Re: e701i-a3 no picture but backlights

Re: e701i-a3 no picture but backlights
So I thought I would try and fix another 70" as I had success the first time but I have ran into a problem, quick version.
after removing tabs, new t-con tv is now working again but the screen quality isn't very good real pixelated / gassy looking pictures attached. I have tried cleaning all cables changed setting but nothing seems to be helping. 
Thnaks...

I might have spoken to soon after watching a couple videos on the tv then it developed lines down the screen all the way across and now does not go away. :/...Leave a comment:

Ok so update, picture one is with just the left side connected. (did have a little scare when I tried it and nothing showed but realized the ribbon cable wasn't seated right.
)
So after removing the right side boards and drivers I now have a working TV again..
Last two pics of working TV.
Thanks again for the help....Leave a comment:

Yes all tcon cables are plugged in and at this moment neither one of the corners are plugged in, so when I get home today I will now try connecting the left one only and see what happens. Just wasn't sure if with both sides disconnected I should be seeing the lines instead of a faint picture.Leave a comment:

Re: e701i-a3 no picture but backlights
Thanks for the great post have read it several times now, but I do have a question in hopes I can figure this out. So after purchasing a new TCON board with both bottom ribbon cables disconnected on the sides I'm just getting vertical lines that do move with menu button and I'm guessing the V logo when starting up but no actual picture. I did connect the bottom right cable and had to replace the coxa chip so before I do anything again this is the point I'm at.
First photo is when turning on (logo I believe)
Second when...Leave a comment:
