Hi, Not usually especially if the remote had a sleep timer button. the only excception is if the tvis fitted with buttons for accessing/navigating the menu functions from the local keyboard.
A quick way to verify if theremote is outputting any IR is to view the front of the remote with a digital camera/ phone camera etc whike pressing a button. you will normall see a white flickering light if all is well. note this doesn't confirm if there is good signal - more only an indication the remote is operational

First, here is a copy of your manual in case it is missing.

Next, check the settings of the sleep timer.
Select on the remote:
Menu.
Timer.
Sleep.
See if there is a time setting in there. You may also find a shortcut from the remote labeled "Sleep".

If this fails to resolve the issue, you can always reset to factory defaults. To do this, select from the remote:
Menu.
Setup.
Reset.

Hope this helps. Be sure to let us know how this helped.

go for a multi Brand remote ....

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!

check the sleep timer make sure it is off or set to 00.00 could be set for turning tv off in 15 min

your tv may have ben magnetized by the lightning strike.
tv's have an automatic degaussing circuit that demagnetizes
the pix tube when the set is turned on. this degaussing circuit
may not be working or magnetism may have been too strong for
the internal degaussing to correct.
contact local tv repair shop in your area see if they can manually
degauss your set , it should be a min. service charge around $25.

Setting the Sleep Timer The sleep timer allows your LCD TV to automatically turn OFF after a given amount of time. You can set the sleep timer using your remote control or through the onscreen display (OSD).
TO SET THE SLEEP TIMER USING THE REMOTE CONTROL
1. Press the SLEEP button on the remote control. The sleep timer appears at
the top of your screen.
2. Press the SLEEP button one or more times to select the time you want.
3. Press the EXIT button to hide the sleep timer display. Your sleep timer is now running in the background. The sleep timer will be hidden after 10 seconds.
Turning On the LCD TV.
1. Press the MAIN POWER switch in the back of the unit (see Back Connectors for location). The Status LED on the front turns orange
and your LCD TV is ready to turn on.
2. Press the POWER button on the front of your LCD TV or on your
remote control. The Status LED on the front turns green.

Sounds like it may be something you did. Have you checked to see if you accidentally put the sound on mute? Try hitting the mute button on the remote control. Also, if the TV has the option to turn of internal speakers (which you would likely find in the menu under audio settings if it does) make sure they are turned on. If these checks fail then we have an electronic problem to deal with.
