The little rectangle things are capacitors....and very sensitive to static electricity. Some of the components may not be soldered. Sometimes a silver dust impregnated epoxy is used, and can only be removed with heat. (conductive epoxy).
You would need to get the epoxy to about 200°C, and not damage the circuit board substrate in the process. Not an easy task, and now you see why warranty work doesn't go to the component level on boards.
To use those caps, you'd need an LCR meter or some such tool to determine what they are. I used to use one to 'match' them to the proper values.
