Horizontal Lines on Vizio E601i-A3e?

[ajsterr4]

I bought this TV on craigslist who said the back light didn't work, but it did and all (I thought) it needed was a new TCON - there was sound, but no picture.

So now I have a new TCON board in it and I get a perfect picture, but there are a few horizontal lines towards the bottom... Bad panel? Is there anything I can do to repair?

Am I missing something small?

Edit: One picture is blurry because of my camera movement

the horizontal lines show up OK... :-) :-(
the bad news is that on this set, those lines can't be fixed and further, it is likely that it will take out the tcon again... actually one of the fets on the tcon which can be replaced but as I indicated, you are fighting a losing battle.

Update: Lasted 20 mins after new TCON was put in. TV went black

Bud, I bought some beefier transistors for the COXA/COTA replacing... By fet do you mean this one? The MOSFET?

If I switch out the transistor for a better one do you think it can last and I'll just deal with the lines?

That's basically your only option to get anything out of the set. As you see in other vizio threads, "beefier" helps... BUT ultimately the tab drivers that are causing the lines will continue to be a bigger and bigger issue. Only with the 70in sets where the tabs are removed from the side that is in trouble is the set "salvageable".

So after the TCON failed I replaced the transistor and boom, TV shows image again and its been on for about 1 hour, however one side of the screen is darker? Before I had a perfect picture with the horizontal lines, now lines plus darker image on one side.

Did I maybe mess something else up on the TCON?

Ya BUT.... I guess you probably "proved" why they (vizio / sharp) choose the component that they did. :-) :-( There are probably a "few characteristics" that you didn't consider / know that are different. My guess, you are seeing some form of "loading" on the device that lowers it output just a bit resulting in "less than full powering" horizontally.

double check your cable connections as potentially they might not be seated properly. The picture is somewhat similar to a 70 in when on of the side corner cables is disconnected... of course, you don't have those as this set only has a lower set of boards.
