Those dust blobs can definitely be frustrating. I would call Panasonic and see if they have a suggestion... and if you do take it apart, be careful.
It could be intimidating. My background is electronics so it wasn't too bad for me. I think if you take your time, are careful with the connectors, and make sure to use clean compressed air, most people who aren't too technically disadvantaged can do the job. Read through the procedure and lift the lid. Then see what you feel like. Panasonic will do the job for you but it will cost.Cool. Thanks for the link. That sounds pretty intimidating. Last thing I want to do is make it worse... I might think on that for a while before attempting it. But, it does sound exactly like the same problem (further down the light path than I thought).
Thanks for the feedback!
