Query: Doesn't cover all TVs

Be careful before you buy this that it has a code for your TV. It has no code for Norcent TVs, nor can it "find" one. All my other universal remotes either came with a code or found one with their search function. Also the code search function on this remote is tedious and gives no feedback, so I spent a half hour pushing channel up-power off with no results and never any feedback.I bought this remote because the mute button died on my old remote. The remote did successfully learn to mute and adjust volume up and down. But it's soooo not worth it to have a third remote just to be able to mute my TV! I tried programming it to work on my other TV of a different brand, but also an older model, and sure enough, despite having a code for that brand, it wouldn't recognize that TV either! My $5 Magnavox universal remote found it immediately.This is my first Sony electronic item and my last for sure. Definitely NOT worth the money or effort.
