I thought I'd complain directly to Panasonic about the Vertical Banding on my AE500 to see wether they could take it back & tweak it out? Here is their response (about 3 weeks after the initial email). Thought you might be interested ? Thank you for your email enquiry. Firstly, please accept my sincere apologies for the uncharacteristic delay in our response. Investigations of this issue both at the factory and in our workshop took longer than anticipated. After many hours of testing and much careful consideration, our factory have concluded that the issues you have described with your PTAE500 were found to be within manufacturer's specification and tolerance. Therefore, as the unit is not inherently faulty, we will be unable to effect a repair. I asked : Please can you explain what you mean by "After many hours of testing". None of your people have even set eyes on my Projector. I would also like you to comment on the fact that some AE500 Owners see no Vertical Banding & some see terrible banding? It sounds like pot luck to me ? What quality control do you actually employ at your factory to test / tweak this problem ? Regards & dissapointed Thank you for your email enquiry. Both the factory and the workshop have tested other customer units with similar issues and sealed LCD units from the factory. There is a set specification for the LCD unit and the banding has been found to fall within that specification. There are no planned tweaks for this product unfortunately as it is now a discontinued model. As this is found to be within specification and not a fault, the factory does not have any resolution. I am sorry that we could not be of further assistance to you on this occasion. Regards, Jill Farrar Customer Support Looks like we'll just have to accept that VB exists on Panny LCD's. If only Sony's models were Short Throw I'd willingly pay the extra few hundred quid for no VB!
