Hello Chris, did you test if the remote cotroles emit?
to test take the cell phone, put it in camera mode and point the transmitter of the remote control at the camera and press the buttons, every time you press you should see a light on the transmitter of the remote control, if you do not see it, the remote control, it does not work
There would be another test to perform, only if you have an Onkio Receiver, with control output on the back panel, if you have it, you have to place a 3.5 mm Miniplug cable to the 3.5 mm Miniplug, from the DVD player to the the Receiver, this can be seen on page 19 of the user manual of your Onkyo DV-CP702 DVD, with this connection you use the remote control of the Receiver to control the DVD
I hope you can solve the problem
Greetings Franco Dosil
Hola Chris, probo si los cotroles remotos emiten?
para probar tome el celular, pongalo en modo camara y apunte el emisor del control remoto a la camara y presione los botones, cada vez que presione tendria que ver una luz en el emisor del control remoto, si no la ve, el control remoto, no funciona
Habria otra prueba para realizar, solamente si usted tiene un Receiver Onkio, con salida de control en el panel posterior, si lo tiene, tiene que colocar un cable Miniplug 3,5 mm a Miniplug 3,5 mm, desde el reproductor de DVD hasta el Receiver, esto lo puede ver en la pagina 19 del manual de usuario de su Onkyo DV-CP702 DVD, con esta conexion usa el control remoto del Receiver para controlar el DVD
Espero que pueda solucionar el problema
Saludos Franco Dosil
