Remember these Smart TVs are like this. There are so many priors that I won't write at length on new Smart TV complaints but share common ideas or possible fixes.
I have a LG 32LM6410 3D Smart TV.
For the past few days, V Tuner is not working. I get the following message now :
HTTP Error 404. The requested resource is not found"
Kindly guide me on how to get V Tuner working.
