I have a new TV that is about 3-4 months old. It is a Sony 31?? inch flat panel with the picture tube. I bought it at Best Buy. Anyway---It makes this Star Wars "light Saber" sword sound when I first turn it on. And once the picture appears, all is fine. Is this the Picture tube "warming up?" Is there cause for alarm? DO I need to take it in? Picture is fine, changing channels is fine, I just don't want to overlook this and then start having problems with it after the warranty has expired.
Nope i have heard this sound as well in new sonys. I have recently been in contact with a few new sets and they do sound weird my freind. It sounds like a WWWEERRRRZZZEERREERRZZUUUP! LOL Its the deguassing curcuit doing its job. And yes it does take a short time for the picture to come on as the horizontal circuit does not stay on in newer sets so it will take a short time longer then whats called instant turnon, before the screen will come on.
