Due to aging or specifications, the LCD is dim, so the LCD setting has been adjusted to be darker. The LCD setting can be adjusted within the range of [1-16], but at the initial value of [5], it is almost invisible from the front in a bright room. The visibility changes depending on the room's brightness and angle, and it is clearly visible when viewed from the playing position (diagonal) in a dark place like a stage. (目安 - Guidelines for clear LCD settings) Bright place + front: [16] Dark place + front: [12] Bright place + diagonal: [8] Dark place + diagonal: [5] Since the HPD-15 I previously owned had the same issue, it is likely a specification considering performance, or a specific type of deterioration. Note that the LCD is different from the electronic drum module TD-20, so there is no display distortion or dimming during use, and there are no problems with use. Also, the main unit will be initialized (factory reset) at the time of listing and the LCD value will be set to [16]. The operation is good, and the response of the pads is normal in all sections, and the buttons, input/output terminals, and various setting screen operations are all normal. There are scratches and dents on the back and sides. There is no major damage such as breakage or cracks. The instruction manual is missing, so please refer to the web version.
