Samsung UN55C7000WF, front standby light is lid, indicating power on power supply. When I press power, standby light goes out, then power supply relay clicks on and off continuously until unplugged. Power supply looks good, no bulging caps, blown fuses or shorted diodes or transistors. Shop Jimmy has a repair kit for the power supply, don't know if this will help me. I'm leaning to a bad main video board. Looking for a more positive answer, your thoughts. Thanks in advance for your help. Victor

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.
