I have a Philips TV that is about 4 years old. Everything was fine with it last night. Today, I was cleaning and used the vaccum dusting attachment to clean the back of the tv (it was not turned on) and behind the entertainment center. After I was finished cleaning, when I turned the tv on, there was a picture, but no sound at all. The only difference that I noticed, besides the silence, is that "mono" shows on the screen everytime I change the channel. The closed captions work and I was reading in another person's post that that could mean that mute is on somehow. I muted and unmuted with the remote, but nothing changed. I plugged headphones into the headphone jack and could hear background static-y noise but no true sound. I tried playing a DVD to see if I could for some reason get sound like that, but when I put it on the channel for the DVD player, all I get is a black screen instead of the menu screen coming up. Any advice or suggestions you can give to help locate and fix this problem will be greatly appreciated. Thanks.
Since the you were vacuuming behind the set before this happened, I'm going to assume that you unplugged an input. Check the wiring, not just on the back of the set, but, on the back of the peripherals (DVD, Satelite, cable box, etc.) If wires are connected, then, take a component, such as a VCR or cable box and hook it up to the RF connector (AKA the cable connector) and run it on channel 3 or 4. If you have sound, then, you have a configuration problem and need to rewire your set. Hope this helps.
