Pssh!

Its the fricken Zebra cable connecting the very last wire to the LCD panel-The thin cable soldered directly to the glass panel.

Try pushing lightly on the plastic bezel under the missing line. Does it get better?

Try pushing lightly on the LCD panel. Does it get worse?

You'll probably have to actually lay it on its back and remove the bezel around the screen, then push very lightly on the very thin and delicate flat cable connecting the TConn to the LCD. A rubber eraser may be helpful. If it goes away then the solder joints have separated. The only way to fix it is to use a hot air gun or soldering iron to reattach them while pushing down lightly, gently and carefully(basically on the edge of the glass!). Silicon would be helpful here.

This sort of job is best left to an experienced professional. the manufacturer uses a long tool that pushes down and heats up the solder.

:-))))
I think the "other guy" was asking for pictures of the back of the set WITH the back cover removed.... :-) so he can see what's happening with the cabling.

Re: Rca picture in half??

kinda looks looks like the transmission is set to sbs 3d mode... are you sure the lcd panel tcon cables werent installed backwards somehow?? that or its set to a different panel type in diagnostics.those rca branded sets use the same main baord numbers for many different model tvs with different firmware and sometimes hardware... I had a 50" I repaired give me grief because a seller of the replacement mainboard made and assumption and sold me the wrong board.... you have to be sure the serial number range matches the part number for the board and not just the number printed on the board itself.

Re: Rca picture in half??

In order to properly diagnose your TV we need clear pictures of each board in the back of the set which means removing the back cover. We need good clear pictures of mainboard LVDS cable, tcon board including cable connections going into the LCD panel itself. This could be a fault with the LVDS cable or the tcon board or the main board sending the output signals into the tcon to the LCD panel
