Sounds pretty dead to me. Electronics these days are not constructed with the idea of repairing in mind, but rather that the entire unit will just be replaced. So there's generally not anything for you to "fettle" with even if you wanted to.
When it comes to knowing how to identify a computer problem, i can most likely fix it. But one avenue i've yet to travel down, is fixing a LCD Monitor.
I have a KDS USA 17' monitor that will not turn on. Prior to this it would show weird lines running horizontally across my screen whenever i would take it off the screen-saver. Then it started getting worse till the point that when i would take it off the screen-saver or turn the monitor off for a while, then back on, my screen would be a epilepsy causing pixelized mess. Atleast till i would turn it off, then back on. Or until the image would slowly return to normal.
So after a couple weeks of this it eventually would not turn on anymore. Whenever i hook it up, the power light would flashes for a second. Does anyone know if there is a part i need to replace? Or something i need to fettle with? Or is it just plan out R.I.P?
