Samsung 6768W DLP 2 yrs old Replaced lamp and now color is off Faces look like paint by number
Samsung HLR6768W Lamp was replaced but now we can't get the colors synched up. Some colors are bright, some are dull and it depends on if we are watching HD, a DVD or a non HD channel. Faces look like paint by number, no blending of the colors. Any ideas?
You may need to
adjust the index delay after the replacement. You will be able to tell
because you may see strange color banding in any scenes that have colors
close, but not quite the same, in tone. This is usually most obvious in
face skin tones (i.e. “clay faces”). If you need to adjust index delay,
turn off the set, wait for the lamp to cool down, then hit
mute-1-8-2-power in succession. The set should turn on with the service
menu popping up eventually on the left. I don’t remember which submenu
“index delay” is under, but find it and usually it will need to be
lowered. I believe mine started out in the mid-50’s and had to be
lowered to 47. These numbers are different for each Samsung model, so
just adjust until the picture is pleasing to your eye. By the way, the
supposed “correct” way to do this is to make the reddish part of the
test color bar appear the “most saturated”, if you have a color
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Sounds like a bad color wheel----remove lamp---the wheel faces it--look for missing pieces or the wheel shattered---these are known for the wheel making a loud high pitched sound or even a grinding sound if the wheel shatters.
if wheel bad You Tube has video instructions for replacing it---seen several people able to do this themselves in about a hour. Google the model number to ("color wheel") to locate a replacement on the internet.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.Have a bless one!
Hi,Is your tv close to 6000-8000 hrs 2-4 yrs.If its it might be time to replace the lamp.Your part # is XL2200 Make sure you get the Philips lamp.There's other components that tend to go bad like the ballast which is the board that powers the lamp.When that is bad it will make continuous clicking noises or attempts to light up the lamp.But if you dont hear any of that then most likely its just the lamp that needs to be replaced.Have a blessed one!
Hi,If your tv is between 2-4 yrs most likely it's time to replace the lamp.If you hear continuous clicking it could be the ballast which is the board that powers the lamp.If you hear buzzing it could be the color wheel,which is a spinning wheel that creates the color on your tv.God bless you!
Remove the rear cover and check the lamp cover switch. Earlier versions used a black plastic switch holder that may break due to improper assembly. The part number for the holder is BP61-01240A. Newer versions use a metal tab attached to the engine. In this case, improper assembly may cause the lamp cover switch to be extended past its range, either breaking the switch or causing it to have an open contact. Replace the switch with BP91-01231A.
Note that in these models, when reinstalling the rear cover, it is best to remove the lamp cover first, install the rear cover, then install the lamp cover. This will make sure that the lamp switch is properly engaged.
You will need to have it diagnosed if you do not have the service manual, or the knowledge of how these circuits work. I can tell you to replace this or that but it would be a guess! You need to start measuring the voltages on the ballast circuit, as I have seen door switches, fan sensors, heat sensors cause all of your symptoms as well. Good Luck
