I have a fairly old smart LG TV. 

It's not UHD or 4K. 

Some of the channels have started to flicker, but not all. I use True. 

What could be the problem? 

Could it be that I need a new HDMI cable? I looked in BIG C & they only have 4K HDMI cables. Would a 4K HDMI cable still be okay for me to try? Failing that, I guess a visit from a True technician to check the signal/router etc. 

Anyone had the same problem? Thanks. 

 

For standard definition TV a 4K HDMI cable is overkill, but it will definitely work.  You probably don't need a new HDMI cable.

 

If the same group channels are the only ones giving you trouble, it is most likely due to your TV box getting a poor quality input signal from True.  Your first step should be to call True for service.

This would tend to rule out a defective TV screen and / or other hardware.

HDMI cables are backward compatible. 

 

Have you moved any other hardware around the TV or box?  If so, the box and / or cable could be getting some interference.    

 

I agree with the other member.  If no interference, it appears to be a problem with True. 

Yeah, thanks for the reply. I believe it's a poor signal too. I'll be visiting True soon.

Trying to report a problem online is a waste of time. 

Update. True technician visited checked the signal and changed the tv box. Now everything is fine. He said buffering on some channels is a common problem and the tv boxes on average last between 3 - 5 years.
