Question about Samsung HCM4215W 42" Rear Projection Television

1 Answer

I have a samsung hlp5063wx. I just replaced the color wheel. It worked fine for two days. Then no picture or sound. After I turn the tv on the lamp LED on the front flashes. Then it goes thru its cycles. It makes a bunch of clicks then turns itself off. Then all three LED lights flash. Lamp, timer, and standby. I am getting 323 DC volts to the ballast board. But nothing coming out at the lamp socket. Is the dmd board not turning on the ballast or is the ballast bad or are both gone? Thanks in advance for the help.

    No i don't hear the wheel spin up. I checked the bulb for continuity but didnt have any on the bulb. What are your thoughts. Maybe the color wheel went bad. Thanks again.

    Do you hear the color wheel spin up? The lamp will not lite without a spin up. Odd thing... more than once I have changed a lamp or a color wheel and days later, the other one goes.

If the color wheel doesn't spin, the lamp will not fire. The lamp has a gap in it, it will read open. Pull the rear cover off trip the door switch and look close and listen. Double check that the color wheel does not spin up (turn on, then wait 5 secounds or so.. pull the power cord and listen for it to stop.. best method). Also, watch the lamp driver.. there is a condensor coil on there that will lite up when it is sending the ignition pulse to the lamp... do you see it? If so, it's the lamp.

the lamp led will light when the color wheel is defective. If the noise you hear is a buzzing or screeching the color wheel is the most likely cause.

My Samsung 50" DLP HDTV keeps humming when the DLP lamp comes on.


Hi, you have one of two problems, either the color wheel is going or one of the cooling fans are going, the color wheels are a very common problem in samsung dlp`s, sorry I can`t nail it to a specific part but I`d bet it`s the color wheel as they are notorious for failing in samsungs, video-tek

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.

Sound but no picture


there are several things that need to take place for the lamp to turn on. first the color wheel needs to turn on ( if you can hear a whinning noise then this is fine) next the tv will send a signal to the lamp ballast to turn on, and the ballast needs the 130v dc supply from the power board ( simoly remove the lamp and reinstall the lamp door, turn tv on, and if you hear an arcing noise from the ballast you know this is fine too. the board that controls all of this is the dmd board. so if the color wheel works, ballast starts then i would replace the dmd board....

Here is a site for ColorWheel replacement, which is what you need to do if you hear that screeching or fan running noise coming from your TV. Sometimes the wheel just explodes which gives you no picture.

HLS4266W 43" dlp. In less than 1 yr whining grew worse, but did know what it was. Year passed with warranty and lamp went out. Replaced lamp. Worked for 3.5 hrs. Turned on next day and did not work. Got another lamp, but did not work. Figured out might be color wheel. Replaced it too. TV started up. Watched that night. Turned on next day, heard loud pop. Lamp never came on. Withdrew and reinstalled lamp a couple times to see if that worked. Did not. Currently, with new lamp and color wheel installed, lamp light blinks, but no lamp comes on. What now?
