Double purple image after backlight repair (SAMSUNG UE55KU6472)

Hi, I recently tried to fix this 55” Samsung tv, on which i could see image using flashlight only. I used backlight from UE55HU64** tv with the same ( looking ) LED backlight. After installation the tv went into bootloop without any sound or logo for Split second displayed. Only backlight went on bright/off/dim and tv restarted after this.

I tried using the tape to block some signal to the right side of display. This led to tv to boot but with some defects on image (vertical line right in the middle of the screen) . So i removed the tape, where to my surprise tv booted but image looks like this.

Any idea what mať be causing the problem here?

Thanks

@michal99487 looks like you still have a backlight issue. I really would try and find the right strips for the panel. As for the right side (looking at the picture) this is commonly a panel error (driver boards). Double check the ribbon cables and connections. Check for tears corrosion etc. You did not tell us if this defect was present before your replace the backlight strips (that would explain the tape off)
