Need To Upgrade TV

Hmmm... That's different. I looked before without luck, but a "monitor" rather than a TV might be more what you need. Used to be once upon a time they were cheaper than tvs - it's just a display with an input.

I have no experience with tuners. Are they external now a days?
No, tuners are internal. The biggest failures I've experienced on the last few we've had have been with the electrical panels where all of the plugs and jacks are. They always seem to get loose and make bad connections. Even the one I have now does it, but I have it in a position where it works and I leave it alone. lol
