Question about Samsung DLP HL-P5663W 56" TV

1 Answer

Samsung HL-S5087W shuts off.

I believe that the problem is that the safety switch next to the lamp door is defective. I need part number and cost for this part.

Eb

P.S.
The other day the TV was shutting off every 5 minutes. I opened the back door to check for dust and or fan operating. After replacing the door the TV worked continuously for many hours. I think that contacts on the switch get corroded and opening the lamp door will clean the contacts on the switch.

I almost sent my TV to the shop a year ago with the same problem. After opening the lamp door and checking that it was properly set, the TV decided to work just fine for over a year.

Samsung memo correctly shut the light door


These sets where the door is to gain access to the lamp there is a lever--it is a safety switch that may either not be engaged or bad--it can be checked for good bad with a resistance check and sometimes the switch gets moved enough for it to shift out of position--if rear door then tape it in the closed position to see if not engaged by the door.

Called a lamp door.

I have a Samsung DLP 50" TV (HL-R4667W) that has been nothing but trouble. The bulb has to be replaced about every 6 mos or the set turns itself off. I believe there is some other problem other that the...


If the color wheel is the problem you can generally hear a high pitch whine coming from the TV. If it is seized the lamp will ignite for a few seconds and then shut off.

The ballast is only used to ignite the lamp, it shouldn't cause the TV to turn off once it is on.


Since the TV shuts off after it is on I recommend the following:

1st - The lamp cover has a safety switch. if the lamp cover is not pressing on the switch, the TV will turn off after random periods of time.

2nd - The other thing to check is the fan for the Lamp. If the fan is seized or spinning slowly, the lamp will heat up and trip the thermal protection switch. Once that happens the lamp is super hot and could rupture while cooling down.

My 56 inch Samsung DLP keeps shutting off. I have


Once before I had this same problem and FixYa gave me the solution. When you replace the lamp door, there is a switch inside so be sure the door is put in at an angle so to hold the switch up. It solved my problem after numerous repairmen missed it.

My 56 inch hi-def projection samsung tv turns off automatically


    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.

    Samsung HL-S5087W DLP picture is distorted


    If the picture is distorted it probably needs reapir. I recommend doing a little research to find a reputable reapir shop. You can ask where you bought it or where they sell TV's. If you get two answers the same it might be worth talking to them for pricing.

    Personally, I believe if we went back to actually manufacturing things in this country and stopped importing everything, a lot of these problems would STOP!

    Mine did that when the color wheel didn't spin up...just give it a whack where you installed the light & the wheel should spin up. I had to replace my color wheel as the bearing was shot & was buzzing all the time. The light won't come on if the wheel doesn't spin up first.
