Troubleshooting methods

To understand whether it is possible to repair the board yourself, you need to carefully examine it. We'll have to test the parameters of the elements, evaluate which circuits have violations. Only a specialist with experience in working with microcircuits can cope with this task.

Replacing a part

If the board is faulty, then it is simply changed.... To do this, you need to purchase a new part. You can buy the module in online stores. The price for a part starts from 5500 rubles and above. The more modern and intelligent the model, the more expensive the module.

You can purchase a used work board. Such parts may be available in service shops, from private repairmen. However, it is impossible to guarantee their continuous uninterrupted operation.

Checking work

The wizard checks the operation of the repaired elements of the control board using a multimeter. The probe is applied to the part and the values ​​shown by the tester are evaluated. If it supplies food or gives out 0, then a short circuit has occurred, if 1 - an open circuit.

Master call

You need to contact a professional if you could not solve the problem yourself... Repairing a control board is a difficult task that cannot be dealt with without special knowledge.

For help, you can contact service centers or private craftsmen. Contact information for a specific locality can be found on the Internet.

Many repairers run advertisements in newspapers. Another option is to use word of mouth if you have acquaintances who have already used the services of such specialists.

When contacting private craftsmen, there is a risk of meeting with a scammer... Therefore, before calling a repairman at home, you need to study the reviews on the Web. As a rule, negative comments about unscrupulous masters are found on various forums.

If a specialist promises a free visit and diagnostics, and then demands payment, you need to threaten him with contacting the police.
