Arris XG1v* - Blew TV Main Circuit board via HDMI connection?
I had an interesting event happen recently. I am mostly looking to see if anyone else had a blown TV that fits my symptoms. Not suggesting at all that ARRIS XG1V* has issues.
We had a recent power outage due to some electrical issues OUTSIDE of our place. Our neighborhood lost power for about 4 hours. Our Utility company (VA DOM) did some outside work on poles and underground to fix it.
After this was fixed, I had two things happen inside. First was that my Cox ARRIS XG1V* lost its front panel display. I powered it on multiple times, but all lights on front stayed off. It was completely non-functional because my 2nd slave Cable box that runs off of the primary box, but now now blown, couldn't talk to the primary box anymore. I got a replacement for it from local cox store
The more interesting part is that my TV stopped working too. I can turn it on, I can see he screen light up, but nothing beyond it. I can't change input, or watch Blue-ray or chormecast, built-in Netflix/Youtube or anything at all on any of the inputs.
I had a TV guy come over and diagnose that the Main TV Video board (LG 60PB6900) is blown. It is going to cost me about $365 to get it rebuild. New ones are on back order, and likely discontinued.
During our conversation, he happened to mention that we should be careful about connecting LIVE HDMI cables because they carry 5V current and that 5V pin could accidentally contact neighboring pins frying things. Now this was an interesting point that lead me to write this post. If the power surge was as bad as it was, my TVs power supply likely would have blown too. So I suspect the event that caused the main circuit board to get blown came from somewhere else. The ARRIS box getting blown might not be a co-incident if I apply non-scientific relative logic.
So my question to all of you is that have you heard any other issues with ARRIS box similar to this? Also, what are the possibilities of ARRIS blowing up my TV main board via HDMI?
And the most important question of all this is that what are chances COX would buy this as a defective equipment and reimburse me to get my TV Fixed? All I have is a co-incidental event and a fairly confident TV fix guy.
I am going to be definitely putting in an HDMI surge protector. But there doesn't seem to be a whole lot of awareness around HDMI surges. I love my 60inch plasma and I would like to hang on to it as long as possible!
