How to repair a monitor?

Question

Monitors

One monitor turned up on my arm here almost for nothing, can you have any suggestions on how to fix it?
Once I personally disassembled the same monitor, re-plugged all the plugs, after which it worked safely, in normal mode for about 20 minutes, and then again the same garbage. (that is, the monitor is working, the matrix is ​​intact). There are strong suspicions that just one of the wires is moving away, but in this case, why am I taking it apart now, and no matter how I pull all the wires, it doesn’t even react to these movements? And how do you find out what kind of wire it is? I'll change it, thanks in advance! Monitor SyncMaster940nw

The monitor is lit - most likely, the power board is working.
Find a similar monitor 19 "or 17", take the control board from it and connect it to yours, yours to someone else's, find the culprit. Think further.
