I've had my Samsung 61" DLP TV for over 3 years and after 1.5 years i noticed on occasion that i would lose all red and pink color suddenly which would leave the screen looking very green. A simple turning the TV on and off would fix the problem most times. After seeing the problem for a few months it went away for a good 6 to 9 months now the same problem has returned, worse then ever meaning most times when the tv is turned on it starts with no red or pink and tuning the set on and off does'nt fix the problem anymore. At times i also noticed the red trying to come back with visual flickering but for the most part the past 2 months i'm stuck watching Movies and TV with a green tint that i can't change or get rid of no matter what i try. Any suggestions on what happening and what i can do to fix this problem?? Thanks Jay G.

No. This is a DLP TV. It gets it's color by a color wheel. If color seems to drift across screen or there is a loud-ish whining noise from back of TV that you can here clear across a room, then this color wheel may be bad. They wear out.
Had similar problem. Thought it was the lamp. Examined old lamp but it appeared to be good. Ordered a new one anyway. Changed the lamp but the TV screen would not come on. It would make the usual noise as it was going to come on normally but it would cycle 3 times & then turn off. The LED lights in the front panel would indicate a defective lamp. Then read about the ballast. Changed the ballast & still same problem. Tried starting the TV without the lamp installed & noticed that the color wheel did not spin. Removed old color wheel & discovered it was broken. This appears to be the cause of all of my problems. I wish I new earlier of the test-turn on the TV without the lamp being installed & check to see if the color wheel is spinning. Would have save money on the lamp & ballast.
If you are using Component inputs, check to make sure that the Blue Video Cable has not backed out of its connecting jack at either end or the cable it's self being bad. If you are using HDMI I would suspect that the Digital Board being bad. It would be odd for the Color Wheel to cause the problem but cannot eliminate it as a cause. The Lamp would cause the picture to be darker but not cause a color to drop out.
I would call a professional to trouble shoot it unless you have the knowledge and the tools to do so.
Hope this helps,
all 3 lights blinking means lamp has a fault the service manual says replace the lamp. If you need the service training manual for that model let me know and I will post the link as the training manual has excellent trouble shooting breakdowns for that model DLP
