I have a proxima dp6860 color shadow

First thing to try is a convergence but with the red shadowing seems to me that you may have your color gun going. Convergence can be found in your video menu on your setup screen. Once in the menu you can adjust the colors to line up. This usually has to be done on a tv that has been moved.

it's been a long time since I worked on one of these,but if you select the menu and look thru the settings, you should see "ceiling" with a checked box next to it. just uncheck the box.

sounds like you have ghosting, this is not adjustable unless you can get into the hidden menu and then you have to know exactly what you are doing. Or the LCD ribbons have come loose. The easiest thing to try is reflashing the software.

take the top cover off and look for the 3 lcd ribbon cables plugged into thr main board. it is a pain in the ****, but the cable must be completely seated into the things on the main board. there should be little brown tabs on the connectors on the main board that you flip up or down, then make sure all lcd cable are pushed all the way in.

No they will not interchange.

The DP6860 takes a bulb number LAMP-030 and is a 250 watt bulb.

The DP6850 takes a bulb number LAMP-017 and is a 190 watt bulb.

If you could physically make them fit by some means, likely just the wattage difference would cause problems with the projector. These bulbs require much more electronics to light up than what a normal household bulb does. I'm assuming the projector would think the lamp is either burned out or worst case cause damage to the power supply in the projector.

Hi

We can check if the problem is on the hardware(projector) itself or if from source(device connected to projector) try to turn on projector without connecting any other devices to it. If you can still see the pink line- try to remove bulb and reinstall it. If all fails and pink line still visible, there is a problem with projector. If no line is present- check settings and change input signals.

Hope this helps

did u fix your tv cuz thats the same thing thats happening to me

You can fix this in the service menu

I also am having the same problem. at first it only showed up after the projector was on for about 15 minutes. Now I get a purple vertical bar on the right of the screen. I also get vertical green bars spread across the screen.
Does anyone have a diagram of how this machine is assembled?
