It is a power issue. Either the power supply or the ballast. In instances like these it is usually a blown cap or two somewhere. It has not happened to mine yet so I can't comment on where to start looking.
This is a problem that will need to be addressed by an authorized repair facility. It is a failed Digital Micromirror Device (DMD) and the entire DLP board around it will need to be replaced. A board that is only sold to authorized repair centers and a part that you can not find anywhere on the internet.
My best advice to you, if you'd want to attempt the fix yourself, is find another hc1600 with a different problem and swap the DLP boards.
I'm new here and wondering if any of you experience the problem I'm having with my HC1600. Everytime I hook it up to my Windows 7 computer it does not get detected until I restart my computer. Any thoughts on this? Is this expected behavior? This did not happen when I used to have Windows XP on the same PC. With XP, I only needed to check "Extend my Windows desktop onto this monitor" and it works. No need to restart.
Tint and Color are from the analog days, If you use a component (non HD signal), composite or Svideo you will have access to those controls but . HDMI or VGA you will not as they really have no place in the digital world. TV makers are adding them in newer sets because people think they need them when in fact the do not.
