Samsung HLM5065W DLP shuts itself off for no apparent reason

I have a Samsung HLM5065W DLP that shuts itself off for no apparent reason. I let the TV sit for a few minutes and it turns on again. I just replaced the lamp a few weeks ago, but the shutoff continues so I can guess that this has nothing to do with the lamp. Any thoughts?

Same problem. Went through the gambit, lamp, color wheel then they said it was the board for $600. Can get a new tv for that. Sent board to company who claims to fix it for $40. Got board back and now nothing works. Filled a complaint with attorney general after hearing others did so and samsung fixed it. Waiting on last effort.

Try replacing the ballast next. Its the small circuit board directly underneath the lamp housing. You can access it through the lamp door. If the ballast is overheating or has a leaking capacitor, the tv won't stay lit for more than a minute or two.

SOURCE: Samsung DLP 62 inch turns off by itself after being switched on

I had the same issue but instead of shorting out the sensor, I removed the bulb assembly, cleaned the interior of the assembly and TV the best that I could with a vaccum and small paint brush. Once cleaned, I reinstalled the bulb assembly and the TV has worked for the last eight months with no problem.

Had similar problem. Thought it was the lamp. Examined old lamp but it appeared to be good. Ordered a new one anyway. Changed the lamp but the TV screen would not come on. It would make the usual noise as it was going to come on normally but it would cycle 3 times & then turn off. The LED lights in the front panel would indicate a defective lamp. Then read about the ballast. Changed the ballast & still same problem. Tried starting the TV without the lamp installed & noticed that the color wheel did not spin. Removed old color wheel & discovered it was broken. This appears to be the cause of all of my problems. I wish I new earlier of the test-turn on the TV without the lamp being installed & check to see if the color wheel is spinning. Would have save money on the lamp & ballast.

I have had this Samsung DLP HL-P 4663W for about 3 years now.


    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.

    The lamp ballast or Color wheel might be the problem. We have experienced both issues with the tv shutting down. Also check the hours on your lamp as it might be getting old.

    Tv shuts itself off


    Look for the computer processor inside the TV. It needs to be cleaned. A can of compressed air will work. The processor is overheating and causing the tv to shut off. Look for the small fan that is supposed to keep the processor cool then remove the dust.

    Good luck!

    Flashing


    I am currently having the same problem. It started they way you are discribing, but now the TV will do that after the TV has been on for 20min and then will shut off within 30min. Then all the lights up front flash. I have replaced the bulb and that was not the problem. I also NEED HELP! Occasionally the picture on my TV will be inverted and sort of "dance" back and forth on the screen.
