Choosing to have electrical, electronic, and computer equipment repaired is a decision that sometimes has to be made, and given the issues involved it can be difficult to make that decision.
Repairing an item can sometimes be cheaper than replacement and it is often a more environmentally friendly alternative. However, with the rapid changes in technology repairing an older piece of technology may not be viable. For example, the older CRT computer monitors are bulky and use more energy that the newer LCD monitors. Therefore, if a CRT monitor fails it is usually better to upgrade to an LCD monitor.
In recent decades it has become more difficult for technicians to repair equipment for a number of reasons. Modern technology is often complex and requires specialist training, data, and equipment to carry out repairs. Sometimes manufacturers do not release service data making it difficult for both authorised service agencies and third party organisations to carry out repairs. The Repair Association is advocating for legislation that would allow consumers and repair organisation access to service data.
The complexity of the repair process is made easier with the advent of the internet. Solutions to faults are often shared in online forums allowing both technicians and DIYers to sometimes be more efficient at repairing equipment. ifixit, a US based organisation, is one of many that promotes the repair industry.
As is the case with new equipment you should in most cases expect a warranty on any repairs carried out. Sometimes, because of technical reasons, a repair organisation cannot offer a warranty on repair.
E-waste is a global issue and an increasing volume of the waste stream. Repairing faulty equipment helps to address this issue to a dregree.
