Hi my name is ***** ***** I will be the expert working with you today to help and resolve the problem you have posted.
Unplug the power cable from the tv and then try to push and hold down the power button for 45 seconds on the tv while the power cable is disconnected.
Release the button and plug in the power cable back and try to turn on the tc using the remote.
Before trying to turn on from the remote try to remove the battery of the remote and put it back in after 30 second this will reset the remote control.
Please tell me the model number of the tv.
how old is the tv?
after trying power cycle is the led light still blinking?
do you see any error message on the screen.
When there is no error and the light is blinking that means the tv is receiving power input but not enough power to power on the inverter and the backlight which can lead to a power supply unit failure and it can be the inverter board as well need to be checked using voltmeter after getting it opened.
you can contact a nearby tv technician and get the tv checked you can carry the tv to the repair shop as it will not cost you for an engineer to visit and check then charge you for the visit as well.
You can get it repaired, buying a new tv will be a costly affair.
