Unplugging it from the outlet for about an hour to let it reset itself first, if it still does not work then It may be in the safety shutdown mode due to short circuits in the power supply or in the backlight inverter board, you can try disconnecting the power cables to the backlight inverter board to see if you can get the TV to come back on with sound but no pictures.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Hi,
If red light blinks 3 times when tv refuse to power up then check lamp cover that was removed to replace lamp, make sure lamp cover is fixed in its position securely and screw is tight.
Let me know how many times red light is blinking after three second long pause IF it is not blinking 3 times.
Thanks.
