Grinding noise


I just chatted with Dell support about this since I have the same problem of the grinding noise on my C1760NW Dell printer. I have it plugged into an APC backup battery which acts like surge protector (unless power goes out then battery kicks in). He said the printer needs more power and that surge protectors and battery backups are not good for this printer since they restrict the power which sends less power to the motor and fuser than what it was designed for. So with less power from the APC backup/surge protector, the motor moves very slow and may not fuser the toner to the page correctly and can cause permanent damage over time. So I plugged into the wall directly instead and the grinding noise went away immediately even when printing 10-15 pages right after plugging into wall, but then the noise came back when I printed a bigger job. So for now I'm letting it cool down for a couple hours and crossing my fingers that the damage is not permanent. So... answer is plug it into the wall directly for maximum power and hope that your printer is not permanently damaged. By the well, Dell support chat was awesome.

Excessive noise in my speakers


usually, it is background noise. Scratchy background noise. Gets worse the louder I turn up the volume. I ran a test on all the channels and it seemed to be the subwoofer channel. I've unpluged the subwoofer but that didn't help. I have also noticed that my receiver doesn't turn up nearly as loud as it used. I usually watch DVDs at a volume level of about 15 on my Denon and that's quite loud. But now, 15 isn't that loud at all. I went to Best Buy where I bought all of this equipment and they immediatly told me it was suge protector issue and wanted to sell me a high-end surge protector. Perhaps they are right but not sure why it began rather suddenly. Probably not helping you much.

Taco timers and Surge Protectors


Do they run at the same time? The two items consume
a lot of power. Check the voltage when they are turned on. If the voltage is below 90 Volts. The power surge at your Taco is great. Then, the surge protector could not
handle the current inrush that's why it's blown off. You
must install a surge protector that can handle the Taco
current inrush.

My JBL Control 10 speakers cut out simultaneously. I have the speakers/receiver/lcd tv/xbox 360 all plugged into a giant surge protector and in the same outlet (no other option) and everything still works...


Hiya, I am guessing that the fried wires were the inputs to the speakers? If thats the case and they are damaged, then unfortunately both JBL could be blown, most likely preamp damage. Try taking them away from the system and using a completely different source like the output from a CD player/MD/ even video with a new cable. That will tell you if it is the speakers or the reciever you are using.

If they are damaged, you will need someone with electronics abilty to repair. If the input wires are damaged, there is a good chance there will no warranty, however discuss with JBL, then decide where they go for repair.

All the best

After my house was it by lightning my Onkyo


If your receiver was connected to any power source and that power source was not a surge protector strip there may be damage to the receiver as lighting travels. Another thing to consider is the fact that many people will put their equipment on surge protectors but the cable is still connected to the TV etc...This is just another avenue for the lightning to get into the home and blow up your system. I always disconnect any cable from my computer and TV. The power source from the wall is also unplugged when there is a storm just to be sure. Surge protectors are limited in their use as well. I don't believe they can take too many lightning hits. It is best to change them out.

Speaker crackle


HDMI is a High Definition Multimedia Interface and has the capability to transmit both AUDIO and VIDEO all in one cable. Your setup right now is transmitting 2 audio frequecys (L/R stereo RCA and HDMI) into the Denon inputs. Not necessary! I would recommend eliminating the red/white audio cable from the direct tv box to the Denon.

After doing such, your receiver should be able to process audio/video signals appropriately. REMEMBER to unplug all POWER CORDS before reconnecting any speaker/audio/video cable, as it may cause a small electrical surge and fry a micro component in your system!

Sub woofer making a screaching loud noise when powered on


The pop from other electrical items makes me think it's a ground problem but I am do not have a clue as to what type of setup you are running over there. Did you try a surge protector?Is it 110volts with a seperate ground wire?
Have you tried running a UPS?
