Sony RL-1026 Flexible Board (A1992172A) is a service replacement board for the camera’s control functions. Sony’s service documentation identifies it as the complete RL-1026 board, with the matching service part reference A-1992-172-A.
The board diagram marks ON/OFF, shutter and zoom controls, making this the relevant assembly for servicing those controls. The parts list also identifies mounted detection and tactile switches, alongside a resistor and resistor network. These details help distinguish the control board from other flexible boards in the camera service documentation.
This is a camera service component intended for repair work, rather than a general-purpose flexible board. The manual documents RL-1026 in connection with the Sony DSC-RX10.
