I saw, in your last post, the instruction manual for your JVC TV, and was impressed. This looks like a very well-built TV, which should work well if not abused. The warning regarding image burn-in could apply to any LCD TV (which is why most if not all LCD televisions have screen savers), so I wasn't surprised when I saw it in the manual. I'm thinking today's LED-LCD flat screen televisions, like my 32-inch Insignia, to mention but one, are not nearly as vulnerable to screen burn-in as the JVC, which is a much older set (by a few years). However, your JVC TV seems to be built like a tank, so when you get it working as it should you should have a TV which will last years, as long as the usual precautions are followed (don't leave a stationary image on the screen, such as a color-bar test chart or test pattern, any extended length of time, for one).

You mention in your post that your JVC TV is built very solidly, which is very good news if you want your TV to last a long time. LCD TVs (LED-LCDs too) are extremely fragile, so it is very important not to set the TV on its screen for any reason and, of course, be absolutely certain the set is mounted solidly to any stand it is put on.

Any flat-screen television will suffer permanent damage if the screen is struck or shattered by any means or in any way, unlike the old CRT TVs which could take almost any kind of abuse and still work normally unless, of course, the CRT neck is broken or the screen is burned by negative ions. The latter was common in the early days of cathode ray TV picture tubes, and ruined many such tubes by producing a burn mark on the screen, which was round in the case of rectangular CRTs and X-shaped on round tubes (or vice versa; I'm not sure). These tubes used a device known as an ion trap to prevent such screen damage; however, the device had to be set exactly right so as to offer the maximum protection to the screen.
