Sony video 8 walkman GV-S50 NTSC and Tuner

Description

Up for sale Sony video 8 walkman GV-S50 NTSC and Tuner.
Seems to function and works I just can’t get the sound to work.
Not sure what the issue is.
Needs a new battery, doesn’t hold charge.
Power supply also doesn’t work went it’s plugged into the device. It think that needs to be fixed or replaced
Comes with finer tgv-3
I know this was a very expensive unit when it came out
Please see pictures
