Mike,
You did wonderfully!!! I thank you very much.

Frankly, I'm not sure this is something that will affect the average user, but is attention to detail we want to imrpove. I made sure your information made it to the correct circle of knowledge. :)

With your information and the few serial ranges we have, Philips will be able to isolate which time frame the screens came in and further the testing from there to narrow it down.

We may never see the results, but future users definately will!!

Yet another fine example of this user community coming together. Thank you all for valuable input.

Lisa
