Yes it is under the bracketing, and while your picture was a little fuzzy, lacking critical details like screws..you have to remove the center bracket while the TV is laying on a table with a soft blanket protecting it. Then you remove the bracket. Then that metal cover has to be removed, and it looks like it's a one-piece cover that covers the TCON and the main board. Usually the screws are only around the outside edge of the cover, but any connections poking out the back of the main board may have 5mm nuts that need removed. I only find that on computer jacks, and HDMI on the back or sides may have #1 Phillips screws holding those to the metal cover.
Also note that Shop Jimmy page I sent you with the 3 different TCONS ... it didn't state they were out of stock on Saturday. You may want to match your Tcon to the correct board, note the actual part number, and consider buying it.
Now the nice thing about Shop Jimmy is that the page I sent has ALL the information you need for that. Read the whole page, you'll note that they tell you how to get the correct part. AND if you double click their picture of the part (twice), it enlarges to see the sticker and the number on that sticker highlighted in pink. They don't want to ship the wrong part to you, so they're meticulous about that.
I'll look at your pictures, see if they help us, ok?
Good Lord, this may be a lot of shield removal. I replaced a Tcon on a Sharp years ago that was like yours...the OLDER units (pre-2007) were just plain overshielded. Feed back some details about that to verify, but you need to look at the picture to get us both up to speed. And I will be in and out all day long today, got to get groceries, new work shoes, clean the house etc. But I will check back all day long, ok?
Hmm, my paperclip button is grayed out...Oh for the love of Pete..I may have to post another response to get the picture on here.
