    This seems to make sense. I'll replace the bulb and cross my fingers. I'll check back if this doesn't work. Thanks for the patience.

Hi


Thanks for using FixYa. To start with check the lamp if that’s working fine, you can also take the lamp cover off from the back then take the lamp out and try to reset the lamp door switch and then put the lamp back in. After this if still the issue is not resolved then check the ballast which is the power source for the lamp. After doing all this if the issue is still not resolved then check the Digital/DMD Board, as you have already replaced the color wheel. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

    I have had the lamp out. I has over 13,000 hours on it which I know is like a miricle. What am I looking for when I check the ballast and the DMD board? I can reset the counter but would that make a difference?

    Nope seems to be the lamp that has gone bad and should be replaced.

  • jrader Jul 05, 2010

    Ok, maybe once it goes dark if I check the lamp then closely it should be out or dim which is causing the lack of picture? The lamp can cause the pixels to show up like that. I just hate to drop anothe $100.00 then more for more parts although I guess Ive been lucky on the lamp already.

    Lamp has 1300 hrs...usually the lamp has to be replaced after 3-5 years so it seems to be the bad lamp as the ballast is working fine coz the lamp seems to be getting the power, dont think it is the DMD board as everything else seems to be working fine.

This tv have a colors wheel design in it.The tv make loud grinding motor noises or pictures flashes or freeze and pictures turn in black&white with sound.The tv colors wheel it is dying or worn out already.Don't tries to change the tv colors wheel ur self.If u don't any mechanical skills,because the colors wheel it sit way back of the tv,must take out many mechanical parts before even can come to the tv colors wheel itself to replace it.Best to hire a tv tech. to change the colors wheel,so no problems for tv funstions for later or damages more parts on the tv set,if u install the new colors wheel in the tv wrong way.

Loud humming sound on with a purplish and pinkish screen on my 50 inch dlp samsung, 5 yrs old.


Hi,sounds like you might be experimenting a color wheel problem.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.Your part # is BP96-00250A You can find it here http://www.discount-merchant.com/Samsung-BP96-00250A-ColorWheel-Assembly-p/bp96-00250a-color-wheel.htm?Click=48173 and here's the instructions to replace it : http://www.fixyourdlp.com/guides/samsung/bp96-01579a.php Have a bless one!

50" DLP Samsung HDTV


That sounds like one of 2 things:
  1. Color wheel
  2. Light engine
Color wheel because of the losing color, but the light engine because of the picture freeze. It's very difficult to judge since I can't be there to see it. I'm leaning toward the light engine though. The only fix is to replace the DMD board, or entire light engine.

I have a problem with samsung sp 50 l7h a 50 inch dlp tv


I can see you have a Samsung TV, well the issue seems to be your ballast which doesn't have enough voltage to keep on with your lamp. This is why you keep losing the picture every certain amount of minutes. The thing with Samsung Tv's is that they have issues with the ballast and the color wheel, they tend to go bad pretty fast.

I have a Samsung 50 inch DLP - I heard a pop and the picture immediately disappeared. The 3 lights were flashing on the front which according to the book said it needed a new lamp installed. I ordered it,...


Sounds like the color wheel may have also gone bad. I recently saw a 56" Samsung where the bulb and color wheel went at the same time. The color wheel could produce a crying noise while trying to spin up.
