and not the mic or input.

The delay is normal as it's designed to create a spacious large room sound. The buzz however, is not. It sounds like the power supply is bleeding into the amp and should be serviced.
