I disassembled and cleaned the item because it was heavily soiled. It was secured with 5 screws and not a snap-in type. I removed dust from the circuit board with an air duster and wiped it lightly with a paper towel. I washed the plastic and rubber parts with water to remove the dirt. After spraying with alcohol and drying, I reassembled the item and tested the infrared response of each button. The power button on the top left and the TV control power button on the second row from the bottom only responded properly when pressed with a little force and held down (for about a second). The main power button is practically fine, but the TV control power button seems to require conscious effort to press. Please check the photos to confirm the condition and understand before purchasing. I will also check the operation before shipping, but please check the operation upon arrival. If there are any problems, please contact me via message before leaving a review. I plan to accept returns if you return the item via Nekopos or Yu-packet (sender pays for shipping). Please note that I cannot accept returns after a review has been left. I am open to price negotiations, but I will consider the comments and may not be able to respond. I plan to ship via Nekopos or Yu-packet.
