I recently bought a Philips 26" LCD TV (26PF5321D/37). When I'm watching video in 720p, there is a bit of overscan. I don't know if there is for SD programming or for 1080i. I understand that this can only be adjusted in the service menu, but the problem is that I don't know how to access the service menu or the particular option that allows me to modify the overscan. I know that a 3-5% range is optimal, so I'm not going to try to get it to 0% or something. So my question is, how can I access the service menu, and how can I adjust the overscan? Thank you.
