    Just replied to your pm- drop me an address and I'll send you a couple - I guess I didn't mention it is Mouser where I got them… but we need to thank freakaftr8- he's the one that came up with what the altrnative transistor is.

          Glad to help! Don't forget Tom66 and Budwich! He was onto this fix as soon as I was and Budwich was the first test candidate after my success. This "operation" applies to any large screen tv with a failed Sharp made lcd panel I presume that fails in the same manner as long as it has drivers on both sides.
          Did I leave the soldering iron on?

              I think this might even "fix" some Samsung sets with various similar issues. Worth a shot...

                Add the sony 70 inch to the list. Just got one in from a customer tonight. Same issue. I'll be removing the right hand tab drivers tomorrow.

                This one shutdown with 5 flashes. See the beautiful white line after ddisconnecting the lower ribbon on the right tab driver board.

                Of course I'll let the customer know this is not for say a fix but buying time.

                Note pictures are taken upside down.

                      Re: e701i-a3 no picture but backlights

                      Hey freakaftr8 I have been following this thread with you guys tring to fix my Visio e70 as well. So far I have replaced the mosfet chip as described and do have a picture but the V in the center of the screen is somewhat distorted while everything is plugged in. When unplugging the right drivers (3/4 inch wide white ribbon right side front facing) I get about a 2 inch tall stripe of vertical lines from the center of the screen to the right? Any suggestions. Oh I,m sorry I forgot to say Thanks to everybody involved in this thread it has been very helpful.

                            I'd like to add that I went down to my local Walmart yesterday to do some shopping with the family and there on the wall is thier biggest 70 inch TV still displayed is this exact same model and long and behold two nice bright white horizontal bars across the screen as the TV still working I know it's going to fail any day now. Dang Sharp. I used to have high hopes for thier panels but sadly we are starting to see a trend with failing side drivers. Crossing my fingers with my 80 inch on the wall.
                            Did I leave the soldering iron on?

                              Okay freakaftr8, I cleaned the white ribbon cables at the t-con board and get a better picture. now with the right hand white ribbon unplugged I get a solid 2 inch white line across the screen from the center. Bare with me on the picks I will have to have my 15 year old daughter help with the download of pics after 4. Again sorry.

                                Okay that's any better I have seen vertical lines associated with bad connections with the white ribbon cables in the past well actually there more like vertical bars in different varing colors

                                , so what happens when you leave everything connected to the panel but pull the right side white ribbon from the t-con board? you should see a picture on the left or you have no picture at all? Now do the same with the other side and leave the right side connected do you have a picture on that side?
                                Did I leave the soldering iron on?

                                    When you go to post a message you see the bottom button that says "go advanced"? Click on that click on "Manage attachments" then click on "chose file" find the file on a computer and then "upload" it once the file shows that it's uploaded click "close window" and then post

                                        ok. The side that is dark.. remove those tabs from the panel.

                                        That bright line going across the screen is a dead giveaway if there were nothing wrong on that side of the panel that line should get dark with the rest of the panel but its not which meaning its a breach in a connection
