I press the sleep botton and off the tv when i on it the red light will of but the screen dont come

Hi. i believe this to be either of these three problems.
1. Power: it could be that there is a problem with the power electronic element(s). the solution is to go see an engineer.
2. Screen: if the television uses LCD display, it could be a problem with the liquid in it. Solution is to see an engineer.
3. Sleep mode: the TV could be in sleep mode which makes the screen go blank until removed from sleep mode. Solution is to read the TV's users manual to see how to wake a sleeping TV. Get back.

HERE'S THE ANSWER TO YOUR PROBLEM:

I think the problem has nothing to do with your TV. I bet the culprit lies on the setting of your remote control. Maybe you set your remote into a sleep mode. When a TV has set into a sleep mode. It's power on light is still red but doesn't work. So all you've got to do is keep pressing the sleep button. After a few presses, it will definitely work. And, you can now enjoy your day watching TV. Thanks.

-as usual; try to start tv with the power botton on set.
-press and hold tv botton on remote untill the led light stays on
-the with the rate of one second press on/off botton on remote, aim the remote at the set
-when the tv set goes off immediately press enter on remote.
-this will program your remote, but still you dont have the code for the future when changing batteries.

PANASONIC..PT-52LCX15. STARTED TO A LIGHT COMES ON THE SCREEN. THEN TWO LIGHTS. FINALLY TV DONT COMES ON. I PUT ON THE TV, AND ON BOTTON START BLINKING AND TV DONT COME ON..I TAKE OUT THE TV LAMP..IT LOOKS GOOD NOT BURN. SHOULD I REPLACE IT??

The following instructions are for the Emerson EWC1303/1903 tv/vcr. That's the closest match I could find to the Spongebob Squarepants 13' TV
If it's actually in Sleep mode, do the following:

TO CANCEL THE SLEEP TIMER
Press the WAKE UP/SLEEP button on the remote
control until “SLEEP TIMER” appears.
To view the time left for sleep timer press the WAKE
UP/SLEEP button twice, then press the MENU button
on the remote control to exit the sleep timer setting

If unsuccessful, try unplugging the TV for 1/2 hour, then plug it in and try turning it back on either manually or with the remote. Either of these should solve your problem. Best of luck to you!

I was here originally with a problem identical to one posted and found that the best solution posted was only partially working. My husband and I were able to get the tv on but that was the extent of it. Once on the remote was not working. Out of frustration we figured out the that if you practice the exact steps after the tv is turned on, 
1 hold the set button untill the red light comes on 
2 press what you want to set (tv,vcr,dvd,ect.)
3 press power botton aim at unit and wait until it turns OFF then quickly press ent.  This did it for us and we are now happily watching tv again without having to toss our beloved giant remote into the garbage. Hope this helps!!!!

press and hold the tv botton on you dish remote till all the lights light up release the tv botton it should stay flashing then hit the larger of the two red power bottons next you will need to hit the up arrow one at a time till the tv shuts off when the tv shuts off you then hit the # botton at the bottom you wiil see the tv botton flash your code will then be saved

I got this same tv from a guy in my area he would press the poewer botton on the tv and the standby light comes on and then turns off, so he gave me the tv for free i took the back panel off, and everytime i press the power botton the green light came on where the screen board is and went back off after i let the botton go i took the power board out took it to a repair shop to see if there was anything a wrong with it everything was good so i replaced the two fuses on the board and the one on the screen board, i had a feeling about the power switch so i jumped the wires on the switch purple to purple and green to green, I put it back together pluged it in the standby light came and stays on now, so i went out and got a universal remote for the sva at walmart for $15 programed it and pressto the tv works perfect so three fuses $3.60 two small pieces of wire and ele tape $0 my time 35 mins = one working plasma for $3.60 so when you have this problem like everyone else check the power botton switch, there cheap and check the fuses theres only three and if that dont work idk what to tell ya. and you do need a remote or tv wont work.

Solution is simple....

First, unplug power cable from the back of your TV. You will notice the flashing light is still flashing. Don't worry, go to the Second step.

Second, keep pressing on the POWER button, located on the panel at the top of your TV, to shut off your TV. This will stop the flashing light from appearing.

Third, Plug the power cable back onto your TV

Fourth, press the POWER botton ONCE, using the same button used in the Second step to turn your TV back on.

Fifth, you will see the POWER light comes on, as normal.

Sixth, using your remote control, press the green button to turn on. Your TV should work as normal.

The pilot light is in blue or red??
Is blinking after turn off??
