Why don't we use the service menu to calibrate TVs?Why we stopped tweaking the service menuA couple of years ago, I decided to stop using the service menu for calibration of TVs I review. I did so for what I consider a few very good reasons.First, most CNET readers (and 99.9 percent of humanity as a whole) would be confused by service menu settings, and asking them to access a "secret" menu that has the potential to really mess up their TVs is asking for trouble. That trouble could come from both confused users and irate manufacturers which, understandably, want to restrict service menu access--if only to reduce the inevitable flood of calls to customer service. Second, accessing the service menu is something the vast majority of owners would never do, or even think to do. A review of a TV performed without service menu adjustments, more correctly reflects how that vast majority of viewers will actually experience the TV in everyday use, after a reasonable number of adjustments to user-accessible controls. In addition, concentrating on the user menu gives TV makers credit for instituting better settings, and encourages them to make improvements. LG is a very good example. I've lauded the company for including numerous picture settings, and indeed, its 2009 Expert user menu, seen on the LH30 series for example, is better than what's available on any service menu I've seen. Samsung, Sony, and recently Sharp and even Panasonic offer white balance gain and often cut/offset controls for grayscale adjustment. TV makers pay attention to CNET reviews, too, and I have been told by more than one engineer that what I write figures into their designs. Finally, ignoring the service menu saves me time. I'm basically the only one who reviews TVs for CNET. Adding a service menu calibration would increase the amount of time spent for a review quite a bit, not least because I'd feel obligated to review the TV in both user menu and service menu calibrations to accommodate users who don't want to risk accessing that menu. In a perfect world I'd have enough time to do this as well as institute other, more in-depth evaluations that I'm sure would please enthusiasts. But I just don't have the time.
