Without the remote, you may not be able to change the input mode. Two things you can try:
- With the TV on and in TV mode, insert a disc into the DVD slot and see if the TV automatically switches modes
- With a DVD inserted, press the Play button on the side of the TV and see if the TV switches modes
For the location of the Play button, see page 11 of the user manual.
- With the TV on and in TV mode, insert a disc into the DVD slot and see if the TV automatically switches modes
- With a DVD inserted, press the Play button on the side of the TV and see if the TV switches modes
For the location of the Play button, see page 11 of the user manual.
