It looks like the wind idler is not moving into engagement. When you select either wind mode, the idler, located centrally between the two reel hubs, should rise up into contact with the rubber tyre on the end of the reel motor pulley. Depending on which way the motor runs, it kicks over to transmit the drive to one or other of the reel hubs. But it doesn't seem to be moving at all. Check it's not jammed with stiff grease, that the spring is attached and that the solenoid is working.

I think the head block is engaging as I think I can see the pressure pad move, so the lack of playback is probably an electronic fault, maybe power or mode selection related as it affect both channels.
