Re: Speakers have hissing noise coming out of them
Hook a graphic equalizer between the piano and speakers, and turn down all sliders above 8 kHz. Since the highest note of a piano is 4186 Hz (4.186 kHz), you'll still hear all the notes but cut the hiss. If the hiss is coming from the speaker's power amplifier (in which case the equalizer won't help), turn down the speaker volume and turn up the piano volume. Live instruments generally need some doctoring to sound good through high-quality stereo equipment, as they only produce a limited range of frequencies whereas good speakers reproduce a lot more - including hiss.

Pull up the menu screen and scroll through until you come to FM transmitter. Select FM transmitter and scroll through to select a radio station(88.1, 89.1, etc). Select the station. Now, tune your vehicle stereo to said station. Enjoy.
Hi, cases like that always comes u. Earlier you said just replaced it, that's not too good for anew monitor speaker.
You could test the fuse inside the speaker if it's still working, might be power fluctuation that might have caused it to blow.but you need to test it. If it is the fuse,fine! you can replace it, it does not cost much to replace.
Also if i can recall,most new stuffs always comes with guarantee with it,right?. I would suggest you could take it back and get a replacement, and i guess if they see it,since it is on guarantee,they can fix it for you without even charging you a penny.
I have a Korg C-15s and also experiencing loud crackling sounds when I turn it on. The problems seems to be either the sliding volume control or the amplifier itself. Honestly though, I believe the issue is the volume control. I opened my piano to get a closer look and attempted to clean the contacts on the volume. Unfortunately after cleaning the contacts, the crackling sounds became somewhat worse. After I turn the piano on, the volume control is generally rendered useless......volume set to low volume and the noise is quite loud and other times the volume control is set high and get very low volume crackling noise. No real consistency. The noise does diminish after a few minutes but so does the piano sounds to an inaudible level. There were a couple of instances where I turned it on and surprising enough, no no noise and perfect sound. For these reasons I believe the issue is within the volume control and not so much the amplifier. I have an electronics background and noticed that the volume control is very unique in design and is not something that can be substituted with another volume control from other sources.
My recommendation is to check the sound quality of the audio from the RCA L/R audio outs on rear of the piano by connecting to a stereo receiver. If it sounds fine you're in luck. If the crackling sound does not diminish after a few minutes like mine does, I would suggest disconnecting the internal speakers and using the audio out only. You can connect a pair of studio monitors or high quality computer speakers, preferably with a small subwoofer to deliver the full audio range and deeper tone of a real piano. I'm currently using a basic pair of Logitech computer speakers and is quite acceptable until I can afford a high quality set of monitors or relocate my piano closer to my high quality Yamaha receiver.
I have a pair of BX5a monitors hooked up to a video editing suite. One
of the monitors is off. They are powered to a working electrical
supply. They are driven off a Mackie DFX-6 with a 1/4" unbalanced
connection. No blue light on the monitor, no sound or hissing on
Not sure i can help with the led problem but i just fixed a hissing problem with one of my BX5a monitors. It developed a hiss when on (both tweeter and bass) and a very loud thump when switched off. I found a slightly swollen power filter capacitor on the internal board. They are the two biggest black capacitors, labelled as 25v 6800uf. Only one of these was bulging. The tops of these should be totally flat. The indented X on top of the caps make any bulge easy to spot. Worth opening it up and having a quick look. I could only find 35v 6800uf caps at my local electronics store but they did the job ($3 each). I swapped both out and it's now working great. An easy DIY fix, just be sure to always have the power cord unplugged before you put your hands anywhere near the guts of the thing. Hope it helps.
I had the same problem for the longest time with my set of Logitech 540 5.1 speakers. Turns out the solution was pretty simple. All I did was open the Master Volume controller and mute the Microphone. Hissing went to zero. Sound is great now.
