Question about Projection Televisions
Okay, so my TV keeps flashing mostly in green colors and as one person has put it, it looks like you're watching TV with nightvision goggles on. So me, not knowing anything about these TV's and their maintenance, I automatically thought the projection lamp was the problem but apparently not because I ordered one for $115 online and the problem still continues. Now, I'm thinking that it is the color wheel.
Currently, here is what happens. I turn on the TV and it'll be fine for 5-10 minutes, working great. Then it begin to flash in green and white colors. This flashing keeps getting worse and worse until finally the TV will turn off on it's own. Audio will continue to work though and the power light blinks 5 times, stops, then blinks 5 times again. As it's doing that, the TV makes an odd noise that's kinda hard to explain. It sounds like an airplane is dropping a missile. Like a sound effect on a very old video game.
Okay so once I can find a color wheel for a decent price, where can I find step by step instructions on how to replace this color wheel myself?
If anyone else has any suggestions or any kind of experience on this issue please feel free to add your comments!
the color wheel wil need to be replaced soon if it is doing that. it could be then DMD board as will.

This set has had issues with the power supply. It may have defective capacitors. This would require disassembly and replacement of parts.
Do you have test equipment and a service manual?
If you have a repair shop
do the repair, your cost may be $300.00- $400.00 to repair.
Parts and manuals can be purchased at:

I am not sure about your model but i do know on some samsung dlps there is a dip switch that has to be changed if you have the backwards color after changing the color wheel.I hope this helps.

Replace the color wheel again, its gone bad again. the clicking is the ballast trying to fire the lamp. The Ballast will not fire the lamp until the color wheel has reported it has reached an RPM of around 9000rpm. This is a normal sound. Most of the time the color wheel will make a loud whining sound when bearings go bad, sounds like a Airplane using reverse thrusters when landing and a even louder sound when it shatters in the housing. Also the reason it may of gone bad so soon is because they make to versions of this color wheel, Bearing type and the Air type. I don't know who installed your color wheel, but it should of came with a small tag or paper of some sort with numbers on it. Most people throw this away when it is very important to let the unit know which type of wheel is being installed to set the parameters for either type of wheel. Most people who install colors wheels themselves to save money do not know this, and the only way to install the new settings is thru the Factory Service Mode. There are also color parameters to input for the type of wheel being used.
This is your basic Color wheel 101..
Hope I gave you some insite of what may of caused your problem...Please leave comment if more info is needed..Lavell
