My tcl roko remote will not work my head phones will not turn tv sound down an head phone will not work z?

Universal remote codes can vary depending on the brand and model of the remote control you are using. TCL TVs are often compatible with various universal remotes, and you can typically find the codes in the remote's manual or on the manufacturer's website. However, if you don't have access to the manual, you can try the following steps to find the code:
1. **Automatic Code Search:**
- Turn on your TCL TV.
- Point the universal remote at the TV.
- Press and hold the "Code Search" or "Setup" button on the remote until the LED light turns on.
- Press the "TV" (or another applicable) button on the remote.
- The LED light should blink once and then stay solid.
- Press the "Power" button repeatedly until the TV turns off.
- Once the TV turns off, press the "Enter" or "OK" button on the remote to save the code.
2. **Manual Code Entry:**
- Find the code list that came with your universal remote or check the manufacturer's website for a list of codes.
- Turn on your TCL TV.
- Press and hold the "Code Search" or "Setup" button on the remote until the LED light turns on.
- Enter the first code for TCL TVs from the list using the number buttons on the remote.
- If the LED light blinks, check if the TV responds to the remote (try turning it off and on).
- If the TV does not respond, repeat the process with the next code until you find the correct one.
3. **Manufacturer's Support:**
- Visit the website of the universal remote's manufacturer and check if they provide code lists or support for TCL TVs.
- You may find an online tool or database to help you find the correct code for your TCL TV model.
Remember that not all universal remotes are compatible with all TV models, so it may take some trial and error to find the correct code. If none of the codes work, you may need to contact the manufacturer of your universal remote for further assistance.

Press the power switch

On some TCL Roku TV remotes, pressing Volume Up un-mutes the TV. Pressing Volume Down enough times will mute the TV. (A few models have a physical Mute button on the side of the TV.) If the TV speakers have been disabled, you'll need to go through the Settings or Options menu instead. (If the unit was used with a sound system, that would be common.)

For more specific information, please add a comment with the TV model. Usually the remote instructions are in the TV documentation. I can't find any TCL TV documentation that lists the 55R512 remote.

I hope this helps.

To enjoy the streaming capabilities of your TCL Roko TV, it should be connected to the Internet. This can be done via WiFi (available on all TCL Roku TVs) or Ethernet cable (applicable only for TCL Roku 4K TVs). Here's a quick video that you can connect your TCL Roku TV to your home wireless network. You can also mention the step-by-step instructions given below, choose your preferred connection. For more information visit our site: http://www.rokucomlink.info/

You can use the RCA style jacks, Yellow for video White for left and red for right audio OUT . Connect the TV end the same way. Note the source input number on the connectors of the TV. Turn both the TV and the Sony on. On the TV, select the input number the cables are connected to and you will see the Sony . If there are no unused places on the TV to connect to then take off the antenna/ cable wire off the TV and put it on the ANT IN connector of the Sony. Obtain a jumper cable wire long enough to reach the TV from the Sony and select either channel 3 or 4 whichever channel is not used in your area on the back of the Sony. Now turn both on and select TV as the source and put it on channel 3 or 4. Now turn off the Sony and change the channel on the TV to any other one in your area. If there is no picture, then the Sony will have to be on while watching TV.

Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the site linked here. It has set-up code list & set-up procedure to many popular brand remote controls. Pull up older posts.

try pressing the aux button on the front of the reciever while the reciever is linked up to the tv ,if that dont work connect a red and black banana plugs into your aux on the back of the reciever and on the other end of the lead must be a head phone pin check size of headphone socket. to plug in to your tv head phone volune then u can control the recievers volume through the tv using the remote.go to menu then tv set up then scroll to the sound note icon press enter scroll down click on head phone and turn it up then you should have sound through the speakers from the tv.

If you don't have a code you can do these steps to get your universal remote working with pretty much any tv:

1.) Turn your TV on. Then on your remote press the set button, it's the small gray button above the green button that says TV.

2.) Press the TV button. There should be a red light to the right of the SET button. This means that your remote is ready for the TV code.

3.) To find the TV code, press the + or - on your remote. This is located above the orange buttons. Once the volume on your TV goes up or down, stop pressing the + or - button.

4.) Then press the SET button again to set that code for your TV.

If the above steps do not work, keep trying. It will work! ;)
