Question about ASK Proxima DP6860 Plus Multimedia Projector

1 Answer

Discolored image and lines...

Without even a source I can see a pink / red haze on the right side of the projector and as it heats up, lines and distortion becomes greater, mainly on the right hand side of the picture. This is from the default Proxima screen. And is the same if I plug in a source (so its not a bad VGA cable)

- I have replaced the lamp, with no change (it was just as bright)
- Does not appear to be anything on or stuck behind the lens from what I can tell.

I'm concerned there is a image sensor problem any thoughts on exploring this more?

    I am having the same issue and have also replaced the lamp with no luck. The lines are pink, blue and purple and are all over the right side of the screen. Any suggestions?

    Same problem...Projector works great for about 2-3 hours, then the vertical bars start appearing on the right side of the screen(projector is mounted on ceiling). The problem continues to get worse over the next half hour, until its so bad that I shut it off. What gets me is that after the unit cools, the problem subsides until it gets hot again. I picked up a DP6850 for parts, hoping it would have the same main board to swap out, but it is a different setup. I swapped out the optics since they are the same(LCD panels and lense are all one unit) hoping that it would fix the problem, but the LCDs are all out of alignment. They are soldered to the optical block, and that is very difficult to align. This is a crazy question, but does anyone know if the lcd panels can be aligned on the firmware/software side? Also, is there a service menu for this unit, if so, what is the key combo to get to it? Any help would be appreciated.

    I've been having a similar problem with my proxima dp6155. I got it used, and it worked just fine excep for a thin blue line on the outside of the screan, on the left hand side. Now I've had it for about 4 months and use it often. After having it on for a a wiel makes the colors kinda seperate. The time it takes seems to be random. It start with a little flickering of the colors, and its kinda like a shadow, and gradually gets more prominent with time. It dousnt seperate more and more, the colors or shadows just get brighter. I know a little about electronics so I disided to crack it open. I checked the circuit board out and didn't find anything burned out. I know the lamp has nothing to do with it, and the lenses don't cause that eather. So my conclusion is a heat issue. Ither the lcd's start malfunctioning after they reach a certain temperature or something running them. I have no clue how thes things work so I cant really do anything els with it. The weard part is, if I leave it on stand by the next time I power it up the problem i worce. If I turn the main swth of, or unplug it, I will go back to normal after I let it rest for a wiel. So thought It was something to do with the power converter or something besides the lcd screen aperatis. So, I added a fan in that section to keep it running cooler, but that didn't solve the problem. I know that sometimes when video cards are acting funny it's becase the memory is going bad, over-heats, or one of them blew. Could this be the problem?

    Also, acording to other postes I have read it seems o happen to units that have had many hours of use, Sometimes its because of dust build up or poor coolong. I on the other hand know as a fact that that is not the case here. I didn't actualy test the board for malfunctions because I really don't know what I'm looking for. Can anybody shed some light on this weard fenominon?

Red haze at bottom of screen

Shut down the projector and allow time to cool before the lamp is taken out to be examined for any dis-coloration. If so the lamp needs to be replaced, try to test using a leased lamp to confirm Also check for shift in the alignment of the lamp settings and also the Lamp alignment.

Multiple reddish pink vertical lines going from


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

Blue haze in top right of screen from NEC mt1075 projector

the light filter on the blue lcd panel is fried due to excessive dust and heat. clean out the projector with canned air. unfortunately, you cannot buy individual parts of the optical engine- you'll have to replace the whole thing. or live with it.

Duplicate image in pink displays on the screen.

From your description, it sounds like an alignment problem. There are 3 LCD panels in the projector. Each one displays an exact duplicate image of the others except it's either red, green, or blue. Under normal conditions, the images precisely overlay one another so you get a sharp image. Due to age, heat, or vibration/shock(impact) it would appear that the red LCD panel has shifted a little, giving the "ghosting" effect. You'll have to have the unit repaired by a qualified tech. He'll have the special electronic equipment needed to align the panels properly. Before sending the unit in, try a reset in the menu. Sometimes, the projectors can shift the image electronically, using math algorithms which will try to auto-sharpen the display. Hope I was able to help!---Rick

Images has a blue color across the center

Wow, 3 in a row. As described on 2 other projector issues this is very similar to those others. I'll repeat the info here.

I assume this is an LCD. I don't remember the s4 being a DLP projector.

This sounds like the LCD panel used for the blue color has gone out. The image is made up of red, green and blue images layered upon the screen. If the blue panel has gone out then there is nothing filtering out the red light in the image.

It looks like yours has just a secone of the panel dying or comming loose from it's connector.

It could be a simple open and reconnect fix. I personally have never opened a projector, so I'm not going to walk you through it as I do not know how hard it would be to tinker with. It should eb a cheap fix for a true repair man though.

You have not set the port on the back of the projector settings.

Go into the projector menu and go into the IMAGE area. Somewhere in here you should be able to select computer.

LP690 projector displaying strange lines

to adjust those mirrors, you need to power down, unplug, remove the top, remove the wires from the main board, remove the main board, adjust one mirror, reinstall everything, power up, see whatever difference it made, power down and repeat until it's fixed. it's quite a chore. if that's not the problem, you'll need to replace the optical engine (which isn't cheap) because they don't sell individual parts.
