I have confirmed that it is working. It has been stored at home. It has been used infrequently. I bought it for my daughter, but she hardly used it. The DVP-FX780 is a model that emphasizes "ease of use" and "enjoyment of sound" while firmly maintaining basic playback performance. With a compact 7-inch LCD screen, it can play DVDs, CDs, MP3/JPEG discs, and can continuously play for about 4 hours on the built-in battery. It also has multiple sound modes (sound quality adjustment function) that can change the way sound is heard, allowing you to enjoy movies and music with more immersive sound. Furthermore, it has an A-B repeat playback function, which is convenient for language learning. Accessories include an AC adapter and a car battery adapter. 7-inch portable DVD player with DVD playback function.
