My ancient but still functional Proxima DP6150 has started to show some problems which seem to be relatively common with this series. The left side of the image has what appear to be convergence or color shift problems, while the right side sports a somewhat noisy vertical purple bar. The purple bar is a recent addition (it appeared when my daughter had left the thing in standby mode for a few weeks), the color shift/misconvergence has been there from when I bought the thing for next to nothing a year ago.
This is what it looks like on the left side (and no, this is not the normal projection surface...):
And this is the purple bar on the right hand side:
And, for good measure, here is the entire projected image:
I know about the solder problems this model has. I have not opened it up yet as I have a few questions before I put the thing under the knife/screwdriver/soldering_iron. For one, there is the ever-elusive service menu. As I do not have the remote control which seems to be the key to enter that menu I have not been able to check whether this menu a) offers any convergence controls and b) whether those controls could be used to solve this problem.
Another problem is has from when I got it - which is possibly related - is that the keystone controls show some strange effects on the blue channel. This picture was taken with the keystone correction maximized in one direction:
This picture shows what it looks like when keystone correction is maximized in the other direction:
This shows the blue shadow which appears when keystone correction is used, as well as the fact that the purple bar is aligned to the LCD pixel grid, not to the projected image. Clearly some of the problems (eg. the blue shadow) lie in the video processing chain while others (the purple bar) are caused by a problem in the display engine. But wait, there is more! Have a look at this image:
This shows a yellow ghost image related to the projected 'P'. With maximum keystone correction the 'P' itself is not aligned to the pixel grid but the ghost DOES follow the pixel grid...
So my questions are:
1) as this seems to be a common problem, what is the usual solution (other than 'buy a new projector' or 'take it to a service center' or 'make sure you have it plugged in' or some similar 'FixYa' solution...)? Some of the effects - eg the noisy purple bar - could well be caused by the bad solder flow job which these projectors seem to be known for, but I'd like to have some more input from those of you who have serviced these projectors before I put the circuit board in the oven...
2) does the service menu offer anything worth my attention to solve this problem?
3) is it possible to enter the service menu without using a remote control?
4) does anyone know the remote control codes used for this projector? One of my phones can double as a universal remote control, so if I know the codes used I might be able to fool the projector into thinking I have a 'Batmouse III' remote control in my hands... There are some Proxima models in the list at a well-known remote control site but none for this model or its equivalents (Ask C100, Astrobeam X210, ...).
The service manual for this thing seems to be available online, but only behind some silly pay walls. Does anyone have a PDF handy which they could send me? I don't know if it contains anything worthwhile but is is always better to be with than without...
Thanks in advance,
