Unfortunately, I can't provide specific code for your Sony TV remote without knowing the exact model number. However, you can usually find the code in the user manual of your Sony TV or by contacting Sony customer support. Alternatively, you can try using the auto-search feature on your newstar ntr b28z remote to find the correct code for your Sony TV.

To find the code for your Sony TV using the Newstar NTR B28Z remote, you can try these general steps:
Turn on your Sony TV.
Press and hold the "TV" button on your Newstar remote until it blinks twice.
Enter the code for Sony TVs. Some common Sony TV codes are: 0000, 0011, 0080, 0111, 1234. If none of these work, you can proceed to the next step.
Press the "Power" button on the Newstar remote. If the TV turns off, the code is correct. If not, try a different code.
Once you've found the correct code, press the "TV" button again to lock it in.
If none of the provided codes work, you might need to consult the manual of your Newstar remote or contact their customer support for assistance.
