Question about Samsung HLP4663W 46" Rear Projection HDTV

1 Answer

Sumsung HLP 4663W

I have a 46 inch dlp model # hlp4663w, the 3 lights were blinking in front of tv and that says that the lamp is bad. The 3 lights are blinking together and will just keep blinking all night. So i changed the lamp but now when i turn the tv on the picture will only be there for about 3 mins and then it goes black but i still hear sound. The problem with that now is that i can't turn tv off(i press power on tv and remote and won't go off) The only way i can turn it off is by unplugging the tv. When i plug it back in it does same thing(picture goes black but i hear sound) the old lamp was still producing a picture so i put that lamp back in but still was going black and i had sound. And i still had to pull the plug to get tv off. I need some help to fix the problem

    I have almost the exact same problem but I don't get sound. Other than that everything is the same.

    My issue is similar! But the fan is cycling off & on at the same time. I know nothing about this tv but any info would be greatly appreciated.

    I have also just replaced the bulb and continue to not get a picture and can't shut it off. I am also getting a loud hum.

    I'm having the same problem. I just changed the lamp and ballast since that's what Samsung said was probably wrong with it. After I unplug the TV for 20 minutes or so, I turn the TV back on and it works fine for aabout 15 minutes then shuts off again. Sometimes I can't turn it off. I don't think it's the color wheel since I do get a picture even though it's for a short period. I'm running out of options. I've had this TV for 3.5 years. I still get the three lights that blink on the power switch as well. Any advice.

    I have the same problem after changing the color wheel. No lamp, TV doesnt start, Lamplite on, TV doesnt shut off.
    Samsung doe not offer technical help and J&J tell you they are parts ditributors, not technical.
    In desperation I re-installed the old color wheel to see if the set went on .
    Everything went I as it is supposed to; therefore the problem lies in the colore wheel.
    P.S. I called Samsung again today they recommended an authorized service center who pollitly put the cost at $500.00 to fix the problem.

Samsung HLP 4663w dlp-hdtv replaced lamp and ballast, still not working. lamp/standbytemp and timer all flashing. i get no clicking on ballast, upon power up all i hear is low fan or vibration sound which...

If the capacitor on the ballast was puffed up or blown up you have to replace the lamp, ballast & SMPS at the same time. But if the ballast is not trying to fire the lamp it sounds like the color wheel is not coming up to speed. If this is the case, the set will not turn on.

I have a hlp 4663w that will not turn on checked the bulb it good. three lights blink that it .what is the prob

First. Lamps can look ok in the center and still be bad. Install a new lamp since I do not know when you replaced the lamp or if at all. Turn on the set and at the same time look through the Lamp Door vent slots to see if the lamp Illuminates. If so your lamp is ok and the Color Wheel is bad.

Just changed the lamp in my samsung 4663w. lamp light blinks a while then all three blink. sound but no picture

hi, leaves only 3 options
1. color wheel not coming up to 6000 rpm`s
2. no ballast strike to lamp
3. lamp door safety switch in wrong position when door was re-attatched.
highly unlikely but not impossible u got a defective lamp, did your old lamp still come on? if so put it back in, if it lights up new lamp is bad, my money is on the color wheel if you installed lamp door correctly, gl, video-tek

Samsung HLP 4663W DLP TV

If you have already replaced the lamp and ballast, to no avail, then it is time to take it in to a certified repair center.  Most will charge a nominal diagnostic fee.  My 61" did the same thing and it turned out to be the Light Engine (of which the DMD Board is a part).
If the problem were the color wheel, the lamp would come on for a bit until the color wheel sync couldn't be achieved and then it would turn off.  The all-3-flashing-lights problem is the lamp.  Here is a page from the service manual on the 3 blinking lights problem.  
The Light Engine controls the ballast via a separate signal than the 320 Volts.  The voltage reading means that the Power Board is working properly.

Replaced lamp & color wheel, no picture

Check your old lamp. Do you remember what its condition was like. If the tube inside the lamp was shattered into a thousand pieces that is a sign of ballast problems and that is where you should start to look. After all the ballast is what runs your lamp.

Tv turns itself off after a few moments of clear viewing

HLP, HCN HL-S The Start-up Problem or/and
3 LEDs in the front blinking.

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

good luck
