Question about Samsung DLP HL-P5663W 56" TV

3 Answers

My Samsung HL-S5086W DLP TV which is about 3 years old has started shutting off after being on for 20-30 minutes. I turn it back immediately and it then plays for another length of time. When it turns off it sounds the same as if I had turned it off. Bill F Jacksonville FL

We replaced the lamp on our Samsung 50" dlp model HL-S5086W tv about 3 weeks ago. Just recently, the tv started turning off by itself and the red standby/temp light and the green lamp light flash for a few...


    1. Ensure that the TV is off. It may be advisable to unplug the TV as well.
    2. 2 Using a Phillips screwdriver, remove the single screw affixing the lamp cover (the small, grill panel on the back of the set) to the chasis. There is also a grill that is held in place by tension. Just "pinch" the thumb clamp on the bottom of the grill and slide it out. This is the same procedure you would perform to change the lamp, except in this case you will not need to remove the lamp itself.
    3. 3 Inspect the spring-loaded blue safety switch to ensure it is making good contact when the panel is secured. The switch should deflect downward when the panel is replaced. If the contact with the panel is suspect, very gently bend the metal bracket on which the switch is mounted.
    4. 4 Replace the grill cover and the lamp door, and continue to enjoy your TV.
    jQuery('.article ol .image').each(function(i,e){ var $this = jQuery(this); $this.find('img').error(function(){ jQuery(this).remove(); $this.remove(); }); });
  • 5.Check some basics first. Make sure the sleep timer on your TV hasn't been turned on, telling your set to turn off at a certain time. If your DLP TV is acting erratically, Samsung recommends turning the set off and unplugging it for 30 minutes. After 30 minutes plug it back in and turn it back on. Unplugging the set resets it, and that may fix the problem.
  • 6 Check your power supply. Make sure your Samsung DLP is securely plugged into a working outlet. Plug the TV into a different outlet to see if the problem still exists. Make sure that a fuse hasn't blown in your house or a circuit breaker hasn't flipped.
  • 7 Replace the lamp. If your Samsung DLP is shutting off or won't turn on, a bad lamp is the most likely cause. To replace the lamp, remove the lamp cover from the back of the TV by removing the screws with a Phillips screwdriver and slide it out and away from the TV. Remove the screws on the lamp assembly and slide it out of the TV. Disconnect the old lamp and insert a new lamp into the assembly. Slide the assembly back into place and replace the screws. Do the same for the lamp cover.
  • 8 Check for signs of overheating. Samsung DLP TVs generate a sizable amount of heat. If the components inside the TV get to hot, the TV will shut itself off as a protective measure. Make sure your DLP is out 12 inches or so from the wall. Make sure that all of the vents on the set are clear of any obstructions. Allow the TV to cool down for 30 minutes before turning it back on.
  • 9 Contact Samsung. If none of the above tips help, it's time to contact Samsung, as the problem is likely something that should only be fixed by a qualified service technician. More serious problems may include a bad power supply or a bad ballast. Attempting to repair those yourself will void your warranty and may cause more serious damage to your set.


  • The safety switch exists so the user does not accidentally remove the lamp door while the TV is on. Doing so could, theoretically, result in burn or electrocution. This spring loaded switch causes the TV to shut down when the door is opened.
  • Since the TV's chasis is plastic, expansion and contraction can cause the switch to lose firm contact with the lamp door. The TV's behavior could then be such that after being on for a while (getting warm) the plastic expands and the switch loses enough contact to cause the TV to shut down. The frequency with which this phenomenon occurs is not only dependent on the internal temperature of the TV, but also the ambient temperature of the room as well as the relative tension on the switch itself. The user's perception is that the TV starts up fine, but then "randomly" turns itself off after being on for a while.
  • If you have recently moved your TV, it is very common for random shut-downs to occur. This is because the move has shifted the flimsy plastic chasis of the TV, thereby loosening the contact between the lamp door and the switch.
  • Make sure your TV is off and cool when performing this procedure.

    Hello,
    Dont worry, the problem is coincidental to you installing the Wii. You need a new lamp.
    What you are seeing is the lamp ballast/power supply attempting to start and restart your lamp. The resistance of your lamp to it's power source has increased to the point that it is shutting down, but has not blown out yet. You can find these at justlamps.com
    Good luck

    My TV turns off. As soon as I turn it back on it


    try the lamp door switch in the back of the TV, door is held on by 1 screw, after door is open there is a blue switch by the slide that protects the lamp. push the switch down and up a couple of times then put cover back on and see if tv stays on. this was my problem with this exact tv.
