Re: e701i-a3 no picture but backlights
Update- I have a perfectly working beast of a TV today!!!! Want to give a big shout out to Freakafter8, Budwich, Kevin and everybody else that figured this workaround fix! Let's how long this works for.
After these pictures I peeled the ribbons off the right side panel, pugged in the ribbon cable into the Tcon, turned on and had lots of colorful vertical lines on the right side of screen. I then cleaned the right side ribbon cable and that helped some but still had some light stoving up that Sid of panel. Cleaned ribbon...Leave a comment:

Re: e701i-a3 no picture but backlights
Actually after thinking about it I do plug in the ribbon cable to the tcon so it can power the vertical lines. Correct?
For some reason having a hard time attaching the pictures to this post. I’ll keep trying.Leave a comment:

Re: e701i-a3 no picture but backlights
Alright, new transistor installed right side ribbon disconnected from tcon and also disconnected from right bottom front corner of tv. I will peel the ribbons off the right side front of panel tomorrow. Question tho, after peeling right side ribbon off panel, there is no need to plug in the right side ribbon cable into the tcon board..Correct?Leave a comment:

Re: e701i-a3 no picture but backlights
My first post exsplains. I replaced the tcon last year. Purchased from eBay for $20. Worked for 15 seconds and died again. It went back to blank screen with back light. Waiting for the transistors now. Hopefully will get em by the weekendLeave a comment:

Re: e701i-a3 no picture but backlights
Oh sorry about that. I de-soldered(removed) the bad transistor off both of my T-con boards.
Ok, that is what I ordered last night from mouser. Can’t wait to fix this boy but like you, I am nervous about peeling those ribbon off that panel. I will Be thourough in my testing before peeling the ribbon off panel.Leave a comment:

KevinM, first off, congrats on the working tv and thanks for posting that video. It’s very helpful. I plan to order the new transistor tonight so I can get this thing up and running. Just curious where you purchased the transistor? I have already disordered the transistor off boath boards.Leave a comment:

Re: e701i-a3 no picture but backlights
Hi guys, first time poster here but been stalking since last year. WOW!! You guys are incredible!!! Geniuses I say!!! Well, Here is my story. I have read this a few times. First time can be a bit confusing but second time makes better sense. I was given the Vizio 70 by my brother about a year ago. He works for a real estate builder and this TV came out of his model home. They were gonna land fill it and being the fixing tinkyer I am, of course I took it. Needless to say this tv sat in the model home all day “ON”. Has all the same issues,...Last edited by Dirtyphinger; 01-31-2019, 08:25 PM.Leave a comment:

Re: New Members - please post your introductions here
Hello All. I am from Belgium and live in Florida. I work as a property manager. I have alway enjoyed fixing things ever since I was a kid. If I can learn how to fix electronic or get a better understanding how they work, that's a win win for me and hopeful some friends and family. Hopefully I can contribute to the comunity as well.
Thank you
