Samsung dlpHLN507W picture freezes w/ black & white pixalated

My samsung hln507w picture freezes with a black and white pixalated image of the last screen. I replaced the lamp about a year and a half ago when the three leds lit up. The tv worked but I never felt the the picture was as bright as before, now I have this problem, I switch between the two lamps and both give me this problem after about 5min. Any help would be great and I'm quite happy with a soldering iron and screwdriver.
Thank you for any help,
Pete

Samsung DLP picture keeps freezing


The problem is either the color wheel or dmd board. Both parts are expensive so I would recommend contacting a Samsung authorized repair center. You can call 1-800-samsung or go to samsung-usa.com to find a service provider.

Samsung tv HLN507W. Started out 6 months ago making a humming noice. Now it the screen freezes and goes black and white and the 3 buttons in the front are blinking. We turn it off and it will work for a...


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..

Samsung HLN 4365 wxixaa with Light engine failure????


When the tech said light engine what he ment was DMD board, the DMD board is the most important component on the light engine and most expensive, but still a lot cheaper then the entire light engine.

The DMD board can definetly, and often does cause intermitant errors. Your problem is absolutely not the Ballast, all the ballast is supply the power to turn on the lamp.

Your tech was right to go to the DMD board, the only other option that it could be is a digital board, you would have to see if it is doing this on all inputs.
