Question about Philips Computers & Internet
Hello erl, hi.... the hissing noise is usually caused by high voltage arching, but this is suppose to be soft. if the hissing is unusually loud, the high voltage transformer clip cap may be loose, this may cause the horizontal line you see on the screen. take precaution when dealing with this.... here are steps that may help..
1. unplug the unit. allow around 5 minutes for all voltages inside the unit drops to a safe level.
2. open the back cover. place the monitor face down on a table with a dry clean rug or towel.
3. locate the picture tube. on the top side you will see a wire with a cap at the end.
4. use or wear a cloth glove and feel if the cap is loose. re clip the cap and make sure it is secured.
5. replace the back cover.
