This Sony stereo receiver is in partial working condition. The input/outputs, volume, buttons, all seem to work fine after testing. The problem lies in the screen. Although the stereo seems to function just fine, I cannot see anything on the screen. I’ve heard that the issue could be a dimming setting that needs to be turn up, but I do not want to mess with it. I hooked up a multiple devices to the receiver, like a tape player and CD player, and connected them to all the audio inputs, and all of them worked fine, just can’t see anything on the screen. If you have any questions, please feel free to ask!
