We bought this tv (Samsung DLP Hln617W) end of 2004 and had to replace the bulb last year. Now a couple days ago i'm watching and hear a pop and then the picture goes out, so i turned it off.
Next day we turn it on and we have picture, but only in black and white (not a negative looking type of picture) just no color on the picture or any of the menu or control panels that are brought up on the screen.
Any idea what the problem might be? i've read this tv has a color wheel. Could that be it? Unfortunately, we are not under warranty.
Thanks for your time - Colleen

Re: Our Color TV is now Black & White
It could be the color wheel and in fact probably is. I've seen them shatter which would explain the noise. They are glass and spinn at 9000 rpm. An involved repair though definatley a job for a pro. It could be worse, probably a few hundred will do it. Was the TV begining to be a little loud before the failure? Could be a sign, i've seen many noisy color wheels.

Yes,the problem is the colors wheel it dead.That one of the cause by the colors wheel,other are alots of squiling noises and making very loud buzzing sound.The cooling fan that u think is overheating,does it stop sometimes,when the tv is still on?Yes,than replaced it also,no than it still ok.Just hire the tv repairman,the parts he'll take care of it,don't order the parts,u might get the wrong parts or different sizes,that will not fit in ur tv.
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.
Samsung is notorious for having bad color wheels in their DLPs. Well lets just say they are like toasters, they only last a certain amount of time. If the color wheel isn't spinning or is broken, the set will power down almost immediately after you hit the button, you may not even hear the entire fire up jingle. Check the wheel, if you can see the bulb light up for that split second. Actually, check it whether the bulb lights up or not.
I am actually having the same problem. I just reciently installed a new bulb and messing around in the service menus, and ended up with the same problem. I found that if if in the same menu the aging pattern was in, I think it was the last menu, and click on the EW RESET, let the TV reset and that should fix your problem.
all 3 lights blinking means lamp has a fault the service manual says replace the lamp. If you need the service training manual for that model let me know and I will post the link as the training manual has excellent trouble shooting breakdowns for that model DLP
