There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both - in your case, it's most likely the power board section.
Any caps in these sections (or any other for that matter) that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't, and it may already be at that point !
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors, and it spans most major brands including Philips.
The parts are cheap, and skill required is minimal.

Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Good luck in solving the problem....

Give this a go
1 turn on the tv you want to program to work with the remote control. hold the remote in a straight line in front of your tv at a distance of less than 1 metre.
2 press and hold down the remote device mode button (tv) and the (power) button at the same time until the red light indicator lights constantly.
3 press the power button
4 the (tv) button will blink continuously in red meaning that the remote is searching for the code of your tv.

6 by pressing the (ok) button you have already stored the code. the (tv) button light will turn off.

Tip

Lamp Time Reset for Samsung TVs


This is a quick reference guide to show you how to reset your
Samsung DLP TV’s lamp hour meter or hour counter.
Resetting the counter is a very simple procedure.


Begin with the TV powered off


Point your remote towards your TV


Press:
Mute + 1 + 8 + 2 + Power


Your TV set should now say “Loading Factory”


Browse down to “Option” then press Enter
(or the right cursor button)


NOTE:
The Mute+1+8+2 buttons needs to be pressed down consecutively and fairly quickly. If your TV does not enter the service menu after using this combination, you can substitute MENU instead of MUTE. I think that’s a better way to do it.. Also, the right cursor arrow also acts as the ENTER button, so try it if you’re having difficulty with the ENTER button

To exit the service menu, hit press the EXIT button or just turn off your
TV (remember not to turn on your TV immediately afterward!)

The blue light merely indicates power is getting to the TV. When you press the power on button, the defective power supply shuts the TV down immediately

Can not get the power button to shut down the computer no matter how long I hold it down and the computer appears to stay in hibernation. Will not reboot or do anything when power is applied and power...


Remove the battery and leave off for about 1 minute. Put the battery back in place and press the power button to turn the unit on. immediately after you see system light come on, press and hold the power button and see if it shuts off after a few seconds. If not, then its likely your motherboard is defective.

Need codes to program a dishnet remote to a emerson tv


Turn on device you want to control (TV, VCR, DVD)

Press and hold the CODE SEARCH button until the red indicator light remains red, then release

Press the desired mode button (TV, VCR, DVD) and release

Press the POWER button slowly, but repeatedly
until device turns off. While doing this, the red indicator blinks then stays lit

Once the device turns off, press and release the Enter button to install code. The remote should be synced to the device.


Another view:
Someone on another board pointed out that with some newer models you do not need to press the CHANNEL UP button repeatedly. Rather, you press it only ONCE, and the device will cycle through all the code possibilities. When the TV turns off, it means that the proper code has been found. Immediately press the Enter button to install that proper code. This method (and no other) worked for me.

I need the codes to program my Innovage Jumbo Universal Remote for Dynex television


As there are no specific codes for the Dynex TV you have the choice of either using the Auto or Learn method. The following are instructions for both:

AUTO Method

1. Press & Hold (about 3 sec.) the [DEVICE] button on the JUMBO Remote....llight will stay solid.
2. Now just press the [POWER] button (only) ONCE while pointing at the device...it will start sending codes approximately every second. (Don't keep pressing the power button as instructions indicate.)
3. TIMING IS EVERYTHING HERE. (It may take 5 minutes to find your devices code.)
4. AS SOON AS the power goes off...press the [ENTER] button on the JUNBO Remote.
5. Now pressing the [POWER] button should power up/down the device.

---- any buttons not programmed will have to be handled using the LEARN method ---

LEARN Method

1. Press & Hold (about 3 sec.) the [DEVICE] button on the JUMBO Remote....it'll stay solid.
2. Press the [LEARN] button on the JUMBO Remote. (light will immediately blink rapidly.)
3. Now Press the {NEEDED} button to program. (light will stay solid)
4. Now (1 to 2 inches away) have the ORIGINAL Remote pointed at the JUMBO Remote and press the {DESIRED} button on the ORIGINAL Remote.
5. It blinks rapidly while sending...then a slower steady blink once "LEARNED" correctly.

*** Not all buttons work properly with the "LEARN method". Some you will need to "associate" with an alternate button on the JUMBO Remote. *
