Samsung hln617w dlp tv won't turn on. Red temp


Had similar problem. Thought it was the lamp. Examined old lamp but it appeared to be good. Ordered a new one anyway. Changed the lamp but the TV screen would not come on. It would make the usual noise as it was going to come on normally but it would cycle 3 times & then turn off. The LED lights in the front panel would indicate a defective lamp. Then read about the ballast. Changed the ballast & still same problem. Tried starting the TV without the lamp installed & noticed that the color wheel did not spin. Removed old color wheel & discovered it was broken. This appears to be the cause of all of my problems. I wish I new earlier of the test-turn on the TV without the lamp being installed & check to see if the color wheel is spinning. Would have save money on the lamp & ballast.

It keeps shutting off. Anywhere from 2 or 3 times


Could be several things. First replace lamp.Remove lamp door and put it back on making sure tab on door presses door switch downward when closed. Can you heard spinning noise from front. Bad color wheel will cause shutdown. Look at big cap on ballast . iff swollen replace lamp, ballast and power board. Is voltage to ballast from power board below 350 volts if so replace power board. hope this helps. Most common are lamp and door switch in up position rather than downward .

My Samsung DLP model HL-P6163W keeps turning on and off and now lights are flashing. We replaced the color wheel last year and about two years ago the lamp.


could still be the lamp but it could also be the Ballast for the lamp has failed. I've replaced a lot of Ballasts on DLP machines.

My Samsung DLP hln567w tv has NO picture on all


If the Lamp ignites and stays lit, but screen is completely black, not even the on screen display, then it is likely a bad DMD board.

If the lamp ignites and then turns off after a couple seconds then it is likely the color wheel is seized.

If the lamp never fires, but the TV clicks a bunch of times, then it could be a bad Ballast or the Lamp itself.

My samsung DLP hls5687wx xaa shuts off by itself. How do I fix it?


The lamp ballast or Color wheel might be the problem. We have experienced both issues with the tv shutting down. Also check the hours on your lamp as it might be getting old.

Verify color wheel is reconnected, color wheel needs to get up to speed before lamp strikes

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.

Sounds like you've already gotten into the repairs. The three major things that fail on DLP are the bulb, the ballast and the color wheel. If your bulb is new and you aren't getting anywhere, replace the ballast, if that is still a no go, then move on to the color wheel. If replacing those three doesn't fix the problem, you will have to whip out the multimeter and start looking for problems on the PSB. You can get a ballast on ebay for about $100. Start there. The color wheel should be very freely moving. If something is grinding and hindering the movement at all, you need to replace it. That grinding may not seem like much but it is likely enough to keep the wheel from spinning at proper speeds. The sensor then kicks in and tells the brain that there is a problem and the brain keeps the ballast from firing the lamp.
Good luck.

Power issues (Tv 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 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.
