Interesting post on the AVSForum regarding using the VGA input and a solid black screen to "clear clouds."
It has been confirmed to NOT work, furthering our belief the defect is hardware-based.
" IT'S OFFICIAL! "PC input"MAKES NO DIFFERENCE whether you are watching through the PC input or any other inputs, THE CLOUDS ARE ALWAYS THERE, and will always be there....
I connected a PC via VGA to a 46" XBR2 AUGUST build(with slight clouding on left side). And I used a program called "DPT" http://www.dps.uk.com/freeware_DTP.htm
to test for dead or stuck pixels, it allows the screen to be completely black, with no windows borders showing on the outside. This program created the ideal Black screen to test for clouds.
People, make sure through a pc you have NO windows borders with START at the bottom of the screen, SCREEN must be completely BLACK. THIS is why the "DPT" program is useful.
In my tests, I had PICTURE turned up to max and Backlight to max... Clouds were clearly visible just like Cable thru HDMI and component!! The PC makes no difference!! The software Patch may also make no difference!! The panel is physically creating the clouds."
