Hello, i’m very grateful to find your website. I dropped my AC remote (GYKQ-34) on the floor and it stopped working. After opening it I found the fault component was a long cylindrical metal crystal oscillator. I believe this happened because the oscillator felt the trauma when remote impacted the ground.

These types of crystals seem often tend to get defective after a certain time period. I have witnessed many such failures where those crystals do not experience mechanical shock or ambient moisture absorbed by position fixing glue. As these tend to get defective it is advisable to use a crystal checker. Furthermore I have often experienced resistance in between crystal legs of which failed to operate and few got to function once crystal leads were heated. The best way is to replace one and see the effect in the first place.

In jestine yong xxbasic electronics repair e-book,pg 157,he suggested if you drop crystal on a ground from decent height, there 50/50 chance whether it will function again.

The most common cause of crystals failures in remote controls and wireless phones is the Alberts' reference below. (Mechanical damage of them, due to dropping of the apparatus on the floor)...
