My philips170b lcd can't produce sound.It doesn'tproduce sound on anytime. model;philips 170B

mcdevito75 here, Sounds like your moitor is burned out, I would take the monitor to a Staples, Radio shack and have it tested. Monitors are just like a light bulb and do go bad or burn out.

Usually for the volume bar to just pop up something would have pressed the volume button. It is possible that the volume button has gotten a malfuntion on it and this makes it to pop-up all the time. Try getting underneath the volume button cleaned. But preferably this should be done by an expert.
Hope this solution has been helpful?

if u'r eng. change the crt base in video board or u'can set u'r defocusing prob by EHT focusing section

From the manual I found, this model does NOT support ANY audio connections.

But if yours does have these ports, I would suggest they are not for a headset, but for connection to the _PC_. I would suggest your model monitor has built in speakers, and the green port is the INPUT from the PC Speaker output. The pink goes back to the PC from the MIC which is built into the screen.

sound like the power supply or the monitor bulb is going.
try the monitor on another PC if you can get one, if it works, then you have to find ou the manufature of the video card and get the driver.

hard drive failed or you have a cd in or floppy in the drive.

Does the screen go to the top of the page by any chance if so their is a possible cable problem that links your PC to your monitor, to repair this you must take it to a electrical repair shop, its quite a small job and your screen should be back up and running in no time, it happened to my packard bell monitor aswel and i managed to get it repaired.

Hope this answers ur question John.

Crackling sounds are probably due to a couple of capacitors failing due to age, on the control board. (They can also "whine"). Should be easily replaceable by any experienced technician. Not a difficult job.
