This is a possible fault in the power supply, and can be a problem with some decoupler caps on some of the boards. The vertical bars and unstability are usually attributed to having high frequency noise and or clocking pulses crosstalking on to the power distribution lines that run through the boards. This can be switching power supply noise, or cross-talk from clocking pulses.

Another thing that can cause your described fault is unstable clocking between the devices that are reading and writing to the data busses. There are a number of data busses running through the set for the boards to be able to communicate with each other.

The tech will use the process of board swapping to service the set, and then do the adjustments as necessary to make sure the new boards match up.

Yes... DLP sets are fairly expensive to service!

This is my personal opinion. If the set is out of warranty, I would change for a Plasma or LCD set. If you compare the performance of these to ther DLP, the difference is very big. From what I am seeing from a service point of view, the DLP's are lower in reliability.

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..
