Question about Samsung HLP4663W 46" Rear Projection HDTV

1 Answer

I bought a Samsung HLP4663W from an individual with a known problem. He was getting 3 blinking lights & replaced the lamp & ballast to no avail. He sold it to me sure that the color wheel was the problem. When I turned the set on, it did come on for a bit, but then froze up & would not respond to the remote, I had to unplug it to turn it off. It will come on & respond to the remote at times & other times I get the 3 blinking lights.

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 starting........it can be defective,especially if you have heard a whining noise prior to the set failing

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.

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

Ballast on samsung hlp4663w


The transformer can't damage the new lamp. Faulty transformers normaly take out the driving transistors or the fusible link in the power supply, if these are good then just replace the lamp. Espacially if you know the lamp is bad (test it by swapping with the others if unsure)

Picture blinks out and in


If you haven't replaced the lamp recently, its the likely cause. If the lamp is known to be good, its possible that the ballast board (lamp driver/power supply) is defective. And, in some cases, the lamp door interlock switch may be the culprit. So make sure that the lamp door is properly aligned so the switch engages properly.

Turning off


Three blinking lights indicates a lamp problem.  This can be from A) a bad lamp, B) bad ballast C) bad Light Engine/DMD Board.  Try replacing the bulb first.  As with any lamps, it has a limited life.  If that doesn't work, you can try the ballast next.  If that doesn't work, it's time to take it in to a certified repair center for diagnostics.  Here is a page from the service manual on the three blinking lights.

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
