let me know if you find out whats wrong with it..
i have one of these and they are fantastic monitors..
the power company where i live makes me feel like im living in a 3rd world country.
momentary power outages regularly and for no apparent reason, i remember 2 years ago for 6 months we would loose power for about 5 seconds every single day like clock work at 9am
we've had the same transformer 2 streets over blow up twice in as many years.. just suddenly POOF and you see a flash of orange or blue light in the sky and a big boom.
anyway enough rambling not sure whats wrong with mine.. we had a power outage one night, when we got power back the monitor never came back up.. amber standby light blinks faster then normal (normally it's a slow steady blink if it has no signal, now blinks twice as fast)..
i have no idea how to diagnose the nuts and bolts of a monitor nor do i wish to try, could'nt find anyshop that would touch it.
