Dulan Wijesundara this is the same Samsung UA55ES8000 TV where you repaired the T-con board? Besides the thick band it also looks like you have multiple small lines running vertically down the screen.

Dulan Wijesundara check the ribbon cables going from your T-con board to your panel. Make sure there are no small tears etc. Check that they are inserted straight into the connector and that the connector makes proper contact.

Update (12/01/2017)

Apply some gentle pressure on the TAB's and see if the image changes.

i did check the both ribbons. all are fine... do u have any idea to check these panel ribbons i have added photos..

Those are the TAB that connect the LCD controller to the LCD. They are bonded (special glue simplified)to the LCD. Not much you check on those. If they have failed you get vertical lines but usually not a large block of not working. The black line means your panel does not receive any output from the video processor.

I did pressure all tabs are located s@ the panel.. but nothing got changed.. can i another way to check TAB ribbons working or not.. that mean power going trough the ribbon? Please let me knw .

Only with a oscilloscope etc. If it did not change anything then it is most likely not those cables. The signal to those cables comes from the main board to the T-con board. Most commonly it is the LVDS cables that are not carrying the signal.
