Samsung DLP HLM437W won't turn on

I have changed the color wheel in my Samsung HLM437W and it worked fine. The next time I turned it on the lamp light came on and the tv wouldn't turn on. After it seemed to try to re-boot itself a few times, it flashes all three lights as if the lamp is bad. I replaced the lamp and now it just keeps doing the same thing with the lights. No sound, no picture. It just blinks the lamp light and tries to restart itself then eventually all three lights stay on in the front. Please help; this is getting expensive!
Thanks...

My advice is that if the project is getting expensive kindly invest in a new tv. i am nt familiar with that set but you are having a micro processor problem replace it and your tv will work fine as it was before good luck.

I have a 50 inch DLP samsung and it wont power on after making a lot of noise (I replaced the lamp) worked fine for a few days now the red light and the right side green light is blinking. any sugge


The answers above are correct. It's either the lamp or the color wheel. Testing the lamp is pretty straight forward. Use an Ohm meter to see if the it's filament has continuity. It's unlikely that a good color wheel would fail immediately after changing the lamp. Look to see if some wiring is out of place and rubbing the wheel causing the noise you described. A jammed but otherwise good color wheel would cause the TV to shut down and display an error code.

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.

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

Samsung DLP will not turn on


If your having the "3 light" problem it could be an indication of a bad lamp however if there is a buzzing or a grinding sound it could be one of two moving parts. The color wheel or the cooling fan. I would go the cheaper route and replace the color wheel first. The thing is the lamp will not turn on if there is a problem with one of the other two parts. TRUST me ... I've replaced all three parts just to find out it was only the cooling fan. (at least I have another lamp handy when the new one goes out). The motor on the cooling fan is too small for such a big fan so I would definately try it first. It's a big problem with the DLP tvs. Hope this helps.

Samsung dlp


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?
