Check the internet. Most likely a series of cheap capacitors. Replace them all (the ones that match the culprit). ~.20 each US.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
For CCFL type back-lighted sets, if any CCFL tube has failed. this kind of fault (horizontal shadow) will occur. These lamps are replaceable.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

You might want to call Samsung with the model number as I remember seeing a notice for certain models that have this issue---a jumper plug needs in those sets to be removed that is located on the power board.

Sound like you might have a high voltage ribbon going to the picture module arching. Turn the Volume down and put your ear close to the edge of the set and see if you heard a arching or a high frequency pitch coming from the side or top..

You have measures the cable coming in , go from the center conductor to the braided ground sheath, I really think the problem is with the cable not the TV.

Something else got damaged during your "adventure." See if U can get a schematic for your set and trace the power going into it. Maybe the main PS is not really being turned on because the relay that needs to be powered is not getting any juice. Happened to me with Sony cd changer. Check out the source of power to your PS relay - in my case the secondary transformer that powered the low voltage circuits had an open primary winding!
When you turn on the set you should hear a click - if not the relay is not working!

color circuit is out, try banging the set on the frame with the palm of your hand to see if color comes on or fluctuates, if so you have a loose component which is only fixable by you if you are really knowledgeable about the inside of a TV
