No lcd image, dock is perfect

Hello everyone! Couple month ago Ive got nintendo switch with no lcd image. I found out, that couple pins of lcd connetctor was bent. I ve changed lcd connector, but no luck. I also checked it out with other screen, but got same issue. I do have both +5v and -5v on caps around lcd ic. I do have some other ic8316 to replace, but Im not sure if I have to. Help me please

p.s. There is a backlight. Sound, touch, dock and games work perfectly
