This is a new thread to focus on the current status of the problems seen by 7UY owners primarily with s-video sources.
An updated summary of s-video problems and a comparison of different input sources and panel settings can be found at this website. This web page will continue to be updated with the latest testing results:
Problems with the Panasonic WD7UY EDTV Plasma Display
(http://www.lakemercedcoc.org/plasma)
These problems include:
1. Glowing bars from the top and bottom of the screens as bright objects appear in the scene. Most noticeable in letterbox material which provides a dark screen area at the top and bottom of the screen.
2. Brightness banding when there is a high contrast between dark and light objects on the screen (aka "Brightness Bleed").
3. Brighter Corners depending on content. Very noticeable in darker scenes. For example, the middle of the screen may appear a solid black where the corners are a dark brown, but also seen clearly even with completley bright scenes with moving content. The higher corner brightness seems to affect all colors.
These problems appear in all input sources (composite, s-video, and component), however are most noticeable in the composite and s-video inputs. The component problems are to a much lesser degree and not noticeable when watching most source material.
These problems have also been reported by owners of both the WD7UY and HD7UY models in the 7UY series. A few owners have reported that they do not see the problem.
I encourage all owners who are affected by these problems to contact their vendor and Panasonic to let them know of this problem. To date, several owners and Visual Apex has been able to easily reproduce the problem. Panasonic is aware of the problem but has not provided any confirmation or statement on the issue.
Please continue to post your interactions with your vendor and Panasonic in this thread so all owners and prospective future customers can be kept up to date on how this problem is being addressed.
Thanks.
