Question about Samsung HLN5065W 50" Rear Projection HDTV-Ready Television

1 Answer

Samsung HLN5065W Lamp won't stay on.

My set will only stay on for a couple of minutes, then the lamp turns off. If you try to turn it on it cycles on and off with sound only.The lamp will not turn on unless the set has been off for 30 min. Installed new lamp and does the same thing.

    All of the fans are running, and all three lights come on in the front when it initially shuts off. Blew out all the dust when it first occurred.

Do you get any flashing lights?  Such as Lamp or Temp?  A common problem with these is the light not coming on.  Sounds like a temperature issue.  When you turn the TV on when it is cool, pull it forward and check the rear on the left to see if you can see the fan turning where the lamp is.
The light system is pretty straight forward:  Power Board -> Ballast -> Lamp.  It is controlled by the DLP Board, though.  Since it is powering up, it sounds like the Power Board and Ballast are okay.  The ballast is used to kick start the lamp on (similar to flourescent lights) but not during normal operation.

Samsung HLN5065W replaced the lamp. Tv wont stay on.


When your TV turns off without any reason, there are a number of possible causes. The problem could be a loose connection, a sleep timer that's been activated accidentally, or even a buildup of dust on the circuit board that causes overheating.

To help you better determine what the problem and solution might be, follow the simple troubleshooting steps in the article TV turns off. I hope this helps!

My Samsung HLN5065W turns itself off after about 15 minutes, and all three lights on the front panel flash. The first couple of times this happened, there was a loud muffled sound before it shut itself...


This is a DLP projection that has a ballast and color wheel along with a lamp. The three flashing lights on the front are a diagnostic code. The exact meaning is listed in the owner's manual under troubleshooting. I don't have the manual for your model with me at the moment, so I can't look it up. Since the unit works OK for a while, it suggests that a component is failing under heat stress. This is often the ballast. The ballast is the part that provides the power for the lamp similar to the ballast in a flourescent light. Check the manual for the code and post it here. Also, because your model uses 2 different ballast/lamp combinations, you will need to get the lamp number off of the lamp. Please post that here too.

In the meantime, check the rear area for any obstruction in the air flow. There should be a fan in the rear that needs to be clear of debris and can turn freely. With the set unplugged, try turning hte fan by hand. It should turn easily and continue on its own slowing down to a stop. If it stops suddenly, the fan may be defective and not moving enough air to keep the lamp cool.

Keep us posted.

Samsung dlp


HLS4266W 43" dlp. In less than 1 yr whining grew worse, but did know what it was. Year passed with warranty and lamp went out. Replaced lamp. Worked for 3.5 hrs. Turned on next day and did not work. Got another lamp, but did not work. Figured out might be color wheel. Replaced it too. TV started up. Watched that night. Turned on next day, heard loud pop. Lamp never came on. Withdrew and reinstalled lamp a couple times to see if that worked. Did not. Currently, with new lamp and color wheel installed, lamp light blinks, but no lamp comes on. What now?
