I have KFC monitor with speakers built in, which doesn't seem to work.
I opened my monitor and tried to figure out wheither speakers are dead for real or there's some other problem.
!!!As I suspected - speakers work!!! (when elcticity from weak battery was applied directly to the wires entering speaker (both worked) I heard clicking inside of speakers) - but what is the problem then(!?), and HOW TO SLOVE IT?
I had an idea (just guessing! my wild imagination) that maybe some transistors are "LOCKED" inside of the chip on the circuit to which speakers are conected (if something like that is possible, and I think it is - because it is known that there are types of transistors that can store an information even when they are not under vlotage). I don't know; just proposing some ideas to start you thinking. ...Maybe some stronger current was passed thorough the circuit, and the protective mechanism activated... How to "UNLOCK" it - if that's the case. How to reset the circuit, or maybe the circuit itself is dead?.. (gihly unprobable because it never was under such a huge stress!)
