I need the code for my RAV300 - Yamaha RAV-300 Remote Control

Why ask the same question 4 times, once would be significant. Contact the manufacture or if you're using a universal remote find the codes online.

On the left pane, select Settings. Select Configuring the TV. Select [TV]. to pull up the settings menu on the right pane of the TV screen.

You could try to repair it yourself if you have a basic knowledge on electronics.
Have a look at my instructable: http://www.instructables.com/id/Repair-your-remote-controls/.
Re-soldering the infrared LED and battery connections could help. let me know if this is helpful.

Here's how I got mine to work. FIRST THING: Once it's programmed, you use the TV function keys at the bottom of the remote for Power On, channel changing, etc. The other keys on the remote don't operate the TV.

1) Press the "code set" button with a pen or straightened paper clip
2) Press the [A] key (next to "V-AUX")
3) Enter the code

Test it by pressing the Power key in the TV section on the remote (NOT the "Source" Power" key or Main power key at the top).
