You are attacking this back to front. The Universal Remote is irrelevant, it is all about the the television make NOT the remote. Not that anyone uses Universal Remotes any more! And they aren't 'access codes' they are Remote Codes. Have a read

What is the signal source? The TV subtitle control will only work for OTA channels (RF) and possibly native apps. For a Roku TCL TV, go to Settings from the Home Page. This should put you in the Options configuration display. Select Accessibility and press OK. Navigate to Captions Mode and set to OFF. Then click OK to save the setting.
If your source is a set-top box of any sort (cable/satellite box, DVD Player, etc), you have to turn off the subtitles from the box's remote/menu. Depending on the device, this could be easy or hard. One of my neighbors had a single satellite box for two TVs and needed captions on the second set. That meant turning on captions on both sets using the menus on the main TV. On my current set-top box, I have to go to Menu > Settings. Then I enter a code from my provider to access the menu and enter the Hardware settings. On this box, the captions control is under the Audio settings.
I hope this helps. Please add a comment with more information on your source if you need help changing the subtitles on a specific streaming service or set-top box.

These are cheap Chinese made sets that are only sold in South Africa. No one appears to sell parts for them so they are considered disposable. I am in Canada, see if this link works better for you.

Without brand and model, I am hard pressed to help. Even if I had that, some sets have a limited number of buttons on the side that might allow switching input. I would even try disconnecting the HDMI cable or other cabling to a DVD, turning off the set and turning it back on.. But before you do that, look for an input button.
On the side of your TV, look for an INPUT button.
Press the INPUT button to cycle through each HDMI port and available option.
Keep pressing the INPUT button until you find the correct input for your device.
If your remote does not respond to a change of batteries, you may be destined to acquire a universal remote from somewhere like Wal-Mart or Amazon.
Question edited for clarity.
The LED light is a standby light and is on all the time the set is powered on by its On switch.
All sets have Buttons on the set itself, they are either on the lower left or right edge, or the latest craze is to put them on an angled panel on the rear of the set.
If you have a smartphone, you can test the remote. Aim the front of the remote at the front facing selfie camera whilst in photo mode and press the On button on the remote. You should see a red flash on the phone screen.
Try a Power Reset. Remove the television wall plug for 5 minutes and then plug it back in.
