This is a rarely used, slim-design TV. It's in very good condition overall, with no major scratches. I've checked its functionality thoroughly. All terminals work well with devices like DVDs, digital cameras, and game consoles. I've tested it with my DVD player, digital camera, Amazon Fire Stick, Switch, PS4, and PS5. Dual display with a PC also works perfectly. The audio is clear with no distortion or crackling (even at maximum volume). I've connected headphones and a 5.1ch external speaker system, and both worked flawlessly. The built-in DVD player sometimes plays DVDs and sometimes rejects them, depending on the disc. Therefore, I'm selling the built-in player function as junk. Please don't complain if DVDs don't play. Regarding the remote control, only the power button (the red button in the upper right corner) has poor sensitivity. All other functions, such as menu settings and input switching, work perfectly. If you're concerned, you could purchase a universal remote for around 300 yen. Antenna reception is also excellent. The card is included. Regarding wall mounting, the screw positions are within the standard, so it's compatible with general TV wall mounting brackets. It's lightweight, so you could easily mount it on a wall. At this weight, staples in plasterboard should be sufficient. My own bathroom TV has been held up with staples for about 8 years. It even survived a magnitude 5.5 earthquake without issue. By the way, it's a 24-inch model. Please do not bid if you are expecting a brand-new, pristine TV like those in the electronics store, or if you are overly sensitive to even a single rusty screw. Please ask any questions you may have in the question section. No returns or refunds.
