On each side of the actual screen there can be a series of COFs protruding a short way -they are fused into the glass screen with an end hanging out unattached.
Nothing to do with the t-con or strips along the bottom. these COFs have connections running inside the screen. You'll need to remove the cabinet front (bezel) to access them. Only do the ones on the bad side.

Thanks for the response again. I got some time to check the screen again but I'm still unsure as to what to look for.
By any chance, is there a youtube video or something showing the process you mean?

I also ordered another Tcon board - and the lines continued to show after replacing it unfortunately..

Could find nothing on youtube, but it's discussed a fair bit on Badcaps Forum.

Thanks Bruce,

I'll try opening a thread regarding the issue there.

But if by any chance you do get another Sony 55 to repair yourself - would it be possible to take a few pictures of which you mean and share them here?

Thanks again for the help

Sorry to report that I just stripped one today and it's gone to the recyclers, but I can report that it had NO side tabs, So scrap the idea of removing them. I would now venture to say that the panel has some internal fault, but just to be sure, check the data strips along the bottom of the panel for any shorted surface mount capacitors on the bad half. Both strips will have some similarities, so you should be able to do comparisons. You need to remove the black metal strip across the bottom of the panel (screws) and then remove the metal cover over the bottom strips to access them.

Hi Bruce,

Sorry I hadn't noticed that there had been a response - thanks for the help again, but so far no luck
