If there are any more detailed results about “Do not submerge the display or camera modules, even if they are damaged.

This might be useful for other type of repairs, e.g. LCD video projectors. It is a common problem that the prism block (with the LCD panels) will be stained with dust and nicotine (tar?). I know no official way to clean such a prism unit and replacement is far too expensive…

Kenwood’s service manual specifies to use 133gr (4 3/4ozs) of Shell L.G.P.1 62814 or Shell L.G.P.1 62819. I was not able to find the specs for this grease. As the separation between the gear box and the food is properly solved I think the use o food grade grease is not mandatory, but I would recommend it anyway.
