    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.

    If these dots are only seen when the picture is on I would look for the Optical Block to be causing it. Are the dots in the same place each time you turn it on?

    I put a lamp in to my Samsung HLS4266WX/XAA, but when I actually took it apart for the Bulb replacement which I have done twice now. I found where that switch is, that gets pressed when you have the back cover to the bulb screwed in was hanging, and I can get the new bulb and my replacement bulb to work for about 15 secs, and at one point it was working really good. Can anyone help me with this problem, cause Im getting frustrated. It seems like a simple fix,but its almost like the bulb I ordered is not as good as my other replacement bulb.Its from MWAVE.com, anyone heard anything about this company? Please help if you can, id really appreciate it.

    In all likelihood then the ballast is failing, this is very easy to replace just a little board attached to the lamp by a couple of wires, just when you remove lower bottom have a look at the lamp wires and you wont go far wrong it's available here


    The part is in that link highlighted in my last post just click on it and it will take you to the supplier, if you cant fit it yourself a technician shouldnt charge more than $100 for the housecall and fitting unfortunately there are a lot that want $150 just to turn up so if you could get someone whos practical this is very easy to do.

    Let me know,if needed further assistance.

    Hope i helped you.

    Thanks for using ' Fixya ' and have a nice day!!

    I can't explain the timing of your problem and why it showed up after lamp replacement, but Samsung color wheel failures are usually associated with a rather loud hum. I would removed the back, jumper the lamp door switch and try to determine exactly where the hum is originating from. I think you'll find the color wheel is the culprit.

    You need to replace the dmd board.In some cases it is more cost effective to replace the entire optical engine which includes the dmd board,lamp,ballast and color wheel for about the same amount of money and is easier to install.
