My RCA F27650 (Entertainment Series) is experiencing all sorts of weird menu problems. It will, at random intervals, popup the system menu or Guide Plus Gold onto the screen effectively blocking the view of whatever I'm watching. Clearing the menu only causes it to pop right back up (this is extremely frustrating). The TV will also randomly enable mute when I'm fighting with the menus. It also randomly decides to no longer turn on/off with the TV power button. When that happens, it can only be turned off/on with the remote. Other than the crazy menus, the TV picture and sound are perfect. Is anyone else having this problem? Does anyone have a solution?
