I own a panasonic ptae 100 ,had it now for two years. The problem i have is when watching films with black borders after i switch the dvd player off you can still see the outline where the black borders were. I have noticed this before but normally when i switch the projector off and then the next time i turn it on they are gone . But now they seem to be there all the time. IS there any discs i can run on it to remove them like you can on my panasonic plasma.just to say never had screen burn on panny pwd6. Do you think i can use this as an excuse to buy a ptae700 Just to let you know i have just started running it on high mode could this be the problem? Do lcd projectors suffer from screen burn?
