Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

OK guys I'll save you. The tv is in hotel mode. To get it out from there you have to go in service menu but DO NOT CHANGE ANY OTHER THING IN THERE, only what i tell you. With the tv on and the K letter on the screen press in the same time vol- and ch- on the tv set. Now you'll be in service mode. On the remote press down arrow (not -channel) and you'll see up industry init. go there with ch- and press vol+ and enter. let the tv like that for few seconds and the tv will go green and hopefully industry init succsesfull will be on the screen. After that unplug the tv and replug it. Done!
I have a brand new
While the set is turned on, you need to hold the power button until the set shuts off and the led in the middle of the bottom flashes once. Then quickly release the power button and press the vol - and input buttons together along with the power button. Your TV should then turn on and should show you a blue box with the letter K. Now press the vol- and channel- buttons at the same time. You should now be in the service menu. With your remote arrow up until the top line says industry init. Arrow to the right and hit enter. Screen should turn green and say factory init success. I hope this helps you.

One transistor out of millions has failed shorted. That is an unusual failure mode, but not unheard of. The chip can probably be replaced, you might want to check google maps or http://tvrepair.com
for a repair shop near you.
Most shops should be able to give you an estimate, I would guess around $300, unless the chip is hard to get.
We have over the air T.V. On digital channel 9.1
switch TVs and see what happens. If the problem now occurs on the old TV, it is the TV. If the problem occurs on the new TV, it is the location. But use a ground fault tester in case that socket has some kind of ground fault

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
