There are three ways to repair a broken item:
1) by yourself if you have the relevant knowledge and skills;
2) to use electronic repair guides offered online;
3) use the services of real technicians.
Electronic equipment contains dangerous voltages and can be hazardous to unqualified service personnel. Only those with adequate training, equipment, facilities and experience should attempt to repair any electronic equipment. Anyone attempting to repair any electronic equipment who does not fully understand the shock hazards, as well as the fire hazards associated with working with electronic equipment, should not attempt such procedures! Improperly attempted repair can kill you and burn down your house.
That is why it is better to order the services from specialized companies. Such companies offer on-site services as well as take the damaged item to their facility and then ship it back when repaired. Such companies are numerous and their prices vary considerably.
