I recently had the HDMI port and Main Board on my Samsung Plasma blow up when I connected a refurbished DVR to my TV that Directv sent me.
I am hoping someone can shed some light on this for me, I will try and type a short version of what occurred.
First things first, the electrical wiring in the house was recently upgraded, within that last 2-3 years I believe. I have a Samsung 50" Plasma that I've never experienced any issues with (I understand over time normal wear and tear can occur, I'm just pointing out that there have never been issues prior to this).
I had the Directv cabling and equipment upgraded less than a year ago.
I have had a surge protector connected to the wall outlet since I moved back home, with my TV and some other electronics connected to it including an HP all in one desktop.
About a month and a half ago the HD DVR I had upgraded less than 8 months prior, suddenly had a hard drive crash. Nothing else was affected just the DVR.
I contacted directv and had to pay $22 shipping for a "replacement DVR" which turns out, all their equipment is refurbished and they don't send out "New" equipment. Anyhow, when the replacement DVR arrived I went about setting it up per usual.
About 5 days later out of nowhere, the circuit breaker is tripped in the house. I unplugged everything, went down to the box reset the breaker, etc...etc..
I went to plug my TV and DVR in and BOOM, breaker tripped again. Followed same routine as above but this time I disconnected the TV from the DVR entirely and plugged my TV into the outlet, it powered on normally, no issues whatsoever. So I powered it down, unplugged it and reattached the DVR. When I went to plug the DVR in all of a sudden, circuit breaker tripped again but this time I saw a poof of smoke, the wires from the DVR to my TV were melted and when I unplugged everything in a panic and reset the breaker I decided to let my TV sit for a few hours before checking to see if my gut feeling would be wrong but sure enough, several hours later after making sure the DVR was disconnected from the TV entirely again, I plugged my TV in and it was fried
Keep in mind, the only time the circuit breaker tripped was when the DVR was plugged in!
I contacted Samsung to have a tech come out and check out the damage and also had to tweet on Directv's twitter page to get someone to contact me because miraculously I always get disconnected when on hold for 30+ minutes when calling Directv.
Samsung tech came the other day, opened up the back of the TV and the Main board on my plasma was fried, there was black burns right where the HDMI ports are and it was determined that the Main Board would need to be replaced but there was no guarantee that there wouldn't be more damage uncovered once the main board was replaced.
I submitted everything to the Directv claims department and of course within a day they send this kid here to "check the damage" no problem, I expected that.
When he arrived this afternoon I opened the door and let him in, but asked "where are your tools? Didn't you say you needed to see the damage?" I did send them the pictures the Samsung tech took when he was here with the claim information but it didn't make a whole lot of sense that the guy would show up with just his smartphone to evaluate $1000 in damage.
After snapping picture of the back of the TV which clearly shows diddly squat unless the back cover is removed, he asked to see the outlet. No problem. Plugs in his little $1 Home Depot outlet checking thing and says "your outlet is no good". Basically, screw you, Direct is going to weasel their way out of this one way or another....
I calmly said, okay, but the DVR is what kept causing the circuit to trip and explained the process of elimination I did before I made the fatal mistake of reconnecting the DVR to my fully functioning, non problematic TV that powered up just fine with the stupid DVR. As expected, "Well, I don't know what to tell you but your outlet is no good". Trying to keep myself composed while knowing this would inevitably leave me holding the $1000 bag.
Why they sent some ding bat here without anything but a smartphone pissed me off enough as I had to pay for a real tech to actual open the back of the TV to see the damage clearly was caused from the connection to the DVR where the HDMI port is. Moving on....
Here's what I am curious about, and I'm not being rude but please understand I'm a bit frustrated right now and don't want someone to tell me to take an electricians 101 course. I've been working on computers and electronics for over a dozen years but have a very specific question for someone who is knowledgable about electrical wiring.
With all the details I've provided above, and the fact that nothing else was damaged or triggered the circuit breaker but the DVR, the damage to the TV clearly shows that there was some sort of surge that ran through the HDMI cable connected both the DVR and to the TV's main board which is fried. CAN the DVR have been the cause of the damage to my TV and furthermore could the fault in the DVR have cause whatever issues to the outlet/wiring the kid with his camera phone said was "no good"?
I greatly appreciate any advice as I'm 35 seconds away from blowing my lid!
