Re: samsung hln617w non power up
Most of the time when these sets won't turn off it's caused by the DMD but check the color wheel connectors first, especially the flat ribbon cable. Make sure it's in the connector in the correct direction, only has contacts on one side and make sure the ribbon is not torn.

No. This is a DLP TV. It gets it's color by a color wheel. If color seems to drift across screen or there is a loud-ish whining noise from back of TV that you can here clear across a room, then this color wheel may be bad. They wear out.
It sounds like the main power supply has a bad capacitor. its a typical issue with a lot of electronic. look on the main power board that the outlet cord comes in to the TV and check all the cylindrical components for swelling, leakage, or singe makes.
It's not the lamp, most of the time they suspected it and the fan gone to malfunction when encountered this kind of symptoms but the fault came from the color wheel. You have to replaced it to resolve the issue.
This tv have a colors wheel is dying and worn out.The sound u hear buzzing,squiling or lound motor noises.The colors wheel require changing,because it dying and spinning off of it motor axis.Hire a tv Tech. to change the colors wheel,because it sit way inside near the Light Projection Engine it self,require take out many machanical parts even can come to the colors wheel itself to change it.
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.
Remove the lamp---it is customer removable---- The color wheel will be able to be seen--it will face the front of the lamp.
In case you do not know the color wheel is a round plastic wheel with different colored segments--
What you are looking for is are any or most of them shattered--anything short of the complete wheel will cause the lamp to go off---set will detect the wheel not moving correct and shut lamp off---color wheel turns at over 12,000 rpm.
Some sets you may need to use a small mirror to see the wheel.
If it is damaged you can based on your model number find one on the internet--lots of places sell replacements.
There are also several sites that have printed and even Video instructions for the replacement of the wheel--this is the least expensive way to get this fixed. Most of the wheels run from about 90 -130 dollars plus shipping.
Confirm actual model number and VERSION number that will be on a label on the right side and or the back of the set.

Unit does not have a flywheel. Assemblies include lamp, ballast, color wheel, dmd board, light tunnel, main and/or digital and analog pcb as well as power supply. These are all the assemblies in DLPs. The problem you described is usually lamp or ballast, but can also be from dmd or other circuit boards. Make sure lamp cover door safety switch is secure and fully engaged after replacing lamp or removing rear cover. I admit these sets are not cheap to repair. Good luck, Russmann.
If it is it will be the first I've heard of one shattering... The CW spins at 7200 rpms and at that speed anything is possible. What color is the glass?? Clear and it's not the CW.. My bet is on the lamp. Does the lamp fire up?? You need to do a bit of investigating and let me know and I'll try and help..
it is not related to the failure of the fan or color wheel by anything other then the age of the set..the lamp has a normal life of 4000 to 6000 hours and since your set is around 3.5 years old it probably has that amount of time on it..the lamp is consumer replaceable and many places sell them..the lamp number should be on a small sticker on the side of the set
