Did you change both R1 and R2 resistors?
Also, any detailed info you may give about the best way to desolder and solder the new crystals and resistors in would be hugely appreciated. What i really need to know is how much heat can these little crystals take?
Just look up how to desolder (input item name)
I have done that. Theres seems to be a lot of varying methods/techniques to do the job. I wanted to know from those that have completed a successful crystal change the best method for changing them out on these miners as the location of the crystal is very close to two capacitors at the left of the crystal itself (plastic tweezers?). I wished to know the right amount of heat to apply in case i ended up damaging components.
