Good Job, Parasuraman. Concerning Albert´s comment, I´ve also repaired many RCs by adding graphite powder, generally with success. Only one went bad: perhaps the excess graphite powder created a wrong bridge that caused the RC to maintain the transmitting LED on continuously. Even opening again the gadget and doing a careful inspection, the wrong bridge could not be find. I did a complete cleaning trying to remove the excess powder, but nothing. As I had another spare RC I decided to not lose time anymore on that faulty RC.

Yes, strange as it might seem, number of cases of failure of crystals is on the increase! Might be due to climatic conditions too! Thanks, dear Mark!

Adding graphite powder might be ok. But matching the resistance would be difficult. Many thanks for your comments, dear Albert!

I have never had to replace a crystal yet while repairing a remote. Good job in the repair.

Most of the time it are the failing silicon/rubbery pushbutton pads on my IR remotes. But the recent tip to add new graphite powder onto the conducting contact pads using cotton swabs was a very good remedy! Hope it will last for a very long time.

May be climate conditions also do contribute for such failures! But may I a wish you get a chance to replace crystals in future! (LOL) Thanks for your comments, dear friend!
