LCD Display Contact with PCB

Jun 12, 2008 6 Replies

My wife dropped her portable radio in coke. I took it apart and cleaned it and it seems to work fine except the LCD Display is dim and erratic. It connects to the PCB lands by pressure only and pressing improves the display somewhat. I don't understand how this type of connection works. I have cleaned both parts but not much improvement.



Any advice would be appreciated. I understand that the acid from the soft drink can dissolve connections and that the sugar will cause shorts. However not much got in and I have cleaned everything else pretty well. Is there some kind of contact grease that has to be applied to the lands to make a good connection?

Need to clean the edge of the lcd in rubbing alcohol. The contacts between the lcd and pcb should be completely free of any substance so it's a no to any contact 'grease'.

Thanks. I also read somewhere that a very fine coat of WD-40 would work... and it did.

Yeah, but WD-40t does work to clean off crud, then should be wiped off carefully itself.
