Re: picture loses color on samsung HLN4365W

If the picture is still visible but lacking color, it is not the lamp. check the color wheel and make sure it is working. replacing the color wheel is a pretty easy task and can be performed by yourself without many problems. as a sidenote, older samsung dlp tvs seem to experience this problem quite often, although they usually sound like someone strangling a cat before the bearings go out.. should carry your replacement for 100 USD or so, the part number is BP96-00250A.

before replacing it, make sure your old one isn't just stuck or not spinning at full rpm, if this is the case, you can usually remove it and clean the motor using electronic or contact cleaner that is safe for plastics.

to check everything out, you will need to remove the back panel of your tv, then power it up (keep kids, small animals, hands and such away from the back while powered up), take a look in front of the projection lamp and see if the wheel is turning. if not, a very good writeup is available here, this is the writeup i send my own customers to if they feel like attempting the repair themselves.

replacing the color wheel is actually not very hard at all, if you have ever worked on your own desktop pc (installed a new drive or upgraded it yourself) then you should be able to do this with limited difficulty.

hope this helps,

I have a 43 inch samsung DLP tv 2004 model# HLN4365W, I was getting a black and white picture, so i replaced the color wheel which was broken. It worked fine for a couple of days then there was no picture,...

No picture on a DLP when you can see the lamp is working is ALWAYS the DLP chip. BECAUSE you recently replaced the color wheel, i suspect that the LVDS/data cable to the light engine was not plugged in well and has come loose. I suggest checking and rechecking every cable and plug you can find.

Most likely your problem is on the DMD Assy Board P/N BP96-00249A . More presicely there is a few bad electronic components on that board that are bad. That board can be repaired by replacing the bad components (and the other few compoonents that are probly going bad and will soon cause your tv to lockup and lose remote and button functions when it fails so you will need to unplug it to get it on again).
Or the DMD board can be replaced .But it is not a cheap board.
For removal and Installation of the DMD board I would reccomend a tv service person because it is in the heart of the television and there are some adjustements to be made when the new board is installed.
To get the new board you could probably find it by just gooogling the part number.
Component level repair would require some experience in desoldering and soldering SMT,SMD , and or surface mount components.The actual components are about $15.00 total so just repairing your board should cost about $125.00 by a qualified servicer (if you were to remove and install it yourself). This DMD board is used in many models and can a few common problems.
HLM437W HLM4365W HLM5065W HLM507W HLM617W HLN437W HLN4365W HLN467W HLN507W HLN50665W HLN567W HLN617W ( L2 and L5 chassis )
-Intermittant picture freezing with a negative looking B/W frozen picture.
-Intermittant loss of pic with/without shutdown,abnormal color wheel noise if attempted to start after shutdown.
-lockup of tv control functions . Remote and front keypad do nothing , TV must be unplugged to reset .
-horizantal tearing, distortion , flippnig , solarization , red picture, leading to blank screen and lockup.(tv menu would be affected by all picture defects).
Hope this helps someone..

The sound comes from the color wheel and not a fan,common to samsung dlp tv's which can be the cause of the shut down.

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.

These sets have a color wheel in them that has been know to cause this, Many times the customer heres the color wheel bearings failing and think it's a fan failing. The part BP96-00250a is only about $95.00 and since I have changed well over a hundred would call this a easy repair but for the newbie this might be a challenge

HLN4365W Picture goes askew and turns to black and white.

Hi...what you are seeing is the DMD board (digital Mirror display board) going bad. And if you leave it turned on like that it will damage the DMD mirror and freeze that picture into the mirror. It will look as if someone etched it into the mirror. DMD boards can be repaired and some cannot be repaired. The DMD board can be replaced. The DMD mirror can also be replaced too.

No picture, new lamp

Did you reset the hours on the lamp with the menu options on your set? Sometimes, if you do not do that it can mess with the tv performance thinking that its over hours. It needs to be reset to 0 again...
