Fault with the main power supply regulator 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. Surf the site with patience. Pull up older posts.

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.

When tv is unpluged and pluged back in it wont power on and no lights blinck


Sure the plug is getting power from wall outlet? If power is there you might want to check out the power supply board first for issues.

Try doing a power cycle, which can be done by unplugging the TV, leaving it unplugged for a few minutes and then plugging it back on and powering it on. If it still doesn't turn on, I would seek repairs.

No power to tv


I would suspect bad capacitors on the power supply. They drain when left unplugged from the power source and then when power is restored the weakcapacitors cant recharge and the set wont power up.
