I have a 24" Dell LCD (IPS panel based). When it was new, the Calendar gadget gave it IR. I just ran the built in "rotating color slides" (they call it LCD Conditioning) ... and it fixed/erased it.
Take a cue from the plasma guys. They have a set of rotating color slides you can download. My plasma has a built-in IR-Eraser ... just a thick white bar that moves down the screen over a black background. Sounds like you are running a HTPC, so it would be easy to run something like this.
Thanks for the "heads up" on this though. Since we have had plasmas for over 5 years now, we have trained ourselves to zoom 4:3 content and turn the screen power off if paused for long periods. Thankfully, now-days, we mostly watch digital 16:9 TV or movies with minimal bars.
I had noticed this behavior and for months attributed it to weirdness with my HTPC. However after a new HTPC was installed I noticed the same behavior and then when the image retention carried over to another source (Blu-Ray) I then starting checking the rest of the setup. After various source switch it became clear I had an issue with the projector.
I called Epson and talked to a fairly rude individual who kept insisting that I let him speak instead of me finishing my full rundown of troubleshooting steps. Nonetheless I ended the call with them offering to send a replacement unit.
I'm worried about the issue coming back though. The biggest culprit is a DVD menu. Scenario happens all of the time in my house, kid's put on a movie and then it finishes and ends up on the menu screen for an extended time. The latest one was Mulan, white background with lots of Chinese lettering which is now ghosted onto my screen when I watch other content.
I had also noticed obvious signs of 4:3 bar presence that I can now attribute to this same phenomenon in all likelihood.
Would be curious if others are seeing anything remotely similar.
