Can someone give me some advice on this problem:
I bought a new 22"LCD monitor and put in my room. When my parents have the AM radio on in the other room, and my monitor is on, a high pitched noise can be heard on the radio.
When i turn the monitor off, the noise immeadeately ceases. The high pitched noise can be heard on all frequencies of AM band.
Is there any type of filter that i can buy or do to fix this problem?
