How to check the parts of a plaque.

[George1000]

How can I check the electronic parts of a plaque? I can't disconnect each one of them, check it and reconnect it because they are too much. Thanks.

I mean something like that, sorry for not explaining but I don't know English very well.

Short answer is: You can't!
Long answer is: Without knowledge of the circuit, proper test equipment, a surface mount rework station, and a lot of luck...you can't!
