Samsung HLN467WX/XAA Picture Freezes

[Todd]

I have a Samsung HLN467WX/XAA that the picture freezes to black and white
snow after about 15 minutes of being on. When it freezes the power,
channel, menu, and volume buttons do not function. The sound continues to
work, and it will eventually turn off the lamp and allow the fans to cool it
down. I have also had it just shut down within 2-3 minutes of being on, and
the timer & lamp lights were flashing green, and the temp light was flashing
red. All fans are working, the color wheel was replaced about 6 months ago,
and the bulb was just replaced a couple weeks ago. Any thought on what it
can be? I have read that the light engine is the problem, but what in the
light engine causes this? Is it a repairable part? Thanks

The problem exists using a coax cable input or a component. The on screen
menu will not pop up on the screen once it freezes in black and white.

Possible DMD defect which is part of the light engine, however it may be a
problem in the digital board.
Does the B/W affect the on screen menu when selecting menu from the
remote? I'd probably try the analog and digital boards and confirm that
the symptom is not specific to just one input such as HDMI or Component.

Does anyone have a service manual for this? These Analog & Digital boards
are still a couple hundred bucks a piece. Is anyway to check any or
troubleshoot any of these boards?

Suggest trying both the Digital and Analog boards as a pair, installing a
new digital board without the analog may cure the picture problems but may
leave you with a set having a no-audio symptom.
Digital: BP94-00385A
Analog: BP94-00434A
