    was careful not to touch cause I thought of that myself & not knowing for sure, took precaution. 99% SURE I did not touch!

  • bjn7295 Jul 07, 2008

    not new lamp, old one still in-------after replacing fan#2 got indicator flashing ...lamp



    I will just go ahead & order lamp & replace, just wanted to be sure before I spend the money that that is the problem & not something else could rectify itor I did something when replacing fan#2, would like to know for future ref.



    Everyone agrees to just replace lamp! I am novice & unable to check ohms, etc.

  • bjn7295 Jul 08, 2008

    did not need lamp as all experts suggested.....only needed to put final panel on back that triggers switch for lamp......tv is working just fine, have to call & cancel lamp order now that all experts said I needed. Replaced fan #2 & the lamp is fine



    Thanks for all the costly help......I think I am the expert,not you guys, it was very simple solution no one suggested, everyone saying new lamp! That is why I kept questioning why it did not say before.....that should have been tip off for experts, no?



    Want my money back!!!!!!!!!!

It's very unlikely that the new lamp is burnt but you could use a ohmeter and check for some resistance from the lamp filaments.
If the lamp is not powering up is more likely that the lamp ballast is defective. In this type of TVs the ballast works like a FBT to provide the necessary power to the lamp.
Check this site for the ballast availability.

    I would suggest to check Youtube on how to use a multimeter, just in case you need to in the future.

    Good Luck.

If you touched the lamp with your fingers then it is burnt. You will need to replace it.

Carefully cheak the access doors for proper seating. If the lamp or the protective cover are not in the correct positions, the safety switches will prevent proper operation and show this. It is possible that the lamp is bad, but I'd double check all of the access panels first.

Keep us posted.

Over half the sets , the cause is bad(dry) joints
true the transistors and other bits may have blown, but usually the original cause is a dry joint.
The wait for fault to occur (use hair dryer to speed up process)
then spray an area, then wait 30 secs to see if any change
then another area and so on, when you get a response
spray a smaller area within the last area, and so on till part located of course when you get down to a smaller area,
you can reheat with the hair dryer, to confirm.
other wise take it to an authorized service station to have an estimate.

The "flashing lamp signal" indicates an internal error on your unit, check the manual on the model on what settings are to be changed and / or replaced.

    There's a possibility that when you replace the fan#2 the lamp got burn out, because that led indicator is a sign that the lamp is busted /defective that why you need it to be replace..

  • Mark Gil
    Mark Gil Jul 07, 2008

    Ok because base from you have said that you didn't really do any contact with the lamp when you replace the fan so I believe lets wait after you replace the lamp but I'm sure that after replacing the lamp everything will be fine..

My Samsung 50 inch DLP tv just started acting up. I have a good picture but at the bottom of the screen is a blue box that says "check the No. 1 fan". Then after about 5 minutes, the tv will shut down


I am not familiar with your Samsung 50" DLP, BUT.... The alert message implies that something is WRONG with the "No. 1 Fan." I suspect that it has QUIT WORKING altogether, and after a certain period of operation the TVs internal temperature builds up to a point where the heat becomes dangerous, either to the components, or even possibly becomes a fire hazard.

The shutting down is probably a self-protective function to prevent any more overheating which would seriously damage internal components exposed to the heat, or worse, cause a fire!!!!

Unplugging is good as it allows the system to cool down, BUT to continue use without repairing the cause of the fan failure, is dangerous!!!!

Either get your TV into a QUALIFIED REPAIR SHOP, or get a qualified PROFESSIONAL out to the TV.

IF the problem is not corrected, the TV could be irreprably damaged, or could catch on fire, neither of which is good!!!!!

Shuts off after a few minutes


This is a common problem for samsung DLP tvs and is due to the age of the lamp.

See this article for some solutions to extend the life, but in the end, you need a new tv or a new lamp.

Samsung tv turns off on its own model hls4266wx


    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.

    My samsung dlp tv model#hln617w keeps turning off. Only stays on for 2 minutes. I replaced fan #2. Thunking that was the problem.


    Why did you replace the fan was it noisey and did that cure the noise. These sets commonly have problems with color wheels-do you get motor noise at startup?

    your keeping a part that is warming up and shuts down your shutdown that protects the tv from burning up... cooler... to find this you might need a hair dryer or a can of freeze mist.
    I believe the left side is your high-voltage section.
    you can also let it warm-up without the fan .. let it shut down and feel parts with set unplugged to see what is running hot.
