Do we have manuals of how to repair a device?

Do we have manuals of how to repair a device?

Unfortunately not, since we are fully focussed on delivering the right items for a repair on a particular device and not on how to do the repair we do not have the manuals but there are a lot of good websites who do have the manuals. Also if you browse the right product on YouTube there will be a lot of handy videos of successful repairs.
