Can a HDMI Cable or Blu-ray disc's audio blow out speakers?

[TheHighRoller]

Hello guys,

This may seem like a stupid question to some of you, but I was wondering if a Blu-ray disc's audio encoding could possibly contribute to a blow out or mess up a TV's speakers/main board? Or would it be all on a faulty HDMI cable?


When I got my Vizio 55" TV two years ago from Costco, we forgot that HDMI cables were sold seperately. So we went to a store and bought a generic no-name HDMI cable for like $7.99. This thing honestly has no make and model number, let alone a brand (it does have numbers, but they don't look like a model number). I know they say all HDMI cables are the same, but I honestly don't believe that.

Since getting that HDMI cable, whenever we watch a Blu-ray, watch YouTube, or use the PS3 for gameplay (the main Blu-ray player is the PS3), sometimes the image and/or sound will go out for like two seconds, then go back on. Only a few times out of that, the sound will make a faint pop. In total, we may get this go on/go off problem maybe once a week or once every two weeks (but when we do get it, it happens like 3 or 4 times until we change the HDMI cable into another slot- then it starts again a week later). We also sometimes turn off the TV for about 20 seconds and turn it on and sometimes that seems to help.


So in May, I watched a brand new Blu-ray disc that had LPCM 1.0 Mono Audio (48kHz, 24-Bit), and as soon as the disc ended, the speakers blew out. Throughout the film, I thought it was strange how some parts were softer than others (It's a Criterion, so maybe this is attributable to the original audio source). I have since replaced the main board (back in May), and I recently decided to re-watch the Blu-ray again a few days ago, and I noticed that the image would turn off, then back on as it did last time (I heard a faint pop when it did). On the good side though, nothing happened to the audio. So I honestly think this is HDMI cable related.


I'm now planning on buying a better HDMI cable, either Sony or Monster and hope that it really is the HDMI cable after all.


But still, is it possible that the HDMI cable or the Blu-ray disc's audio encoding could have resulted in a messed up main board? I would blame it on the TV, but like I said, the main board was replaced (it was purchased directly through Vizio and installed by a professional), so I don't think the TV is to blame.
