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.

all 3 leds = lamp failure

if lamp is ok, it can also be the lamp driver, color wheel, or dmd board(rare)

first pull out the lamp and check that, likely your bad part, part numbers on the side of the tv, for parts.
let me know if I can provide further assistance.

Dlp replacement lamp just now installed, but TV still won't work and (3) LED lights still blinking. Any ideas ?

Be sure the lamp cover door is closed to activate the safety switch. Otherwise the set will need a ballast or possibly the color wheel is not can be defective,especially if you have heard a whining noise prior to the set failing

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
