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

1 Answer

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 off. The sound reminded me of Chewbacca from the Star Wars movies. Now it just shuts off without first making any noise. The picture and sound are fine until shutoff.

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.

I replaced the color wheel in my HLN5065W DLP tv now I dont even get a picture. After 3 times of it restarting itself I get 3 flashing lights on the front of the TV.


THIS IS JUST A SUGGESTION, IF I am right give me a very helpful vote here and a note, check the ribbon cable----color wheel has two cables--one regular and one orange--look at contacts on orange one--they should face the back of the light engine--it is very possible to put the cable in backwards--common issue.

Samsung dlp hdtv turns itself off


I worked on one of these for a few weeks. if you dont mind a little inconvenience you can remove the back lower cover and defeat the bulb door switch and it will run. the last one i had like this we could not find the problem even with samsung tech support. changed many parts in the mean time. its heat related but the lamp heat sensor in our case was not the problem.

Replaced lamp still not working


Power issues (Tv True True (``````````` (``````````` 0 95250 95250 clip_image002.gif not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung True True (``````````` (``````````` 0 95250 95250 clip_image002.gif is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.
