Yep I don't blame you - even if its out of warranty, did you ever ring or email bosch? "some times" on very rare occasions these nice big companies can show a side of compassion towards the people who buy their products and if the display was supposed to be water proof or resistant, they may consider giving you a new display, I find the earlier you ask out of warranty the better and just on the odd occasion I have been known to mention that I "might" be doing a Youtube video featuring said product and then, only sometimes a nice new part appears like magic in my posties hand!
