Please read the description and leave a comment. Purchased from the official Yahoo! shop around 2022. Used for about a year, but suddenly started experiencing screen distortion like static and became unviewable. I turned it on for over an hour to check the operation, but the static did not occur. I don't know the cause, but I am selling it as [junk] because it may be viewable but may malfunction. Therefore, please understand that no claims or returns are accepted after purchase.
