Advertisements Hi, I just bought my first TiVo on eBay (a used TCD540040). It always makes a high-pitched buzzing noise regardless of whether it's recording or not. It's so loud that it keeps me up when I try to sleep and can hear it over the volume of the TV when the TV is on. It doesn't sound like any electronics components I've ever heard before (different from any hard drives or cooling fans I've heard before). Is this common with TiVos or is there something wrong with the one I bought?
