TV has no Wi-Fi

Do you experience any TV no Wi-Fi issues?

Problem Reasons and Indications

If your Smart TV won’t connect to the Internet via a router, there are several possible roots of the issue.

Wireless module malfunction

There are 2 basic «symptoms» of this problem:

1) TV Internet connection drops or intermittently disconnects whereas all the other devices can connect to this network without any problems.

2) It’s impossible to connect to the Internet as the network settings are disabled. The Wi-Fi switch is in the off position and inactive. The attempt to reset TV brings no result.

Mainboard firmware errors

Such issues occur due to the malfunctions of the mainboard Wi-Fi module software.

The problem is particularly apparent when the wireless connection is not happening or it may be hard to manage the Internet settings.

Mainboard or T-CON short circuit

Both motherboard and T-CON are the most vulnerable components of any 4K TV. Microcracks may easily appear on these parts because of a power surge. In such cases the TV turns off spontaneously after a while, the power button flashes constantly, the indicator lights up and immediately goes out. And of course, the TV has no Wi-Fi connection.
