Question about Televison & Video

2 Answers

What is the reason for my E701i-A3 failure? All boards were replaced, worked for a minute, and then had the same "fade to black" failure as the first time.

First failure: Screen went mostly black except for a small area that gradually reduced in size until the whole screen was black. I replaced all the main board, power board, and t-con board (simultaneously). When I started the tv back up again, it seemed to be working (full screen image, bright, etc). But after about a minute of me navigating around the screen again went mostly black except for an area towards the bottom right that slowly went to black (from outer edges to the center). I don't want to give up on this TV and feel like there must be something shorting the boards to cause this failure. Is this TV junk? Is it something that can be fixed? Thank you for your help.

Your back light controller board or the ballasts for them may be bad if they weren't incorporated into the power supply board.

My vizio e701i-a3 turn on but stay in blank black and after 1 minute it turn off whats the problem


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

I have a Vizio E701i-A3 Edge lit LED TV. I looks like an 8 inch strip of the LED edge lights along the bottom are not working. Do I need to replace the light or the T-con?


Tcon is the board that sets the tone for the whole image. If you have a small section that appears to have no backlight then the tcon is not your likely point of failure.

Powers on, backlight comes on then power LED and backlight slowly fade and turns off after about 45 seconds.


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
