How to remove rear cover samsung HLR6768W?

Possibility (one screw behind a piece of tape or other manufacturer icon) Also there are some with a couple snap together clasps that you have to be very careful to get open with small screwdriver. Be sure if this is a CRT television that the screw that fastens to the flyback transformer is out. Some also have a screw or three in the front where the power button, channel & audio adjustment are located. Just a few places and things you can check.

Hlr6768 Fans and Color wheel turns on full speed as soon as it's plugged in.

Whenever you attempt a repair and have new issues ( yours is a duzzey) stop and step back and look over what you just did.

Possible reasons for this:

A bolt of lightening struck and by chance just after you replaced the light engine--not likely.

I would (serious note) BACK TRACK and remove it checking all cables and connectors are plugged in and in the right place--the whole engine in most of these slides in and it is easy to miss something or tangle some wires etc.

the other two possible reasons are = the new engine has a defect, strange and odd but odder things have happened.

The engine does communicate to other boards and anything you have already replaced is suspect.

Hope you get it sorted out but likely it is man made--happened in the course of your adventures at trying to fix it.

Loud noise, line on the left side, no color

It sounds like the color wheel has fallen apart and will have to be replaced by a technician. The line could be from the color wheel or from the light tunnel. You can call 1-800-samsung for the nearest service center.

Turbine/moaning sound and vibration

The grinding sound that you are hearing is your color wheel. They can make a noise from a buzz to a power saw type of noise. Usually the set will continue to play with the noise, but it is annoying. You will need to replace the color wheel now.

This is not as easy as the lamp replacement, as you have to pull the light engine to access the color wheel. It is not hard just more work and be careful of the color wheel lenses.

I hope this information allows you to resolve this issue.

Samsung 6768W DLP 2 yrs old Replaced lamp and now color is off Faces look like paint by number

possible solution:

  1. 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 calibration device.
