Question about Samsung DLP HL-P4663W 46" Rear Projection HDTV-Ready Television

2 Answers

Very noisy when turned on, then shuts down, Samsung 61 inch

It sounds like a fan running then binding up, but a visual of both fans shows no problem. Even replaced the small one! Just Replaced the bulb, because of previous bad bulb indicators on the front ,but the racket continues until the set shuts itself down in 30 seconds or so. Thanks in advance for any suggestions. I have the same problem but my model is the hlp5063w , I have replaced the bulb once. My tv didn't always shut down, the noise would usually go away after 20 min. or so. I think you are correct on the color wheel being the problem, but the lamp light on the front is flashing again and the set won't turn on so do you think I did another lamp assy. in again.

Need help, what can be wrong at this point. Have tried several test and replaced the color wheel, but nothing was or is making any noise ??


I think you have lost the fan. Check the installation and make sure the fan switch is activated. You must have a fan going or the bulb will actually burnout soon that is why the fail safe circits are shutting it down; to keep the lamp from burning up. Got to get the fan going.

Ceiling fan runs slow on highest setting. Or not a all on lower settings. Motor hums so it is try ing to work.


Sounds like something is binding. If you have full voltage on the fan and you can't find the source of what is binding, you will have to replace it.

It could be one of the fans has stop working or it could be just the bulb needs to be replaced. Does the set even come up.(show a picture)? If not its more than likely the bulb. Hope this helps.

Infocus x2...the bulb melts the small square lens even w/ fan on


there is more than one fan inside. one of them may not be working. also, if there is excessive dust inside, the heat won't leave. blow out all of the dust with canned air. if one of the fans are running slow, replace it. lastly, do not use an aftermarket lamp. get a good one from the comapny.

Infocus x2, the bulb melts the small square lens even w/ fan on


either the ballast is bad and is sending too much current to the lamp, the lamps are a cheap knockoff, the thermal fuse is altered, and/or one of the fans aren't working.

Fan noise loud, bulb burst. Replaced with new bulb. Noise even louder! Unit shuts itself off.


the bulb may have burst from overheating from a fan not working to cool it down. and it can be replaced. it does take, however, a while to replace it because you have to take half of it apart. but make sure it's the fan first. take the lamp door off and remove the lamp. use something small and thin to push in the switch that the lamp door usually activates. turn the projector on and see if the lamp fan and the colorwheel (the multicolor glass disk) are spinning. if the fan spins, the noise may be from the colorwheel motor going bad. the fan can be purchased through an infocus authorized service center. check the website for the closest one. but the colorwheel for the x1 cannot be purchased seperately from the optical engine, and that costs a fortune. but here is the part number for the 80mm fan- 526-0152-00.
