Question about Samsung DLP HL-P5663W 56" TV

2 Answers

61" samsung DLP 3 years old. Keeps turning off by itself.

I set a small fan behind it and it works fine. I think the internal cooling fan is having problems at times. I cleaned it, but it still shuts down once in a while. It has never shut down with the fan turned on behind it. I am guessing that the internal fan needs replacing.

Get a small but powerful used computer fan and place it in the TV to replace the defective old fan.That's the best way.The factory fans in these TVs don't last.

It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

No picture, siren type noise as restarting


My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?

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.
