Windows 7: Monitor suddenly went non-HDCP compliant (EDID corrupt)...

Monitor suddenly went non-HDCP compliant (EDID corrupt)...

Hello!

I'm hoping someone here has some experience with monitors, HDCP and EDID.

A month back my monitor suddenly wouldn't turn on after 19,000 hours of service. Fair enough.

So, I bought a repair kit and fixed 12 capacitators - a common problem with every PSU I have come by.

That worked, and the monitor is running again - a bit yellow tint though due to the many hours.

Thats not the problem.

The problem is that I had to rewrite the EDID after the power down. Somehow it went corrupt and I rewrote it succesfully with the data from the registry.

However, now the monitor displays as "not HDCP compliant" in the NVidia settings (and I know for a fact that the monitor is HDCP compliant and showed up as such before the breakdown). The Cyberlink BD Advisor tool also reports that the monitor is not compliant.

So my questions are:
  • Has the rewriting of the EDID (in service mode) messed up HDCP?
  • If EDID is connected to the problem - how do I correct the EDID?
  • How can a power down otherwise mess up HDCP (hardware failure)?
  • Is there a way to fix the issue at all?
  • Can someone post a link to a movie that is protected in order to check that way?
The monitor is connected to my GFX on HDMI (mini) and I already tried the DVI's and turning the monitor on/off etc. The monitor is a HP w2207h and recognized by Windows as such - original drivers installed (version 3.0.0.0).

Thanks,
