The TV is over a decade old (LG 42LM669T-ZC), so it could be that it's just done, but if anyone has any ideas of things that might be easy to repair I'd be grateful.
About a week ago I noticed that when watching TV a hissing sound would start. At first I thought this was an issue with the firestick I was using as I found that changing sound options in this could temporarily stop the hissing, though it seemed it was the changing the setting interrupted the problem rather than that one setting caused/solved the problem.
After a while of tinkering with every audio option possible that problem seems to have disappeared, but been replaced with the TV now doing an occasional pop sound, then a brief (less than a second) silence.
It's possible this doesn't happen right ways, but starts after watching for 15-20 minutes.
This only happens with audio from the TV to my amp and all other inputs are fine. It's a problem both via the HDMI and optical connections. I've checked all the cables are secure and clean. I tried to gently hoover the TV's vents in case there was a dust build up. I've again tinkered with every audio option I can think of. Nothing seems to have helped.
Any ideas?
It's possible that this doesn't happen when the audio is played through the TV's speakers, but I'm not certain and those speakers are so bad it's even worse using them than putting up with the pops.
