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.

Its probably unrelated to lamp, take the lamp out, try it again and look into the lens, if its still very green the projectors electronics are failing. The projector generates pictures as 3 streams of info Red Green and Blue. It looks like the projectors red and blue electronics are failing, but the green is working.
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
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,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!
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.
