Hello guys!
so there's Samsung le37m86bdx/xec which arrived with defect - switched off after a while. Solved that soldering the contacts which seemed to have micro crepes. Now it goes negative after few minutes of working should i check t-con? resolder chip contacts or just change it? Thank you!

Check with your finger if the as15 is hot. Replace as15 or tcon
