'''JCE138'''  this does not look like a typical T-con issue at all, but it is possible that this is related to a bad Gamma correction IC. Some TV’s do have those on the T-con board. At this point you can try and see if replacing the T-con board will fix it. This T-con board apparently has issues with the Gamma Correction IC and replacement IC’s etc. are being sold separately. The board is a Samsung 35-D025860 Post some good pictures of your boards with your question so that we can see what you see. [guide|21499]
 
=== Update (06/16/2019) ===
The IC in question is labelled AS19-H1G and here is the datasheet for it [document|5637]. This will allow you to check the voltages etc.
