Re: e701i-a3 no picture but backlights

Everything is back together after testing power up after every step of reassembly. I did a factory setting reset for color and sound so I could tweak it from there. I was able to connect to my wireless router and watch an episode of Planet Earth on Netflix. Wow what a big TV. Too bad I lost one side but at least it's alive and I'll find something to do with it. It was fun. Thanks again.

Re: e701i-a3 no picture but backlights

Add me to the club. It was a great experience. My left side tab drivers were bad. The short wire extension trick saved me time and trouble plus kept the board from getting abused. I now have a beautiful picture sound and an extra tcon board plus five or 6 spare transistors. Total cost 80 bucks. Feels good to save it from the dump for a few months, year or years. who knows.
Thank you all. Great blog.

Re: e701i-a3 no picture but backlights

Just wondering if I could solder a few inches of some small gauge wire to the pads where the transistor sits on the board and have an extension cord of sorts in order to make replacing the next blown transistor easier. If that would work, I would just leave it hooked up that way and lay it down insulated from other components for the next time if needed.

Well, that was a fast 3 seconds. I got my tcon today and installed . I plugged in the two cables coming from the main board and had the LCD cables unplugged. All voltages seemed to be close or correct. The tcon looked good. I took a break to cook chicken on the grill and decided to give it the 3 second test with the right side LCD drivers unplugged. Yes the small 3/4 inch ribbon on the side board right side bottom corner by the vizio logo. I was going to unplug the left side as well but thought it was a 50/50 chance that the right was the issue....

Re: e701i-a3 no picture but backlights

Wish me luck. I'm going to try and save a dumpster bound e701i-a3e. T-con is being shipped. Thanks to all who have posted with info and procedures. I'm well read twice and looking forward to seeing what happens. I'm up to page 16 and until I get the new board, I'll read and reread pages 17-45. Then I'll read again. thanks. I'll post end result one way or another.
