Hello, I have a NOKIA 445pro monitor. I havent used it for 6 months and its screen now is completely black as if no power supply at all.

The small LED glows green, which indicates the monitor should be fine. However, it flashes very quickly which may be a sign of problem. Anyone has any idea what could be wrong?

Thanks Razz

The flashing usually means an error code depending on how many flashes and pauses I dont know this particular one is it lcd?if not and is crt check that tube heaters are lit if so you may be able to advance the screen volts or A1s that is the adjustment on the line transformer to display the symptom which if your lucky may be frame collapse (prob frame o/p IC)or even line collapse if heaters arent lit probable line output transfomer failure

good luck Laughing
