Unsuccessful repair attempts

Everybody undertstand if you try to get always the cheapest way.
But beware: Cheap can be expensive.

Often the defective device ends up with the buddy with the hardware store soldering iron or trying to create a hand. True to the motto: "I have upgraded the memory in my PC", I disassemble my defective power amplifier.

In the age of "www", this trend is becoming increasingly common. Devices are opened on their own and repair attempts are made.

However, it usually turns out quite quickly that the defective device can not be repaired as easily as initially suspected. Even if optically defective components are successfully replaced, this rarely leads to success. It is usually more defective, as can be seen at first glance. Following faults and any cause present on the device must be found and eliminated so that a device works properly again.

Basically nothings speak against to try to repair it first, but often users makes more damages as benefits when disassembling the device.

  • Bent clamps,
  • Nicks on the cooling surfaces,
  • damaged vias,
  • torn tracks,
  • cold soldering joints,
  • charred components,
  • poorly calculable consequential errors or else
  • improperly cut thread

are often the result.

Not infrequently land such "craft objects" then here on the table. A possibly previous cost estimate is then of course obsolete. So if you are interested in a repair, please bear in mind:

Devices on which unprofessional, unsuccessful repair attempts have already taken place will not be accepted.
