I’ve had cellphones before that NEVER interfered with the sound on my tv. But when a neighbor comes by with their cingular phone it sounds horrible! It sends a high pitch sound to my tv that doesn’t go away even after you turn off the tv until a minute or two later. My upstairs neighbor has a razor too and I notice sometimes that my tv is making that same sound when he uses his phone in a certain part of his apartment.
Now I have one. I like the look but I can’t stand the sound, plus what’s the point of having a cellphone if you can’t have it on when you’re @ home? Other than getting rid of the phone or moving it to another room, is there a way to stop this frequency prob? It goes off ever couple minutes when it’s not in use (no it’s not really close to the tv either)…
Is it the razor phone or the cingular service that’s emitting this horrible sound? It also will happen if my phone is on and I have my noise canceling headphone on, it sends a painful pitch to them as well.
GSM phones are known for causing interference. You can probably eliminate the noise on your TV by making sure your satellite/cable box is properly grounded and connecting everything upstream of it (TV, VCR, TIVO, etc.) using excellent quality shielded RCA cables instead of coax. With your TV on A/V / Video In mode, you won’t get any more interference. As an added benefit, you’ll also get a much better picture.
Now if you’ve just got the cable wire running out of the wall straight into the TV, you can reduce the interference by buying a excellent quality surge protector with a built-in cable noise filter. On the other hand, if you’re unlucky enough to be using a set of rabbit ears, you’re just going to have to place up with the interference – that’s why TVs come with that disclaimer by the FCC. (… this device must accept any interference received, including interference that may cause undesired operation.)
As for the noise on headphones, you’re just going to have to relocate your cell phone away from the headphones, or switch to using passively powered headphones which do not contain ambient noise cancelling circuitry (which is basically an amplifier running 180 degrees out of phase).
It’s a Cingular problem. Not just Cingular either, it’s a gsm problem. There is not much you can do other than switch to Verizon, or Sprint or something like that. Sorry, but hope you figure something out.

We have Dish and my sister has a Cingular cell phone. We used to get that noise real terrible on the phone and the t.v. Now we have some kind of filter (came with the equipment) that we place on the phone line plug in. Maybe there’s some kind of filter you can use.

It’s because Cingular is GSM, which means that it works off of satelites, so it does have a stronger signal. So no it’s not the RAZR, but their service is still better than everyone elses.
