I've never loved the Jensen TVs. Amazon's 32" was on sale for less than $100 (I'm sure it will be again). So I figured I switch out the front TV. I also may swap the back TV for a 24" PC monitor connected to Firestick, but the difficulty getting to the screws in the back has slowed me down.
I thought changing the front one would be easy, but I probably made it harder than it needed to be. I'm pretty sure (now) that you can remove it by pushing the black tabs on the sliders through the back. ... After removing the bathroom mirror, some holes behind the TV are most likely meant for that purpose. However, once it was all off, I decided I didn't need the slider and just bolted the TV directly to the wood.
I think it looks nice, and having a 32" diag is better than 24". It's still only 720p and since it only has HDMI inputs, I didn't hook up the DVD player. It would be pretty easy to use a video-to-HDMI adapter (Amazon has them for $7). So I may add it later.
