Default VIZIO 70" LED TV issue

Hi there, I'm new here and I was looking for a TV forum and found this site so I'm here!

Anyway I purchased a Vizio 70" Led TV on January 19, 2014 in time for Super Bowl at the time. Go Broncos!!! Lol anyway the model is E701I-A3E.

Over 1 1/2 months ago after Thanksgiving, the TV went out but could see the black screen on background. Thankfully I purchased a warranty from the store so somebody came on Dec 7th to repaired it. It was the T-conn that was replaced and it works fine.

3 weeks later, the TV went out with my own eyes with exactly issue. So I'm thinking it's something more than the T-conn? Can anyone helps out?

I did file a claim again, they were suppose to come out but I end up getting refund for the TV. So now I want to repair the TV myself which I did record the repair guy who fixed the TV a month ago so I know what to do now.

But the question: Is it something just more than the T-conn itself or else?

The TV is able to turn on itself but it will just show black screen, it doesn't show the TV Vizio logo like usually so I know it's the T-conn board handles video or something like that but more to it? Any experiences?

Thanks!!!!!

Some Vizio's have a cap problem on the power supply board, look for some small metal can's, these are electrolytic caps, they can dry out, and they will go bad, if the tops of these cans are not flat but bulged up then they are bad, replace them with the same voltage and MFd rating.

But be careful when you do this so you don't damage the PCB by lifting up any circuit traces.

After researching more through google and came across one of youtube comment:

( "I have a Vizio E701i-a3 with no picture. The backlight and sound are still working. From this I decided to gamble and try replacing the T-Con board. I purchased one through ShopJimmy and received it today. I replaced the T-Con board and reinstalled the back. I turned on the TV and was excited to see that it was working! Unfortunately this only lasted for a minute or two before the picture faded out and would not return. Do you have any idea what would be frying the T-Con boards?

ShopJimmy 4 months ago replies

Try all repairs and troubleshooting at your own risk. This sounds like a TV panel (TV Screen) problem. If your TV panel is bad, it may be more cost-effective to replace the TV as panels are typically hard to find in stock, difficult to replace, and expensive. Thanks and please let us know if you have any further questions!)

Now I'm curious what other around here will answer to that? thanks!

Got another T-Conn part today, replaced it and the TV still showing black screen, nothing came on except the backlight so my best guess it's the panel?
