My grandma is having trouble with her TV again, could you write basic step-by-step instructions on how to switch the input to the DVD player and play a DVD?  you can generalize, i'll add in specifics if i need to.  add my number at the bottom if she has trouble 555-7878
1. Turn on the TV and DVD player by pressing the power button on each remote control.  You'll know they're on when the TV screen is on and the DVD player has a red light visible.

2. Open the DVD player disc tray by pressing the eject button on the DVD player itself, or its remote control.

3. Put the DVD you want to watch in the disc tray and press the same eject button as before to close the tray.  If you close it without pressing the button, you may damage the disc.

4. Locate the "INPUT" button on the TV remote control and press it once to bring up a list of inputs.  Press "INPUT" again until the input named "HDMI 1" is selected.  This should bring up the DVD menu on the TV screen.  If this isn't the case, check to make sure the cord running from the TV to the DVD player is plugged.

5.  You now have control of the DVD with the DVD player remote.  You can navigate the menu with the arrow keys, or just press play to start the DVD.  The rewind and fast-forward should work.

Please call me at 555-7878 if you have any questions!
