Question about Philips SoHo 107T21 (White) 17" CRT Monitor
Hi, There is a very high pitched noise coming from the monitor; shriller while reproducing dark colours. The sound intensity reduces when the monitor is switched off and switched back on but slowly grows stronger again. Coming to think of it this sound has been always there albeit at lower intesity. Its only now, when the noise has become more shrill and painfull that I have been able to place the source as monitor.
It could be a harmonic noise caused by dust inside the monitor. If you are qualified (brave enough) to remove the back cover, blow the entire inside of the monitor out with compressed air (carefully) that may help. It could also be the flyback transformer. In that case, you would have to have the transformer replaced (I wouldn't recommend doing it yourself unless you are a TV technican as the CRT can contain a static charge of 14,000-25,000 volts- even when unplugged)
