I have a Samsung Ln40b530p7fxza. The screen is like a photo negative, mostly white no dark colors in it I can barely see the screen. Sound works fine. So I took it apart and saw a inverter transformer burnt so I bought one and replaced it. Still has the same issue. So now I want to replace one of the two inverter boards on the edge of the tv because i see some corrosion on a couple resistors or whatever they are. But I can't find a way to take the board off. All my searches come up saying remove the wires and take it off. I take the ribbons off the TCON? Board, but there are ribbons connecting the inverter boards to the screen and I see no way of taking them off they look permanent.

One more thing after replacing my inverter transformer I now have a high pitch noise coming from it?

Thanks

GOOGLE - Your search - L40b530p7 - did not match any documents.

Suspect you need something between the 'L' and the '4'

Both the Tcon and inverters are removable. If you Google the particular board number(s), Shop Jimmy, Ebay, etc. will show pix of board which may allow you to see where your becoming stuck.
From my searches, without board number confirmation, tcon 3 connectors, two roll-type latch/lock and 1 push/pull ... inverter 2 connectors for different boards with 10 parallel push/pull bulb connectors. We both know you removed mounting screws.

crappy picture but I already put the tv back together. As you can see these ribbons dont have connectors. I don't want to yank them and maybe break something. The ribbons go from the board into the glass.

That is part of the Panel - DO NOT mess with them, (broken contacts with those are what cause pesky lines/bars etc.)
