I no longer have digital TV channels. Has Sophon Cable TV discontinued them in South Pattaya and Jomtien?

No problem on the other side of Pattaya.. to the North. 

I still have them, but they seem very unstable lately and every now and again I lose them for a few minutes to a couple of hours, screen just shows a no signal message.   

TMN cable channels are fine. However I am not going to renew when my subscription ends as they like Sophon have stopped showing Astro Supersports 1,2 and 3 ie all the English Premier League games. I have just signed up for Wizz IPTV at £75 for a year 1,000's of channels from across the world.

Yes, they have suddenly stopped to show Astro Supersports.
