Repair Samsung LCD TV -Relay Clicks, Shuts Off, Won't Come On

Step 5: Replace the repaired power supply and attach the rear cover

Replace your newly repaired power supply, connect the internal cables to the other components.  Re-attach the rear cover, stand (if used), or wall mount brackets. Attach the external cables (Video, Antenna, etc.).  And, finally, plug in the power cord.  If all has gone well, press the power button and you'll see your set power up as it did when it was new.
