Thank you for viewing. This is a SONY CD player. It's a CDP970. Whether the lens is dirty or the laser strength needs adjustment, it can't read CDs when you press the switch normally. It will play if you clean the lens with a cotton swab. Years ago, I adjusted the laser output and it worked normally, and I was able to use it for a long time. Recently, cleaning the lens with a cotton swab allows it to work only on that day. Sometimes, it plays normally without doing anything. Because it's a component stereo, the sound is good and has depth, and I listen to it like this even though it's a hassle. Once it reads a CD, it plays properly, so it's a very good mechanism. This time, I'm going to get rid of all my components and I'm putting it up for sale. It weighs about 5 kilograms. The size is 430 x 110 x 340. It comes with a remote control. Those who can adjust the lens area, please consider. Since September, it's been playing normally for some reason. It might be temporary. Since it's old, it's being sold as junk, please understand. For enthusiasts, those who can repair it, and collectors, please consider.
