SOURCE: Hi my tv fell off
After a fall like this (even on carpet) it probably has a cracked circuit board or a loose connector, first (since you took it apart any way) look for all connectors, than unplug them and re-plug them to make sure all plugs and boards are seated correctly, if you still don't have luck, than take out all the circuit boards and check them for cracks under a good lamp and magnifying lens, than repair the cracked traces with a good soldering gun by scratching off the varnish coating and applying solder. (if the crack is to wide you can solder a peace of coper wire to the trace on the board)

Testimonial: "Thank you for the response what circuit board the power board? I I was to change that out how would I make it safe not to shock me "
Faulty parts on PS board , bad press for Samsung
When checking the capacitors, If they are slightly rounded on the top where the X is, the cap is defective.
Because the Samsung LNS4051D would not turn on and the power
LED would blink 4 times and the relay would click and this
would repeat again and again. I replaced power supply board
parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors,
three had their tops bulged up slightly that I missed on
initial visual inspection. After seeing the reports of
problems with these caps on
I replaced them with Radio Shack part 272-1032, 1000 uf, 35v.
They are slightly bigger, but fit OK. TV is working fine now.
Cost was 4 x $1.59 = $6.36 plus the time. I saved between
$100 to 300 in the process of either replacing the board or
getting the unit serviced. If you are not comfortable
replacing components which means using a soldering iron, you
can replace the power circuit board, available from
Some UTube showing the problem and fix
