Adjusting sound settings
Not everyone knows, but an effective way to troubleshoot problems is to adjust the TV settings to turn off its speakers. This debugging helps stabilize the soundbar. If it is not there, and the speakers of the household appliance are not activated, then it will be silent. To check the functionality of the device, you should:

Reset device settings to factory settings
If the TCL technique still works without sound, then you need to return to the factory settings. It is worth remembering that these actions will return it to its original data and a number of applications will have to be installed again.

TCL’s tech support staff knows how to deal with this sort of thing and has most likely seen complaints about the lack of audio before. Consultants know how to take the required corrective action and make sure the user is able to handle it on their own. If their advice does not help, they will send a master.
It is very important to clarify whether the warranty period for this TCL TV is still valid. For most of the company’s equipment, limited commitments are issued, covering only the first year of operation of household appliances.
The contract covers defects in materials or workmanship from the original owner of the TV device, provided that it was purchased new from an authorized dealer. If the company decides that everything is as written, then they will pay for the repairs or provide the owner with a new technique.
In most cases, problems arise with TVs that have worked for more than 12 months, but, nevertheless, it is worth clarifying the availability of a guarantee.
