The first thing to check is if your power outlets have surge protector breakers. Try plugging in another simple appliance like a lamp into the outlet and make sure the outlet has power.
If the outlet is fine try plugging in the TV and listening very carefully from the back of the TV for a subtle click noise. The power supply has a mechanical relay that switches when the TV receives power. If you can not hear the click and there are no stand by or power lights illuminated then you likely have a power supply problem. This could range from a blown fuse to a bad capacitor up to a burnt out power regulator. Anything more serious than those problems may warrant simply replacing the whole power supply. Depending on your TV that board could cost anywhere from $50-$175. The power supply can be tested using a multimeter to determine if it is the source of the problem but this should not be attempted unless you have some electroics repair training and are aware of the dangers involved in working on high voltage electronics.

If you have a meter and know how to use it Google for the service manual online and start checking. If not head for a tech or a shop to examine the TV.

Hello sorry to hear that. From your description it sounds like your signal board may have been damaged by you plugging in your laptop to it. The signal board is the one with the tuner on it.

i have the same thing but what i do is unplug the tv and plug again till i hear a click then replug immediately and wait for the tv to come on .this is normally a symptom of a weak surge protector in the back, inside of the tv.it is normally not an expensive repair and better still if the tv is still on gaurantee it should cost nothing.

The tv power supply board is is problems and the causes.That the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

unplug the television...wait 10 seconds and then plug back in....if you listen carefully after 5-10 seconds you will hear a click sound (the same sound that you hear when you turn on or off) ...once you have heard it, turn the TV on again using the remote. Do not turn on until you hear the click. If this does not work, try again but turn the TV on again before you hear the click. I dont know why it happens but it is as if the TV gets confused as to whether its supposed to be on or off. Most of the time, the solution is to turn it on after the click so I would always try that first.

Bad caps in the power supply must be replaced .

Its a power supply problem you can change the board and it should fix the issue
