Question about Samsung HLP4663W 46" Rear Projection HDTV

2 Answers

Samsung HLP 4663

I also have had a problme with the Samsung. When I turn the set on, the picture stays black, the sound comes on, and first the "lamp" light flashes on and off. This progresses to all three - "lamp, Standby, and Timer" flashing. I have tried to replace the lamp with no change. I then purchased a new ballst which also was easy to change out. I still have the same problem. I still don't feel that I am any closer to having a working TV. HELP!

    I am having a problem with my 4663. When I power on the TV, the fan comes on, but I get no picture. I have to power on the TV several times to finally get it to show a picture (takes 20 or more minutes). I have noticed a blue colored electrical short under the projection lamp case on the circuit board, and you can hear the electric arcing when I see the glow. Not a big short where it could melt something, but one nonetheless. The short will last about 2 to 3 seconds and then go away. Any assistance would be appreciated.

    I have the same problem in my Samsung HLP 4663, it is nightmare, I told myself that never buy any Samsung TV again.

    I changed the bulb. It worked fine then shut off. I get all different combos of flashing lights. I took the panel off and put a fan back there. It work fine for about 6 hours. The next it powered up fine but only worked for 10 minutes.



    I was told that if the picture comes on nice and bright for merely a fews seconds it's not the lamp or ballast.



    My color wheel is not making noise and the picture seems to be fine.



    When I go through the steps to get data on usage it never works.



    1. menu

    2. 1-8-2

    3. power



    this will not work



    I'm getting ready to throw a brick right through this mother scratcher

    I have the same problem on my HLP5063W and I have not replaced anything yet. Did anyone ever correct this type issue?



    Sound, no picture, lamp LED blinks for 30 sec and then TV reboots. This happens 3 times and then all three LEDs blink, which apparently indicate a defective lamp. However, I'm not so convinced. Prior to last night, the lamp was working intermittently. A couple days ago, I removed the lamp housing and examined the lamp....it looks fine.

    I have the exact same problem with my Samsung...by the way this is the second issue in 3 years. I had to have the color wheel replaced about 18 months ago. I did all the usual stuff like change the bulb and clean the fan, but that did not fix the problem. I bought the extended warranty so I called and they came out. They could not fix the problem on site (even though I pay for that) and had to take it to their shop. Their diagnosis is that I need a new light engine. The warranty company has to approve such a repair and I am told that will take about a week and then another week to get the part and make the repair....so about 18 days from their original visit to my house to get my working TV back. This is the last Samsung product that I will buy. The picture is GREAT when the TV works but it has been a major pain since I bought it. I am on my third bulb, replaced the color wheel, and now the light engine...never again with DLP and especially Samsung DLP.

    I have exactly the same problem for about over a year, now my TV HL-P4663W died completely. No more SamSung. SamSung should repair for all buyers, this is not one or two TV, it looks like this is a serious defected model from manufacture. My brother bought a Sony TV, the color went wrong, Sony repair for FREE! Why don't anybody submits an request, with everybody signs on this, to SamSung to see what can they do for us?

  • Anonymous Jan 20, 2009

    I have the HL-P4663W and replaced the color wheel. I removed the jumper and it worded great with a good picture. Three days later it shuts off...three lights blinking and now it will not ture on. I replaced the lamp, still no good....



    Can anybody help?

Skippy is right, you should check the color wheel. There are only two moving parts in the set and the color wheel is one of them. If you listen closely to the TV you may hear a high pitched whirr or whine. If so, you've got a bad color wheel motor. If you are mechanically inclined, take the back off and remove the lamp vent. Take off the screws and cables holding the optical block tray and slide the tray out. The lamp points directly at the color wheel. There is a metal heat sink held in place by two silver screws over the compartment infront of the lamp. Using latex gloves, remove those and the whole color wheel assembly will come out. Of course this process isn't as simple as I've stated it but with some common sense you'll be fine. When replacing the wheel pay attention to the model number. Some of these sets use a bearing setup and others an air cushion one. Make sure you order the right part. If you do order the wrong one, not all is lost, you can (with a jumper) modify it to work. Make sure your gloves are clean and re-install the color wheel, and reverse your dismantle. Good luck!

    by the way, I see a lot of broken Samsungs, don't feel singled out. Of all the tv's I've repaired over the years, samsung seems to be the brand I constantly have in my shop. But it is also the most service friendly. They can be fixed easily. Keep in mind that almost all brands of TV's use philips and samsung parts, boards, etc. So changing brands may not be your ultimate solution. Sony on the other hand is the brand I see the least. But when they die, they are DEAD. Fixing sony is often a nightmare. Moral of the story, 6 of one half dozen of the other. Pick your battle wisely.

If you heard recently a high pitched sound or fan like sound it may be the color wheel--if it fails the set will detect that and shut set off.

If lamp comes on even for a few seconds it likely is good--ballast which drives lamp is possible but rare.

Burned out lamp?


First. Turn on the set and see if the Lamp Illuminates, If so then you have a bad Color Wheel. If the Lamp does not light up, you have a bad lamp.
Take out the lamp and look to the center of the lamp. If you see broken glass inside you have a bad lamp.

Chances are that the Interlock Safety Switch is not properly set. Remove the Lamp Door and then reinstall the door and tighten the screw. This will reset the Switch. If that does not fix the problem make sure that the Lamp is correctly seated. Beyond that you will need a trained samsung tech troubleshoot the set because it can be a bad Lamp Ballast,DMD bd,Main bd,Color Wheel. Also make sure you have the correct lamp. There is a Lamp Code sticker on the left side of the set. Match the code from the tv to the new lamp you purchased.

Samsung HLN5065W Lamp won't stay on.


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.

T.v. will not turn on. flahes "lamp" then no picture!


This will have to be narrowed down to a specific problem. I would try the easiest things first. First check the lamp. Is it bad or just starting to go bad or does it just need to be reseated with the ballast? If the ballast flickers when turning on your TV, then you will know it is the lamp that is not working or the ballast may need to be replaced. If that is not the problem next check to see if the color wheel is spinning or broken. If broken, it will need to be replaced. If not spinning it is the DMD board that is bad. The color wheel is plugged into the DMD board. If the DMD board is good it will spin the color wheel, that is what will start your lamp. When you lamp starts, you have your picture.

No picture and no sound


simply unplugging the TV and turning it back on if started to work.
if it doesn't then the Trying a new lamp first is reccommended.
After all, you will need another lamp eventually.

model HLM507W as two different lamp replacement part. the LAMP for my TV was BP960224A. the replacement lamp listed on the Samsung site is BP960224C which was replaced by BP960224J. the difference according to my supplier is that A part has a brown power coupling and the J part has a black power coupling. hope this helps someone in the future. The couplings are different and a black LAMP coupling will not fit a brown TV coupling.

Replacement is simple, getting the right bulb is tougher. Make sure the TV is unplugged and the lamp has cooled. Looking at the TV from the back there is a lamp cover on the lower right. Remove the single screw, remove the door. There are two screws holding the lamp in, loosen these. Then flip the black plastic handle up at the bottom of the lamp assembly and pull the lamp assembly out.

Note the brand of the buld and the color of the connector (black or brown) and then call to order your parts from Samsung's parts reseller

With set off...mute + 1 + 8 + 2 + power.
Arrow down to "Options" push enter.
Lamp reset and lamp hours should be in there.
Power off 2 minutes or until fan kicks off to exit.

Unplug the set, pull out the lamp module (not all the way - leave it on the track) and push it back in.

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.
