My digital clock light is not working. I followed a couple of threads in the forum and now i know how to change that LED on the back of the clock. I have a couple of questions. Where can i buy the bulb and other thing is, what should I ask for? ( I mean LED model number ). Also accidentally my LED dropped inside the vent that the digital clock is placed when i was taking it out, is it going to cause any problems, if so how can i remove it? Thanks
