Samsung HLN507W freezes with black and white specks

I have a Samsung HLN507W without problems for 4 years plus. Today it started a black-white freeze pixellation and wont turn off unless I unplug it. What is wrong with it? By the way, color wheel seems ok and is not noisy.

    Frozen Pixellation ocurrs and is all black and white as previous poster described....I thought perhaps it was an isue with my cable provider as it seemed to happen only on certain channels.



    I had a tech come out....did some minor adjustments but really not much use; did tell me that he fixed some interference and just tightened the cable connection (I felt a little stupid for that one). The problem didn't go away but became less frequent. I think something with their signal may initiate the problem. It has been much better and that was 2-3 months ago I had them come out.

I had the same problem. It ended up being the DMD board, which is the mirror engine. cost about $1000 to fix. Better off buying a new tv.

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.

I think you have a colorwheel with bearings that are noisy and theres no telling how long it will last . Could be days or years, just noisy. But a colorwheel will not cause a picture to freeze. Sounds like two problems- a questionable colorwheel and a failing dmd board .
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 has few common problems.
HLM437W HLM4365W HLM5065W HLM507W HLM617W HLN437W HLN4365W HLN467W HLN507W HLN50665W HLN567W HLN617W ( L2 and L5 chassis )
SYMPTOMS:
-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 right 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 if caused by DMD board).
Hope this helps someone..

My Samsung HLN5065W started to freeze to a black and white


I have a problem with my HLN 5065W Samsung DLP that 3 other folks have and no solution. After the set is on from 5 minutes to 6 hours, the screen will freeze in black and white, I can turn it off for 5 minutes and it will display a good picture again. Sometimes the screen will just go dark blue, TV has to be cycled on/off to get the display back. This problem is getting worse, started as once a month, now 3-5 times a day. I have a tech background and can read a schematic, HELP.

Picture freezes Black/White


It's most likely the digital board, Samsung p/n# Bp94-00385a but I'd trace test both the digital and analog first before blindly replacing it - too costly to just guess..
