I think I know where is it, but I am not sure. How can I recognize it?

ThermalRunaway said:I've never seen a video recorder which uses optical methods in place of a mode-switch. Every model I've ever worked on, including the latest ones, still use a standard rotary encoder. Even camcorders that I've worked on use them!
You must be working on a model of recorder that I don't and vice-versa. I think I remember you saying that you service a lot of Sony products? I don't service any of those, so possibly that's why we're having a difference of perspective here.
Video recorder servicing is becoming increasingly rare altogether these days though. I can go weeks without looking at even one unit now, the things are so damned cheap that nobody wants them repaired anymore.
