Re: Hannspree HF257 2-3 seconds black
Hi.. I have a hannspree HF257 monitor
if the brightness is maximum, it has the '2 seconds to black' symptom.
and when i set the brightness to the minumum (zero), it flicker several times with electrical noise like hum and eventually go to black monitor...
but the power led is on and the monitor works with very faint almost black image, and the sound works perfectly
Can you help me?
