I purchased a KDS AV-195TF in Oct and within 3 weeks it was making a continous buzzing sound with an odd looking resolution. I tried changing the resolution rate and updating the drivers but nothing helped. Called the tech support and they sent a new on out in two days. Great service, but with in a month, the replacement was doing the exact same thing. I'm now on my third one and waiting to see if it starts making the same noise. Oh ya, once it starts making the noise, I can't connect to my dail-up service provider. Has anyone else experienced these problems? Any suggestions?
