One TV (Model: 50l4353d) has a black screen when I turn it on. However, when I flash a light onto it - a image appears. So I think the backlight isn't working but how would I fix this?

The other TV (Model: 32w3453db) works fine for a few seconds after turning it on. However, a few seconds after being turned on the TV stops accepting inputs from the remote and the buttons on the TV. This means that the image works fine but I can't change volume, programs, open the menu or even turn the TV off without unplugging it. How would I fix this?
1. Replace the backlight, but could also be a board issue.

2. Probably a system board issue, again, try replacing it.

Finding parts for the above would mean doing a web search for said parts. Days of the TV repair guy in a corner shop with tubes and screens in his store, like milk delivery in glass jars, are gone LOL Manufactures won't have many spare parts they make, and those they do make will go out to authorized repair sites.

3. It will probably be cheaper and easier to just buy used working TVs.
