The previous owner of mine did the same thing. I ended up using some epoxy to keep it all tight.so i was able to remove the rear dome assembly and switch to leds. after replacing back the assembly, after awhile the back portion of the assembly falls down 1cm and is loose... i checked for breaks in plastic and did not find anything wrong. i do see 2 prongs in the back.
How do I get the assembly tightened?
