Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.

Thats a common problem thats almost always caused by failed capacitors on the DM powerr board. You can get the WS55859 DM repair kit from www.tvrepairworld.com the kit contains the upgraded capacitors and the CD with repair instructions.

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
I hope this will helpout ......

Not much info to go off of, and the video is a bit blurry. Try unplugging the tv for a minute or two, make sure to leave it unplugged to allow power to dissipate. Then try again. Otherwise I would suspect power supply problem.
