I replaced the color wheel on my tv and my colors are messed up b/c I didn't pull my jumper. I know I need to pull the jumper but just not sure which one is the jumper. Can you advise me where this wire is and what it looks like?

Re: Need to disconnect jumper
Jumpers are usually small connectors with built in electrical contacts or connections similar to other wires on the board with a short wire going from one side to another.
Also, if you exchanged the color wheel with a one for one exact match with the old one it may be that you connected it backwards or one pin ofset.
Another option is that most DLP's have an internal offset for colorwheel timing, this is usually in the service menu.

yes , u need to remove this jumper , and the whine would go away , the bulletin is unique for each color wheel , the jumper is very small so just take u time to look for it , is located at the dmd board
You probably replaced a bearing colorwheel, and it was replaced with a bearingless. If you look inside the TV on the back of the light engine (the silver box in front of and to the left of the color wheel), there should be a jumper (that connects two wires coming out) toward the bottom of it in a recessed little hole. That jumper should be removed if the color wheel was replaced with the air bearing type. Just grasp it gently with a pair of needle nose pliers, and pull it out slowly.
This should restore a normal color operation, but there might be some other adjustments that need to be made if it doesn't clear it up completely.
could be a jumper on the DMD board that must be removed, look for a small sticker that points to the jumper, or it could be a setting in the factory mode, mute-182-power will get you in there, check the settings for the color wheel
Hi...No need for a different jumper or different color wheel. It's an easy fix. Make sure your TV is turned off and remove the jumper with a pair of needle nose pliers. Just keep it in case you may need it in the future. I will post a picture to show you where the jumper is located.
Most times color does not to be reset. If you have a very ugly green or blue picture, then you did not pull the jumper on the dm board. This jumper must be removed when a bering type color wheel has be replaced with a new airless bering color wheel.
The jumper that you need to remove is a small usually black block of plastic approx 1/4" in across and 1/8" thick located near the center of the shiny silver colored apparatus into which the color wheel is plugged. Mine had a label that read FDB Bearing Color Wheel, BP67-00099A and two illustrations indicating open and shorted conditions. The label was just over the jumper. I pulled it out with needle nose pliers and the problem was solved. GndLoop
When I removed the jumper wire the screen color problems I experienced after changing the color wheel were fixed completely. I did not need to reset the CCA values (which came with my color wheel, on a separate sticker). If you have a black bracket blocking access to the jumper wire, as I did, you can access the jumper wire by removing the fan shown just to the left of the yellow and white sticker; there are two screws attaching the fan to the chassis below it. Next, remove the two screws that hold the silver clamshell (the housing for the circuit board) halves together. These screws are right behind where the fan just was, on either side of the protruding fins. They each have a spring under the screw head. You can then pull the visible half of the silver housing forward (with the bracket attached). You will then have access to the entire circuit board. Look for CN810 - it is located right behind where that bracket just was when it was all put together. Pull the tiny black plastic part (that has the jumper wire) off of the pins. Then reassemble the housing and put the fan back on.
