Re: Samsung UN40D6000SF
Connect one side of the tcon to panel ribbon cables one at a time and see if one side displays a good picture. If so, you can try the tape cutoff method on the bad side by blocking the outer pins with scotch tape. -

Ok, so with the panel face down, unplugged right side, left side looks good. Switched and bad on the other. Tape on which end and how many pins should be covered.Comment

On the bad side, tape over 2-3 pins to start on the outside edge. Increase by a few more pins at a time. Repeat if picture is still bad. Unplug tv between attempts. If still bad, you can rip off the side tabs on the bad side if it has them as last resort.Last edited by neilc6; 08-27-2020, 08:15 PM.Comment

Re: Samsung UN40D6000SF
The photos are not so good, if screen is in landscape position the camera must be the same, if i see well there's a top portion well visible and a line that divides the bottom doubled image. If yes try to insulate with tape first CKV1,CKV2,CKV3,CKVB1,CKVB2,CKVB3 in turn, if it doesn't work try VCST,VST, VSS in turn. Theese signals are repeated in both connectors.Comment

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
