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.

My samsung 42 inch hdtv is making a buzzing noise


First. The whirring or buzzing sound you hear is the Color Wheel and it needs to be replaced. Second, since I do not know when and if the original lamp has been replaced it is a good idea to replaced the lamp. The bad Color Wheel is the one causing the set to shut down.

Dlp tv problem


Is the lamp light the only one thats flashing? Does the buzzing your hearing stop or is it constant? Also when you press power off does the buzzing stop instantly or continue? Respond to this post and I will try to assist you. Is HL-R677w the correct model number also?

Samsung 42 inch projection


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.
