all monitors, from 2000 to 2010 year, are backlighted with
crude CCFL maps, that last for 2 years (shortest life full time)

buy monitor 2011 and newer, and this pain above goes byebye
at the introduction of wonderful, LED backlamps.

More likely to have bad caps with bulging top in the power supply, that is the first place to look for the monitor this old, see example of failed monitos due to bad caps: http://s807.photobucket.com/home/budm/allalbums
Post back what you se sowe help you more.

carrt33, If unit performs same way when connected to fully booted known good pc with WIN-desktop as displayed output, I would then suspect a problem with the units SMPS/CCFL inverter power supply failing to sustain running voltage to the "cold-cathode-fluorescent-lamps" that provide white light so you can see all the pretty colors on the lcd panel. Read my FIXYA profile for more info and possible options you might have. Remember this! Your CCFL back-lit lcd monitor is no different than any other brand in it basic design and operation! 12fixlouie

Does it do the same with other PC? If it does, then you need to open it up and start looking for bad caps with bulgign/leaking top first, post back what you see so we can guide you further: see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

its a risky for you to open the monitor and repair its power supply, coz its your monitor's power supply prob..
please contact with warranty providers.

good luck

there is NO microphone on the fp5315 monitor. I have two of these monitors myself .
