Found during a home clean-up. These items are several years old and have been stored at home for a long time. acer: No cable, so I haven't been able to check if it works. SHARP: The lamp turns on, but the screen remains completely black. One button is missing. Also, I have no knowledge about these items, so I don't know anything else. I would appreciate it if you could understand that these are junk items. There is dirt and cracks on the main bodies. Please check the photos.
