K957ws500 stays on for about 30 minutes then the screen shuts off the light blinks on the display

You have a bad convergence board, or the TV processor has garbage in ti, and if you leave the TV unplugged from the wall, for 40 MIN. that will reset it back to normal. If that don;t work then it is the convergence board, unless if it turns real blue, or green before shutting down, then that color , the screen voltage needs turn down, then it will stay on. Or the red, blue, or green CRT is sorting out, then it is time to buy a new LCD, if it is a bad CRT. for a service call it will run around 70 dollars to find out. Take care.

Make sure your filter screens are kept clear.
Protect Components from Overheating
• Don’t block ventilation holes on any of the components. Arrange the components so that air can circulate freely.
• Don’t stack components.
• If you place components in a stand, make sure you allow adequate ventilation.
• If you connect an audio receiver or amplifier, place it on the top shelf so the heated air from it won’t flow around
other components.
Hope this helps!. Otherwise in your owners manual, under troubleshooting it states:
TV turns off while playing
• Sleep Timer, Wake-up Timer, or Watch feature may have been activated. Go to page 45 or 69 for instructions.
• Electronic protection circuit may have been activated because of a power surge. Wait 30 seconds and then turn on again. If this
happens frequently, the voltage in your house may be abnormally high or low.
• The sleep timer may be set.
• Unplug. Wait five minutes. Plug in again.
Hope this help you out.

TV shuts off on it's on after about 20 - 30 minutes of play

freeze like the picture is in pause?

picture freezing is desired function on the remote and handled mainly by the "picture and picture" circuits. but the video that is involved and processed there is handled by many circuits and microprocessors.
what you describe is an intermittent heat related problem if you almost can set a watch to the the shut-off time. you can feel, if your a tech, what part is running hot with a finger or start freezing a suspect part with freeze spray and see if stays on long past overdue. make sure your vent holes in the back are not covered and keep the back at least 1/2 foot from the wall.
