I have a Dell W3706MH tv monitor and the sound just stop working. I unplugged the speakers and plugged them back in still no sound. I unplugged them because it was making a loud buzzing and popping noise...


If possible, plug the speakers into a portable device such as a cell phone, portable cd player or a tv that is equipped with a headphone jack (if speakers have the jack). If not, if the speakers have the red and white, ref and black or black and white male end connectors, plug them into a tv or dvd\blue ray player. If you get sound they are good, and you need to adjust your sound options on your computer. Let me know if this helps\works. Also, not all speakers are compatible with all computers and must have the same sound level equivalence to the device they are being used with. i.e. Ohms etc.

Where the electricity cable plucks into the monitor there is a buzzing noise, and a few times the screen just went black. yesterday it did not come back on. what do I do?


Look for bad solder joints on the 3 legs of the AC inlet.
See pictures here: http://s807.photobucket.com/albums/yy352/budm/Poor%20solder%20joints/
BenQ makes DELL and HP monitors.
Also inspect the caps for domed tops.

Whirlpool upright freezer making buzzing noise and not working


I had a similar problem yesterday. I woke up and the freezer was not working anymore. It would make a buzzing noise and then it would click and shut off. I looked online for some possible solutions. Here is what I did:
I unplugged the fridge. I pulled it out and took off the cardboard backing. I used an air compressor to blow out all of the dust and dirt that had accumulated on the condenser coils. A shop-vac just wasn't powerful enough to pull out all of the dust/dirt. After that, I plugged it back in....and the same thing was happening. It would buzz, and then it would click off. I figured out that the "click" was coming from a starter relay (a small plastic piece attached to the big black compressor). I detached the plug from the relay and then detached the relay from the compressor. The relay was burned out. It turns out this is a common problem with the relay. I replaced the relay for $50 (from an appliance parts store) and put the whole thing back together in about 10 minutes.
I plugged the fridge back in and the compressor started, and now the freezer works better than other. I saved about $400 doing it myself, all in about one hour. And better yet, my wife was very impressed. Not bad for a doctor.

Psp making funny buzz noise and not reading umd disks.


Try a different UMD, it might be scratched. If not, take a soft cloth, and clean the lens. Look on google to see where the lens are located.

Sceptre LCD monitor blank screen, blinking power light


Something has failed or is failing in the monitor. It may be serviceable, but may not be cost effective to do so unless something has just come loose. I'm assuming you have no problems with the new monitor. Your time line is a little confusing.
