[QUOTE=gwlaw99|Aug 17, 2008 4:33:36 AM] I think its time to send it in for warranty work right away. [/QUOTE] I just had the same thing happen with my W20000. (it's inverted from ceiling) so the right half of the screen started to jitter, while the left side was perfectly normal. I first thought it was a glitch on the new blu-ray title i was playing, and then the right half of screen went black. and that was pretty much that. i powered off the unit, let it sit a few minutes and turned it back on to immediately have the right half of the screen covered in alternating black and white vertical line. The left side of the screen was instead a mess of posterisation and what looked about a 16 colour palette. so i've powered off the unit again, unplugged everything and will let it sit a while longer.... BTW when i re-powered it up the first time,after the initial half black screen, the internal sounds seems different to me, as if the PJ was struggling to start something up..i'm pretty sure i heard 3 distinct moans of a power-motor, and then the screen did it's black and white stripe show..... an update on your W5000 problems/solutions would be greatly appreciated.
