Hi, I have an old Proxima DP5950 that has an issue. Using the S-Video or Composite video inputs, my picture is normal. However, if I switch to either of the PC inputs, the picture has a strong green cast to it. Now, be aware, this is without any cables or input sources attached. The problem is present viewing the menu on-screen display. It is like the sub-brightness for the green LCD is set very high. If I selectively block out the LCDs, both blue and red appear normal. However, on the green panel, anything that you would expect to be black, would be a slightly darker green. Again, what makes this strange is that when using either of the non-PC inputs, the picture is great! Anyone got any ideas? Anyone know what the service menu settings are for this projector? Thanks!
