Question about Samsung HLN437W 43" Rear Projection HDTV

1 Answer

Picture freezes Black/White

When I first turn on my tv I get a great picture. At no specific time the picture will freeze in a photo negative black/white or some times gray picture. I can still hear the sound and change channels but the frozen picture remains the same. To temporarily solve the problem I have to turn off the tv and re start. The problem does return. I replaced the bulb but this was not the problem. Help

    KCStar, did you get this issue fixed. I have the same black/white freezing issue on my HLN507W set.

    I have hln507w exact same problem, I installed a new bulb.No difference. Reseated all connectors. No difference.Operated TV with back removed and large air flow volume from external fan ( in case problem was heat related. No difference. From various web sources I can assume problem is a result of faulty digital board or light engine. I can't afford to be wrong.

    Not sure what to do


    Let me know if anyone can solve this problem

    Check your cable feed. Make sure you have a direct run from cable box to each tv. To date, it has solved my problem. KC Star

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..

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 to find a service provider.

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.
