Sounds like a problem with source recognition. Could have a problem with input coming into the tv such as cable connection problem, loose wires, etc. Try reseting the cable box and removing and reinstalling all of the cables in the back and the cable box.

Try checking the on/off button or standby button. Does it flash multiple times? Does it show any other words besides on/off? The trouble code is usually identified by the number of times the on/off or standby button flashes. These codes can be found at Samsung's trouble shooting website.

The lamp may just be bad. Check with Samsungs solution center and trouble shooting first. Most likely needs a new lamp though and can be purchased through Samsung on-line and delivered to your door. I had the same problem and the flashing light on the standby light is actually a code for the problem. Sometimes you count the number of flashes to identify problem code.

hello
This looks like a colorwheel symptom, does the sound is like a mechanical sound? high pitch sound? winding, whirling or screeching noise ? well if this is the color wheel, what i think it is, it seems that it is not working properly when this happens the DMD board recognizes that it is not spinning at the correct RPM and turns off the Tv for sercurity reasons, so if you want to replace this yourself what i recommend you to do is to open the back of the Tv and search for the colorwheel it can have missing parts or it could be shattered or it could not spin correcty, hope this info. can help you.

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.

you have the same problem I have. The problem is fixed by changing the new light bulb. The problem appears again after 1500 hours of use. You can keep buying new light bulbs or avoid it by not buying another Samsung TV.

After color wheel replacement, there is adjustment requires, it calls Index Delay Adjustment. I would recommend to have service manual cop in hand as procedure is written in service manual, however, below is brief procedure about index delay adjustment to correct color phase/ color wheel timing to have correct colors.

1. Turn off the power to put the unit into the STAND-BY mode.
2. In order to enter the Service Mode, Press "Mute" → "1" → "8" → "2" → "POWER" buttons on the Remote Control.
3. Select "Service" on the first display of the Service mode menu.
4. Press the ▲ ▼ (Up or Down) button to move to INDEX DELAY, then press ENTER to select.
5. The INDEX DELAY setup screen (with a red bar at the bottom of the screen) will be displayed.
6. Press the ◀▶ (Left of Right) buttons to adjust. Check the red color at the bottom of the screen at its minimum and maximum
values of changing from red to magenta, then adjust to the mean value.

Hope these info will help you.
Let me know if you have additional question.
Thanks.

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. I

Thank you, please keep up posted about white dots issue in your tv, I think cause would be defective DMD Chip.

Sounds like you need to pull the jumper from the DMD board.
That is the board the color wheel wires plug in to.
On the back side of the board (facing back of the tv) , the side with the heatsink on it, there will be a little window or square opening in the shield. There will be a jumper there you need to pull with some needle nose pliers (if there is no jumper, then you will need to add one - it uses a standard computer hard-drive type jumper)
basically, these use two types of colorwheels, and the jumper tells it which type you have in there
if you have the jumper issue, you will see different colors in your picture, but they will be all wrong, like the blues will be red, etc.. if the pic is all brown, something else may be at fault.
sometimes when you replace the colorwheel, you may need to adjust some data in the service menu, let me know if the jumper doesn't fix, and we can address this later, as it can backfire and shouldn't be messed with unless necessary.
best of luck, let me know if you require further assistance

Hi:
This is and indication of a bad color wheel assembly, you can replace the color wheel yourself, there are lots of Youtubes videos on how to do this.
