Question about Televison & Video
Most shops have a remote tester----have it tested (usually free).
Also , most digital camera's in a very dark room will react on the display screen with a flash when the remote is pointed at them and buttons pressed---home check.
If remote is not sending it can usually be fixed---IF remote tests out as good the REMOTE receiver in the unit is bad.

I hope you have done the following other than changing batteries.
Polarity - Check the batteries have been placed properly' Cleaned the terminals as they become ineffective due to moisture and dust. The moisture can come at times from wet hands which some time we do. Hope that liquid/water has not been dropped accidently on the remote which makes the circuit inside the remote ineffective. Blow compressed air inside the remote to clear the dust and moisture inside the remote. If still it does not function there is no other alternative but to replace the older one.

To make sure the remote works or not. See if it blinks if you shoot the pointy end to a mobile phone in camera mode. If it's working fine there, some other issue. At least you know if it's a battery thing.

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.
All these can be checked on the power supply board.
But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I hope this helps.

Check for rusted battery contacts due to leaked batteries. Clean them with polish paper or blade. Due to leaked batteries it is quite likely that the wires connecting remote control pcb & battery contacts are cut off.

SOURCE: Remote won't work. Tried new
To confirmed if the remote control is working fine, aim the remote control sensor(IR emitter) directly to your cellphone camera. While pressing any button key on the remote control, you can see the flash of an infrared emitted by the remote control if it is working fine.
If you've confirmed that the remote control emitted an infrared but still the tv won't communicate with it, this is an indication of faulty IR sensor board of the TV. Check if there's an obstruction from the IR receiver in front. Keep away all of it, clean the plastic window of the IR receiver with soft clean cloth.
If the symptoms still persist, you have to replace the IR sensor board. Check the actual part no. of the board before ordering.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
